TIPS TO SAVE $1000s - DUAL BATTERY CHARGING - What you REALLY need to know about 12v setups! 

Apologies team - had to re-upload because a few technical hiccups in it - our sound guys obviously knocked off and went to the pub early! Enjoy!

Finally a decent 12v explanation video. I constantly have customers why their batteries have clagged out so quickly when they’ve run them to 0% or they buy a 50amp charger and expect me to install it on a 120ah agm battery with a 30amp max charge rate or they want to run a 3000w inverter off the same 120ah with a low recommended discharge rate. I think I’ll find myself sharing this video to them. It’ll save me hours in calls, messages and emails. 👌🏼👌🏼👌🏼 thanks shauno you legend.

We have just bought a 2017 Ford Ranger Wildtrak and starting to slowly set it up. Just bought a 140ah Giant battery for duel setup. Wanting to run lights, fridge and charge camera gear. Not long been in the 4x4 world and find your vids extremely helpful, keep up the great work team.

My son and I are doing up a GU Series 2 wagon as a joint project car - currently running a SBI12 isolator and one of my hand me down batteries but for our Cape trip later this year we're upgrading her to a LiFePO4 and BCDC1250D to run his fridge and camp set up. Love your work Shauno, education disguised as entertainment is a winner!!

Keen to see the camera cars set up!

Hey Shauno, I have a 2019 Triton with a stock standard Hitachi battery. I'm looking to upgrade to a dual battery system like you have in the dirty 30. I would love to have a break from work and travel around Australia to explore our country and give the kids an experience they will remember for a lifetime!

We have a 11' GU patrol with a isolator dual battery system. In the back we run a 60lt fridge and also have a van attached. I've purchased 2 slim agm batteries to go in the back of our patrol instead of a huge one under bonnet and a better charging system would be a dream! Loved watching this episode, great& informative

Busy building a VW Amarok (for me. Brother is doing a 105) to tour to Namibia. Starting to build my canopy soon. We have to be completely self sustainable, so this is a must for both of us. Shout out from South Africa!

judging from the content of this channel, I thought it would have some multi million subs. Keep up the great work and the boys will get you to a mill

Awesome video gents! I was literally hunting around for a video on 12v setups earlier today, so must've been in the air already. I've got a Ford Ranger with a Tommy Camper on the back (you Oz boys build bloody tanks when it comes to campers). I have a solar panel and the next thing to tackle will be the DC to DC and lighting/charging outlets (just building the courage and letting a few more paychecks roll through). Will also be running a small Engel fridge, lights and a heater for the chilly NZ nights. I've learned heaps watching your videos, so congrats on succeeding where all my school teachers failed. 🤟🤪

Hey Shauno, love your content - thank you mate. I have a 2011 Nissan Pathfinder which I’m typically towing the camper trailer for the family. Currently I’m running dual 100AMP AGM batteries which I try to top up with a 120 watt solar panel to keep the fridge cold and lights on. Keep up the great work.

I recently picked up a 1998 Landcruiser 105 and absolutely loving it! It came with a simple dual battery setup and cheap isolator. I'd love to set it up with a reliable 12v system ready for touring this beautiful country.

I've got a TD42 GU Patrol with a 200AH lithium battery

I’ve got an old gq bus, redarc isolator, kickass 170ah, with a kickass solar controller, and all I want is cold beers 24/7

2001 GU patrol. About to do the whole redarc system (dual battery, solar on my RTT, fridge and phone charger in the back on the wagon). Had no idea until I watched your redarc video and this one 👌

Good day Shauno, I have a 2003 Perado 120 and keen to put in a dual battery setup with a Lion SMFDCM31 12v CCA 800 battery. These videos make it so much easier and make me excited! You have saved me from ruining my batteries with my charger. Cheers

Yeah good second time watching it

Damn, thought that notification meant I’d won 😜

Hey Lads, Love the value you guys are always adding, a huge thanks🙌🏻 I’m setting up my 2016 Colorado for touring and work (sparkie) so we can travel from Geelong to Nhulunbuy to see friends. Big thanks.

