Will, thanks so much for the effort you put in to these reviews. They definitely are having a Darwinian impact on these manufacturers. You have raised the game for everyone with your most honest candor in your reviews, especially when things haven't gone the way you expected.

I've been following you for a while and I just want to give you a big thank you for doing a very thorough review of all the new solar products that come out please keep the videos going

That's some impressive build quality. This is first time i'm like NICE. NICE NICE the deeper you went in. Build with love and eye for detail. Seems like they really wanted to do a great job building this.

I am impressed. I have looked at these in the past and was wondering if they were as good a quality as they looked. I think they are worth the premium. If you want something that just works, these are a great option. DIY is of course much cheaper, but these are every bit as good as a Battleborn. BTW, thanks Will, good review as usual!

I'm running six of these in the 48V@100Ah capacity on our boat. They're working great! Awesome to see that the internal build is awesome too!

I have had the 12v 400ah for 6 months now. Love it!!! Bluetooth shunt would be a nice upgrade. Great price also. Probably gonna go up now. Electric car parts has many options for batteries now, more than when I order mine. Hope shipping got faster. It took 4 months due to US customs.

Ive been using the 12v 400ah version. For one year now. It powers my Electrofishing unit for Doing Fish Surveys. It replaced the two 8D 250ah Lead batteries i was using. By far the best battery for this type of work. It also has been in the boat the whole time in all types of weather with no problems. I charge it with a 210w solar panel with a waterproof 20a charge controller.Happy to see you review them.

Work crews setting up, tearing down and traveling around all day long will find these attractive. They look like they can withstand quite a bit of abuse. I'd have no problem paying a little extra for this build quality when touring.

"...C'mon guys, really?...it's been a while..." --don't know why that made me laugh so hard, but I can imagine every successful youtuber feels the same.

I swear the more I watch your teardown vids the more I want to just start building some crazy nice and heavy duty batteries in the $500-600 range for a 100ah to bring to market. Overall most people would rather buy a ready made battery with warranty, as opposed to build. Already a business owner, so Im more than familiar with the challenges that have to be overcome in order to build a name. First however would be to send the prototypes to you and let you rip it apart so that any potential shortcomings could be corrected. 😁

Nice looking battery, but kinda pricey. Looking at the pro version it appears to be similar to how a Valence ubms system operates. No bms fets handling cutoffs. instead using the communication port to handle all on and offs of chargers, inverters, relays etc once parameters are met. I have a similar setup running valence u27xps where the bms only turns off and on my chargers, inverter and SSR for non inverter loads. Example: voltage gets to low then bms sends signal to turn off my victron inverter and victron ssr for the DC loads, then the solar charger can stay on to recover the battery without loads pulling the battery lower. Definitely not for most people watching but this, however this type of setup is really good in industrial applications, ev vehicles and maybe very large parallel systems.

Reorganize the letters in PROWSE you get “POWERS”... coincidence?.. I think not💪🏼🤣 Great job! I’m trying to learn (good luck.. I may be a hard student to teach🤷🏻‍♂️🤣)

060221/2003h PST. Thank you for the presentation. I am totally blown away; at the sight of this Power Supply container. This is MIL standard, definitely. I have , in my life time, not seen any thing like this come out of China. Very meticulously assembled and tested. What’d be the cost of the big unit? Thanks again. Stay safe and 73s…

The real break comes with the 24V x 200 and the 48V x 100ah vs Battle born as both require $4000/4 units to equal VDC and capacity. Each of these is app $2280. Still not bad...

No screws missing! Excellent!

Just a quick tip: I always take a quick set of photos with my phone before I disassemble things with more than just a couple of parts or connectors -- just in case I can't remember how it goes back together :-D

Great review as always! I never get tired of you replying to comments that you find annoying lol.

Hey Will... what do you know about electric wheelchairs? Do you know what kind of batteries they use? My double spinal surgeries I had on January 28th and it has apparently flopped and I'm now crippled. I was told my electric wheelchair should be here in around six to eight weeks from now. Barring my present physical situation... I'm really looking forward to getting my wheelchair. It's a top of the line... Cadillac of it's venue... She had me test drive three different makes so I could select the one I liked the best. She told me I picked their best. 😎☕💯🇺🇸🧐🥴🤪😉😜🏰🎯

I always take a cpl photos of anything that I'm about to take apart.

It's nice to have the option to buy something that isn't built to a price point first and foremost. Even if your application is stationary, that padding could save you big time should something impact the battery. This probably could be serviceable, if one has a tap-and-die set, a good drill, and steady hands. 😁🔥👍

purchased my Calb cells 6 yrs ago from Electric Car Parts -

impressive build quality, the BMS connections looks super heavy duty/over engineered Edit: only downside is the cells are welded instead of bolted

This guy is so adorable and handy. I need him in my life

Thank you so much for the link to renogy, I bought the mppt controller and saved $58 total as compared to amazon price. Bought your book too a few weeks ago, great job Will... I went with the newpowa 210watt panels... waiting anxiously to get my system set up..