I have a 98 jeep cherokee xj, I have a yellow top under the hood, a yellow top in the trunk. I want my system to be able to keep my fridge cool, charge flash lights, and to run power to anything needed at the campsite or if worse case to be able to use long term in a bug out situation. I'm gonna wanna run solar at some point too.... Thanks for all the info shauno this subject seems soo easy but is actually kind of technical and you and gram, jocko and the whole crew inform us sooo darn well... thanks 24/7..... you make overlanding soooo appealing ...

2010 Prado with single century 100a/h deep cycle battery running off solar alone through an MPPT and solar blanket. Really just looking for the ability to go away with the missus and enjoy the Aussie bush for a little bit longer and to go a little bit further than the average bloke. Power my fridge, LEDs, charge my kit, water pump etc. Cheers legends

Hmmmm feel like I’ve seen this video a few hours ago 🤷‍♂️

Hey guys as an accessory fitter myself this is a great insight video for everyone else to learn and understand there setup, shoutout to Shauno! Got a 2006 D40, wanting to do a redarc bcdc with a slimline battery setup behind the back seat would looove the redarc redvision setup too with a few outlets around the car for those camping trips away with the family or just a beach trip!

I’ve got a 1988 hj75, currently got an old redarc isolator and running 2 old deep cell batteries. Working on updating the whole electrical system and jumped on your channel to get some ideas. I work as an arborist and end up out the bush heaps so I run an inverter, fridge and need enough juice to keep my climbing saw battery’s running. Pretty clear now I’m saving for the redivision.

Land rover discovery 1 I'm just building my 12v system up after finally chasing down all the rot 😂🙈

Really want something that will charge all my milwaukee batteries and run the fridge

2021 MR Triton, this video is perfect timing as I’m looking at purchasing a Fridge/Freezer & camp lights & it’s helped me decide on which path/battery I need to go with to get the best results out of the 12v set up.

Hey Shauno. I’ve just got home from three days in my backyard. VHC. Started at Dargo up to the beautiful Bluerag. Camped just near Mt Freeout was amazing but my old 12 v isolator system failed me. Fridge out not good at all. Just watched your recent 12 volt advise story. Please please my 2009 hilux canopy setup really would appreciate a new REDVISION upgrade. Appreciate all you and the guys do keeping us updated. Keep it up mate.

Hay what happened boys I’ve gotten the notification twice

Need to run a second fridge so the misses ‘food’ doesn’t take up all my beer room

2014 ranger, 170amp deep cycle battery, running a fridge, Inverter,lights, cig & USB Sockets, travel buddy. Good video to explain to people that don't know. Great stuff 👍👍

2004 gu patrol 2 x mf95d31l 810cca batteries Long range touring and off road is the goal set up. Being able to go completely remote but be self sufficient! Love the set up in dirty 30, that system is impressive! Great tech there from redarc delivering the goods as always!

2012 d40 Navara with a tray an canopy which I tow a camper with, I’m aiming to be able to charge 2 batteries in it to run a fridge an charge camper at the same time so we can camp off grid for longer periods of time. Cheers fellas great videos as usual!

Hello Shaun, Thank you for this latest 12 VDC information and tips! I needed this now as I have a project, modding a full size pickup and pop top camper. My truck has a Cummins 5.9L , so, two batteries in the engine bay. My camper will have 2 deep cycling flooded batteries, also adding Solar panels, to keep everything changed I hope when on a walk- about! I need a a Redarc dc/dc on board charging setup! Keep up the great vids and off-road adventures! Instead of cheers, beers to you and your crew Shauno!

After watching 20 videos. This is the first one that mentioned fixed voltage alternator. Thank you, that was the information someone actually needs. I'm guessing the other channels I watched just want to sell a product, because fixed voltage is pretty important information that they all just happened to leave out. Cheer man !

Hey Shauno, I have an 80 series with dual agm deep cycle batteries running the first RedArc charger you showed, which now I've learnt is the wrong charger for my car. When I'm back in Perth definitely going to swap it out. Great video, thank you!

Building up my U.S.1994 jeep cherokee. Wanting dual batteries to run lights, 12v accessories and a refrigerator.. Thank you Shanno for these tips and tricks.

I have a 1996 FZJ80 with stock battery setup. I just got lights and I’m saving up for a fridge so this video is perfect timing because I was looking up how to setup dual batteries. I think I’m gonna go the charger route like you were suggesting. It would be an amazing prize to win. Also thanks for the amazing content y’all put out. Y’all basically got me into off roading!

I have a 2018 hilux and looking to install a dual battery setup to run a fridge,rear tray lights and external lighting on the car with also having the capability to put a solar panel on for when I’m camped up for a couple days! That’d be the ideal setup for me! Keep up the good work guys! Much love from WA

Great info video! I have a 2011 Toyota Tundra. I go over landing pulling an off road camper all most every weekend. Weather never stops me. Rain or snow is part of the experience. I run a freg, air compressor, marine oven. I have no Solar yet. My truck has a smart Alternator with two batteries. DC to DC 2 30 amp factory spec batteries. I will be upgrading at some point to solar but will stay with a DC to DC system. My new project is a 1978 fj40 LC. It has a LS 3 crate motor, automatic transmission, power steering, and air-conditioning. Should be on the road in about three weeks. Oh yeah the tub is all aluminum. Thanks for you videos I follow your channel all the time. Great work!

Hey Shauno. 2020 Triton. First 4wd. Great video and so informative. No battery hence watching this. My dad used to take me camping when i was a kid and i would like to do the same for my kids so slowly getting into everything 4wd/offroading/camping/fishing. Thanks and love the videos!

Landed in the country 4 weeks ago from the UK, bought a 2011 GU CRD today (my first ever 4WD) and my Girlfriend and I are planning to explore this beautiful country and do some beginners touring so just need to run a few lights and a small fridge for now. Starting out from our new home near Brisbane and its all thanks to you guys at 4WD 24-7 for getting us up to speed with the Do's and Don't of 4WD'ing

Just finished installing my basic dc-dc charger in my D40 but would love to make it the ultimate power house with the red vision system, it looks absolutely mint and to pair it with a 120ah lithium ion battery that's super light and durable would just be the dream!! Love your vids boys, keep up the great content! 🤙🏼

I have a tough as old boots 1994 LN106 that I bought to get into camping with my 3 and 6yo boys. I just scored a canopy shell that I have to fit out so a 12v system is exactly what I need right now.

Great info thanks. This was more informative than the so called experts at the camping shows. This is why my system doesn't work as well as it should. Now im up for new gear. I have a 2017 Dmax charging two 100ah deep cycle batteries in my camper.

Just recently got myself a hilux to start travelling in planning to run a 100ah lithium just to run a simple fridge and some lights and USB charging maybe throwing in a solar panel as well, great videos guys been binging 12v videos to try and get my head around it ahah

Hi Shauno. Thanks for the comprehensive overview. I used to have an old style dual battery system in my 80 series that always kept the lights on and 40l Engel cold. I’ve got a 120 Prado V6 petrol now. Just looking at 1 or 2 night camping trips with a battery under the bonnet as space is a consideration inside the cargo area. I run a 40l Engel and some led lighting. Looking forward to seeing more vids especially the HJ47

Perfect timing with this video and the info on chargers! Just purchased a 130ah lithium for my N80 Hilux and currenlty looking at what DC charger to get to complete the system to run my fridge, air compressor, travel buddy oven and a mid size inverter.

Gday Shauno!! Well done on the funds raised for the young fula to get to the U.S.A!! The clean up the bush movement is awesome work aswell. Ive been building up a '96 80series, 33's 2inch lift and turbo, intercooler and 3 inch exhaust for a while now. the missus and I got a fridge recently and man did it make a difference. The Redarc isolator we used with our 100ah second battery worked a treat. We took 46 beers in a 60 litre fridge and loved it!!! Now we need to build a great 12v with solar so we can stay out on the tracks even longer. Any help would be such a blessing. Keep up the great content we love you guys and the things you do to keep us moving in the right direction out bush.