Very enjoyable, they look so well made. Love to have as a back up for the Ham Radio station. W4GSM

Just got your book in yesterday and would highly recommend! Just a matter of time will be building my setup and may build a battery. Great channel and thank you.

Ibuiing a teardrop. I was going to completely wire it up. Now I’m thinking a solar generator would be easier

This young man really knows his stuff

not done with the vid yet, but im waiting for Blue Carbon battery review or tear down. 😁

Another great teardown, Will! Impressed as well. Saw these a few months back & was wondering the quality. Agree, that BMS looks monster overkill! Any chance you can identify the make/model?Or do you know of *possibly* ANY made in USA BMS's? Or at least, non-China. And thank you - I've learned so much from your channel, about to take on my own first ever battery build, starting with buying most of the tools, connectors, wire, etc that you recommend.

0:58 normal Will 1:00 safety orange Will without even skipping a beat 😎

Will I got a 100AH Dakota lithium battery. Works really nice . Would you do a review on Dakota Lithium batteries. I don't recalling you ever doing a review on Dakota Batteries.

3:27. Impressed, especially if you're impressed.

Will can you review discover battery lithium blue series, it looks promising and have the APP monitoring, very cool...

THANK YOU!!!!! I was hoping to get some information from a reliable source on these batteries!!!!! I joined the forum and have tons of questions so looking forward to your future videos and your replies.

great videos thanks so much. I have been lpoking for a good 48v battery for my systems, thanks keep up the good work

Your reviews are awesome

How do you use a Victron Smart Shunt to control a heating pad, exactly? I would like to control both a fan and a heating pad inside my battery box.

Wow, those battery packs were incredibly well built, I was amazed by the quality of the engineering that went into those, great strip down of the larger version, I preferred the mini version though. Will, I have a Renogy setup here in Wales U.K. where we don’t get much 🔆🔆🔆🔆🔆 but we get lots of wind 🌬 🌬🌬🌬🌬. Have you ever considered wind power generation, as I’ve not come across any on your archives. Thanks for taking your time making this video. Rog from Wales 🏴󠁧󠁢󠁷󠁬󠁳󠁿.

Hey, Will. Have you considered doing a teardown/test on the 300ah battery that Basen sells on Alibaba? It's super cheap and some of the RV guys are buying them for their rigs.

You doing terrific. Keep up the good work

Great video as always Will! :)

That's why I always take pictures..lol

But the SOK is suck'n on delivery!!

Hey Will have you thought about doing a video on a DIY 48v li ion pack using a Tesla model 3 battery module? If you break a big module in half you would have a 12s lower voltage but at about 20kw. Setting the charge and discharging voltage limit you may lose a bit but still have around 15kw and a really long cycle life. Some of these modules are going for around 800-1200 + a little shipping. With two good bms and wired correctly to the bricks I think you would have a epic battery. Heck throw a cabinet on a wall and mount it in there too for safety. Let me know if you think it's doable and worth a shot. Thanks and take it easy man! Casey

Wow...really nice. Actually makes me want to get busy building an overbuilt monster 😁 Agreed on cost compared to SOK

Man I just bought four of the battle born 100 amp hour heated batteries. These things are half the price. Oh well, that’s how it goes

thx for your good videos! I dont have that much money so I got a used 2014 Hawker Armasafe 100Ah AGM battery, still 90+Ah left. Some people sell expensive purelead batteries for nothing because they switched to LiFePo4 (PV storage) Enersys EP & XE; interstate MTZ, Powersafe SBS, Hawker Odyssey extreme,...

Can these be run in series? I would like to be able to run them in some scissor lifts that I have. Some of the lifts are 24V and some are 48V and I would like to be able to move the packs around between lifts as needed.

Sadly, SOK's are completely sold out and will not be available until August!

I like the way they were built almost like military quality.

Always fun to watch you tear things down. :-)

Thanks Will! Wondering if you have you done a tear down of the Rebel batteries yet? I like there new metal can 106AH.

man i need 2 of them for our build..LOL until I have seen the price.. ouch.. well keep looking I guess :-(

Hello and thank you for all your reviews, it help so much. I have a question, i'm building a boat in France at a shipyard and I'm looking for a large battery IP66 for my 600W solar panel and boat consumption. I have this ECPC 12V 400ah in mind but you just made a review on the new Epoch 12V 460ah. Between the 2 (building quality, technology, marine adapt) what would be your choice? thank you for your reply.

Please do a review on the Gravity 800 AMP CAR Battery Capacitor GR-800BC.

Hi David, are these better made than the Gyll cabinet that Poz was showing. I would live to see a tear down, I trust your opinion more.

Those look like some nicely built batteries. Im very impressed sir! Take care Will

So would you think the 12 volt could be a good replacement for a travel trailer battery vs 2 agm

thanks for posting !

Beautifully made--but shockingly expensive.

Would Love to See You take a look at the new Ecoflow Delta Pro!

Always take pictures when taking things apart!