Land Rover Freelander 2, Smart Alternator Charger. With a 1 and 3 year old on the trailer. Ensuring a solid power supply for heaters, bottle warming and generally keeping them safe is my top priority. Great vid as usual guys 👌

These are really great suggestions! and this is such an important topic to be discussing at the moment, I really enjoyed the video!

I’ve got a 1993 Toyota 4Runner. I’m running a 125amp AGM for my fridge, lights and for charging phones etc. Another great video guys 👍🏻

Hey Shauno, I Have a 1986 Bj74 13bt Landcruiser 120ah deep cycle agm battery and to run camp light for hours after dark, 45l fridge and charge phones to keep up with the inspiring videos.

New 09' hilux owner! Looking to setup a second battery system to keep the beers chilly. Thanks for doing this boys!

Hey Shauno and 4WD24/7 crew, I’ve got a 2018 76 LandCruiser and would love a quality Redarc system. Currently have a 105 AGM in battery box only. Need to keep the family well fed with my 60lt fridge, run camp lights and take a solar charger. Keep up the great work!

Hey Shauno, love ya work mate! Got a 76 that I'm trying to get setup for trips away with the fam, fridge and some lighting would make all the difference. 🤞🏼

Literally learn more from watching yous than anything else, keep em coming :)

TOYOTA FJ Cruiser, 2X105A, 220W solar panel. Running lights, 90l fridge/freezer. planning water storage and pump. Great Channel. Cheers from SA

Epic vid Shauno! Full newbie here and this is going to help me sleep better! I’ve got a 2000 Prado 3.4L V6 Petrol with a Century C12-120XDA 120Ah AGM. At the moment it’s only giving power to my lights, phone, camera battery chargers and a couple of other small accessories but soon I’ll be adding a fridge into the mix as well. At the moment that’s all I need for solo fishing trips up & down the coast. Cheers mate!

I've just bought a 140ah GIANT, Isolator installed, Ctek 25amp 240v Charger, but don't have a DC to DC charger yet. I've been running an ArkPak for the Waeco CFX50 fridge but want to step up the entire system in the 2013 RG Colorado. Love the show !!

2013 Y62 (Not Supercharged like Anthony's, I like to keep my CVs in 1 peice) 2 x 120a Bosch AGM batteries. Cheers lads, always enjoy your work.

Hey Shauno, I'm from California and I have a 1996 toyota 4runner that I'm building for extended trips into the wild. The final component I am missing is a 100-150ah lithium battery and a management system to control camp lights, power an inverter, and run a fridge. I have seen sooo many hours of your videos! They are the best 4 wheelin videos on youtube! keep em coming please! hopefully another big trip is planned for the near future? Cheers!

G'day Shauno, I have a 80 series landcruiser and have just the two agm batteries at the moment. I am hoping to get a set up that let's me and the boys get longer weekends away and not having to worry about the beer getting warn, or the push starts to get home. Keep up the great work and stay safe.

Have a 2017 nissan navara. It lives in the forest with me literally. I need a smart charger to charge a sealed battery to power a webasto hot water tap and a fridge, oh and my batteries for my power tools if required. Love the channel keep it up guys. 💪💪

Awesome video Shauno … keep them coming. 2020 Mitsu Pajero Sport owner here, got 120ah AGM (not installed yet) wanting to run fridge, lights & air compressor for hitting the beach dunes.

Hey shauno, I've got a 105 series landcruiser that we have been setting up the past 12 months of covid for a trip of a lifetime with the fam. We are gonna need power for all our camping lights, chargers, small appliances and most importantly our fridge to keep all the iron jack just the right temperature. See you on the tracks

Just scrolled through all 1400 comments looking for another Ford Everest owner and only saw one! Info is hard to find on outfitting the Everests so been watching a heap of your videos, thanks! Reckon I've missed the boat here but worth a shot: Ford Everest, looking to run a 200ah LiFePO4 battery with solar input for keeping our fridge, area lights and a few other creature comforts going during weekend trips and when my partner is on field work! Keep up the great videos

We're building an Ford F150 and just getting started. This helps ALLOT! Thank you

Hey guys I have a 2018 ranger wildtrack that I have been very slowly modifying I do not yet have a duel battery set-up but is one of the next things on the list to get my fridge powered without the car running and to power accessories Love the show keep up the good work.

G'day shauno, love the work you guys are doing at 4WD 24-7, keep it. Im driving a 2017 luxy with a simple AGM battery box currently. looking to upgrade as I travel remotley for work for weeks at a time and need a more powerfull and reliable system. Cant also forget about the weekend trips with the lads sinking beers and taking the piss out of each other.

Building a trailer for the jeep wk 3.0. Two lithium battery's in tow! With solar. Just got back from a show that redarc taught a class on 12v systems. Looks like at a minimum I'm going to need a manager 30. Thanks for the video it will make it easier for me to explain to friends.

This is great, thanks Shauno. I have a 1998 Toyota 4runner, and I currently have just 1 Optima blue-top battery and I'm looking to use these tips to install a second gel-cel deep-cell battery to run my winch, heater and battery chargers.

Great video! In my 2017 Hilux 2.8, I have a DIY 128Ah lithium battery with a Victron 30A DCDC and a Victron 75/10 MPPT coupled with a 100W solar panel. All this to keep the fridge full of cold beers, the freezer full of steaks and a couple of LED lights.

This video was great and perfect timing I just bought a pajero sport and I have a home made camping trailer with my fridge, lights, 130 ah battery etc. And am trying to decide to put a second battery or moving the trailer battery to the car. The more I research the more confused I get. I am new to this 4x4 but don't want to compromise the cars electronics. That's for the video great information.

I'm a battery nerd, so currently running twin 280ah 12V LiPo (Lithium Polymer) home builds with custom BMS setups on each. They take stacks of charge and can run an entire camp including great tunes for a long weekend without a sweat.. Love it! It's currently not tied to the 12v on the Disco due to LiPo charge profiles not matching alternator output. Instead, I use a home charging system to top things off for now, with future plans looking towards a Redarc or similar with 2 solar briefcases for longer trips, and a 2nd alternator custom tuned to put out a constant 14.6-14.8v charge profile to match the heavier needs of my LiPo setup.

Lot of good info and simply explained. I have a 2010 Prado 150 and a 135ah AGM to run my fridge, lights and charge appliances. I would love a complete dual battery setup.

Recently purchased a second hand patrol gu wagon that I’m slowly piecing together for a tourer. You sold me on the redarch red vision sound like its the ultimate 12v system for my build!

ive got, 2 105 amp batteries from century, gonna be running one 80 litre fridge to start with and will upgrade with time, built my own drawers and im just looking for the right charger, if its australian owned its brilliant, these videos really help cheers

Just. Managed to find 1989 80 series 1Hdt. Would love to put in a huge aux system for fridges, freezer, lights, water pumps etc! Gotta keep the boss happy!

2020 ranger and just starting to set it up for camping with the fam.. so thanks for the vid it’s really help me..

As a member of two fishing clubs (a ANSA saltwater club, as well as a freshwater club member) I'm just about to set up my 4x4 with a dual battery system i.e. I've bought the Dometic fridge and a solar panel, so now I'm saving my pennies (while still having a fish and enjoying a cold one, haha) to buy the DCDC charger etc. Cheers for uploading a informative video and in my case well timed.

I'm late for the competition but I was thinking about a solar charged dual battery system to run ditch lights, winch, light bar and fridge on my 4runner. These type of videos are super helpful, I'm learning a lot and planning on a good set up.

2005 Mitsubishi Pajero. About to do my first 12v system. Keen to run a nice and cheap touring setup!! Fridge, lights, compressor, etc. Thanks boys!