Enjoy your videos more education than I could ever dream of, great job. Do you have in the agenda to turn down and do the revaluation of a Dakota 100 amp hour lithium, peace to keep the good work up

Thank you for the awesome videos! Can you possibly review the CHINS and JITA batteries on Amazon? Very low price, built in BMS.. but ya know the old saying! Thanks again!

Off topic but what you think about the Ford lightning electric truck? They let you power whole house from the truck that’s kinda cool... I doubt testla will follow suit as they have home power wall products already

Thanks for all your work. Well done! 😎 -- Mark

It looks great but read the sale guide it says all sales final on batteries

Looking to make a big battery purchase for off grid house and wondering if you have any thoughts or a review coming on Signature Solars EG4 LL batteries that will be back in stock soon? Pairing with ET bifacials and a 12kw growatt all in one.

Have you reviewed ‘Chins12V 300Ah’ lithium Iron Phosphate battery? Curious of your evaluation.

I would like to see an off grid system for a helium miner. Low cost possible but with decent quality parts.

Enjoyed the video since I have a Bestgo 400Ah (ECPC) and love it but didn't want to void the warranty by breaking it open. Your cost comparison confused me though. I paid $1930 for the ECPC/Bestgo 400Ah, shipped which also included a spare remote meter and cabling. I am seeing a little over $1000 for the SOK 206Ah and since you'd need two of them to make 400Ah, that makes the SOK more expensive. What am I missing? I tested the Bestgo at 10A draw rate down only to 2.8V/cell cutoff and it put out 430Ah, quite impressive.

Hi Will , Just wondering what you do with all these batteries after you check them out ?

Thanks again for the great video

It would be nice if you post links to sites that provide international sales. Many companies only ship inside USA or only in Europe

Not sure how to post this. 3 weeks ago ordered Bluetti AC 200P. Screen says AC200, tested unit with kill a watt showed 1.68 kWh at a 398 watt draw for 4hrs 30min. The case says 2000kwh and 2000w Not BMS screen to show number of cells. Doesn’t have forward button to show it. Also no indication in manual or on screen or label what the chemistry is or number of cells. Did I get ripped off? Have sent maxOak report through Amazon waiting to hear results on replacement unit. Screen Also shows variable watt draw ranging from 60w to over 1100 on a heat gun set at 395w over the 4 + he testing.

Hello, I have a quick question. I have a yeti 3000x, hooked up to six 100 watt panels of the 50amp input GZ Anderson cord. I'm currently taking my garage fridge and deep freezer off my grid with this setup. Is this process practical or will it hurt me long run? Right now it's sustaining itself and haven't seen it drop under 40% even on the cloudy day's and providing only 250 watts of inputs. On sunny days I've seen 579 watts. Any inputs will be appreciated

How about some micro inverters?!

Forgive my ignorance but let acid batteries require maintenance, thought the lithium-ion did not. You're talkin about replacing cells, replacing bms? ... not a set-forget? Was Mechanical Eng a LONG time ago.

Only thing don't like on these is the cheap little display, but of course their going to sell for more $, the SOK's are sold out on their site.

OK Going fishing on this one!!! I have 6 x 100ah bbb w/ Victron Multiplus 2000. The main draw is an DC AC Proair RT Unit & It draws between 60-100 amps. So it last between 5-8 hours during the a hot summer day. What would be the best way to add run time. Is it more batteries or is it a small 2000 watt gen. I just need maybe 1-2 hours more. Oh, I have an Panasonic 330 watt panel and a 2nd alternator with Balmar MC-614 voltage regulator that helps repowers my bank. It does a great job when drive on the highway. When I get home, shore power does the rest. So what should I add?

You are the best man 👍🏼👍🏼👍🏼 you teach me a lot about lithium battery and solar panel and solar system I built my RV solar system by your recommendation thank you very much 🥰

So I want to install a separate breaker box to run a backup solar system with. It seemed simple enough to me but now I’m confused about bonding neutral. Would I want a ground bonded neutral box or not?

Very nice video, great information on them.

Thank you for what you do!

Hey, does the website you link for the hybrid inverters ship to Alaska? Having a hard time getting anything up here because most websites claim to not ship up here because we are ‘outside’ the US.

For those prices they should have a Bluetooth BMS.

Anyone know whos BMS that is? Thing is a tank! I'd love to pick one up for my build.

I live in South Africa and is easier for us to buy from China, where do you suggest the best place to buy and what to buy. Thanks

2:01. SPEAK. "Overkill."

What 220 amp BMS are they using?

(AWESOME intro to the video, to.)

You should review chins batteries. I haven't seen anyone on RU-vid review them yet.

Have you ever try a capacity test on the Meritsun power wall battery bank. 10kw, ?

Great video, I would love your suggestions on powering a indoor Nebra Hotspot, which is all the craze right now. Nebra hotspots mines a crypto token called HNT. I have a 3 party outdoor enclosure. I’m thing of using a solar chargeable battery

lol the battery is Will proof and certified

Can you build a stand alone..... mini split ac unit running solar....?

Lol curiosity wins! "Let's open this one"

If these ECPC units start selling that tells BattleBorn and SOK they can raise their prices $100-$300 and their still less expensive. You charge what ever the market will bear.