Got a Prado 2015 model. Me and my two littles love going on beach trips with the fridge. I run 2 batteries 140 Ah agm and 100 ah agm. Keeps the beet and chocolate milk chilled. Cheers Sal

Hey Team! We've just brought a 2003 Holden Rodeo (3L T). We've had to replace our crank battery as the old one went flat in 2 days of owning it! We brought a century. We are preparing to do our first lap around Aus - so are looking to get a deep cycle, dcdc and inverter. We've got the solar panels ready to hook up!

Hi Shauno been saving hard for the best part of 2 years now to buy my first real 4x4, I have decided on the Mitsubishi Triton (after watching your 20/21 best ute shows) as it offers best value for money and reliability, I am about 6 months away from purchase and have been slowly buying bits and pieces to have it ready for the tracks asap, I am going to run 2 x 140 Amp/hr AGM as lithium are still way to expensive. I have 2 old 40L fridges and a 1500w sine wave inverter, I just purchased an induction cooker as well under $60 bucks works well (would love to cook up a storm like you guys do) I will also be carrying a 120w solar panel for those lazy days.Myself and the wife want to trip Australia so a touring set up would be amazing. Keep up the good work love your content.

Just bought myself a 2011 lux to build from scratch and hit the cape in August for my 30th! Will be running a 120ah lithium battery and looking at the Redarc Manager30! 🤙🏼🍻

Hey Shauno, 1984 HJ47 ute. Currently running dual batteries with a Redarc Isolator under the bonnet. Making this into a touring rig and fitting a full canopy on the back and will be hopefully running a third battery in the canopy to power the accessories.

I’m 1 month in to my lap around aus and have a pretty basic red arc isolator with a 100ah battery in my 105 Landcruiser but If I’m parked up for a week or so even with my 200w solar blanket I’m not getting enough charge to power my 75L fridge and accessories so I’m currently looking for a better set up, this video has helped a lot, cheers 👍

Always something to learn. I've got a 2003 WG Jeep Grand Cherokee and hooking that to our almost finished homemade camper which will cater for the 5 of us. Still need to do the electrics on that though. I'm going to install a 100Ah AGM battery as that's all the budget will allow. I'll be running it off solar and to the car.

Hi Shauno! Currently in an 08 prado! Just running a 102 amp battery with an isolator setup, didn’t really know much about 12v so I thought that it would be a good way to get started just for weekends away but now doin my research I wanna upgrade to the 25amp dc dc charger and a bigger battery so I can start doing bigger and remote trips cheers enjoy the froffs 😋

2003 Jeep GC WJ. Oddyssey battery considering lithium battery for my second. Currently building and undecided on charging setup. Thank you for the informative video.

1986 GMC K20 Suburban. 2x 100ah AGM 12v cells. She's ancient but reliable. I was lucky enough to find one with a 4-speed manual. I love that tank. Don't run anything fancier than a fridge or maybe a hot plate if I don't feel like cooking with propane/butane.

Ford Ranger PX3 Dual cab, standard battery. Planning on a dual battery system to run; Dometic fridge/freezer, camping lights, air compressor, maybe a water tank. To be adaptable to solar so I can stay longer off grid and enjoy the great outdoors. 😁👍

i got a daihatsu feroza, got a deep cycle battery in currently, just need to run fridge and basil lights while out bush, thanks for the charger boys!

98 xj Cherokee, planning on setting up a dual Battery 12v system to run fridge and other basics like lights for Camping with the kids 👌

Prado 120 dual battery which I use for camping and overlanding. Dcdc system would be awesome. Appreciate your work guys keep it up!!

Nissan Navara 2008, no battery in it just yet. Saving the pennies for a AGM and an isolator. Great video thanks for the info!

G’day I have 2011 hilux, with one 105amp dry cell dual battery in the back. And I use it for my fridge and lights in the canopy as well as some portable lights when set up at camp. Thanks Todd

Did comment on the original upload, but here we go again haha. I'm in the process of making my 12v system. I've got a 1995 Suzuki Vitara LWB My second battery is a 100ah Lifepo4 lithium. I want to be able to charge the lithium battery without stressing out my alternator, and I want to be able to run a fridge, camping lights, air compressor and phone chargers. Getting the car ready for a camping trip to tassy in May Thanks for all the videos :)
