Can You Use Solar Batteries for Car Audio? Reviewing The Power Queen 100ah Lifep04 

Nice vid bro...always like those battery videos

Great video , thanks for sharing

Great testing bro ❤😎

Excellent comparo!

Well explained 👏

It would be interesting to see a test of the fluted and the solar together against the Headway, simulating alternator, stock battery, plus the solar as a second battery, vs alternator and Headway bank.

Been a while since I seen you man and good to see a new video

Good stuff! For DIY with high current capability _and_ BMS protection, you can use a solenoid disconnect as your 'safety'. The BMS can trip the solenoid on over or undervoltage, but no limits on current by the BMS. (Of course, you need to specify the cells so they're good for the currents you want. Headways, some of the bigger 60AH/280/320AH cells are good for 100's of amps discharge without breaking a sweat.) I just got a big bank of 280AH CATL cells to run the house during power outages. (Often, here in the redwoods...:) And I think Jag has some 12V 60AH packs for $150ish, no BMS, and they're good for a few 100 amps discharge. The other trick with those mini 12V 100AH batteries is that they can run in parallel for more current total. They're smallish and light so that can work pretty sweet. Just be careful to run quality equal length cables from each battery to your common plus and minus points so the batteries/BMSes will share the load accurately. (Follow HiFiVega's cable videos!) Active balancers are great for DIY setups, especially with used/repurposed cells. My three current li-ion banks running the house are using recycled scooter batteries. one bank has a regular BMS and an active balancer. It was the earliest built, most heavily stressed bank and it's staying super nicely balanced. Bank 2's active balancer failed (not it's fault) and I didn't replace it. It's currently off-line due to too much variation. Bank 3 is newer, (featured in my channel's 'explod-y" video, actually), and larger. After swapping the damaged pack, it's running ok, but without an active balancer. Yet. I have to manually balance it every few months. (Or maybe I should install another active balancer. Soon.) The 20KWH CATL LiPo pack will have active and standard BMS/balancer. Still working on it. 4 of those cells (about $550) would make a 50lb, 280AH pack about the size of that big car batt in the video that would be able to push 840A continuous without a peep. That's the cell rating. Definitely need a solenoid type BMS. (Or just use a small BMS to monitor voltages and such and alarm if it's getting close. That'd be cheaper and no losses thru the mosfets. (OK, I shut up now. As HiFiVega knows, I'm an ancient electronic tech who's been messing with batteries (From tiny to room-sized) for over 50 years. It's an addiction. And a budget HiFi nut. Just can't do the physical stuff for car audio anymore. It bites...:) Stu Have a great one!

It all depends on the discharge rate, the higher that is the better they are for delivering extra juice when needed and normally these lithium batteries have a much lower rate than the ones specifically for car audio

Sweet thanks that was my question, great info man... I'm only running a 3k system i think my agm battery will work for me, just for sum extra juice..

A Power Queen with a 200amp BMS would be a great test.

Thanks for the test. Would have liked to see an AGM thrown in there for comparison. I'd really like to see you run a test on a 60AH, or greater, Antigravity battery...

Great video thank you

this can also be a good house battery in your car truck or van , some people spend a lot of time in their vehicle and they do want to run the fans or the radio but do not want to have the engine on. so this battery with a relay and some few loads directed to this battery should be a good setup . there are many works vans where they require mains voltage and use an inverter , this can be smaller and more cost effective bulk storage for the such vans. lifepo4 can put some serious load on alternator and will fry any factory alternator so the regulator needs to be modified with a thermal switch at minimum that will turn the alternator off if the temperature goes too high.

What lithium battery can be used under the hood of a vehicle the will work along with headway cell?

I use a Power Queen 50ah battery in my Can Am X3 as a secondary battery for all my accesories including a Rocksford Fosgate Stage 6 sound system. The battery does great with no problems and i blast my music for hours in Glamis.

My homie!

Thank mate needed this video. What is your power supply you're using please?

Incredible video. Thank you for taking the time to do all the work and editing needed. My question is about charging off the standard power coming from an alternator. If you have a high output alternator (250amp) then charging the lifepo4 will be a challenge. How can you hook up this battery in your vehicle for stereo of you have it on your regular electrical charging system?

With my 220ah time usb lithium battery w 150a bms if it's not enough do you think I can replace the BMS and then it will be comprable to a headway? One more question I have a 50 farad ion capacitor by Rockville do you think that has the ability to make up for the discharge rate being only 150? I have two AGM's run parallel on the other side of the isolator

Nice job

Can use anything you want as long as your entire system is speced and matched at least electrically

Not a great idea to get a solar battery on car audio but if you have one around or can get them real cheap then you could. The BMS robs some power (PCB, MOSFET R(ds), monitoring circuitry) and the worst part is, depending on the BMS, just a hint of under or over voltage and you get locked out! I would be curious if you can get hold of real cheap LiFePo4 32650s/32700s like we could (~$2 a piece) and build a bank with it and a balancer, would it be better than flooded? Then we have LTO...

What if someone buys it and replaces the bms and change it out with balance board

I would love for you to test the benefits of pairing an Ioxis ultracap with headway

Hey bro I have a 5000RMS 12 inch blackdeath sub woofer and smart 3k teramp waiting to get wired up what battery would you reccommend someone said 225ah commercial been quoted £250 bit low on cash dude??

I have 4 of these same batteries connected in parallel for a battery cart and I successfully used them to jump start my neighbor's car that wouldn't even try to start with my Audew lithium jump box.

So can I keep my flooded battery and add one of those p04 solar in the back of car?

Hey I am new to anything other than your basic lead/acid battery with a cap in the back I've been gone for over 10 years and I'm trying to get back into car audio and I'm watching all these videos saying lithium is the new way to go for car audio first I should say my car is not compatible with a HO alternator (2019 Toyota Camry LE) so all I can do is upgrade my battery system and wiring for best possible performance from this particular car and I am having a really hard time understanding what I need to make it work I know I need some type of BMS that doesn't restrict discharge and I literally just learned that part from this video so thank you for that but I don't understand what type of BMS I need for say an LTO bank ying long style to charge without destroying my alternator as well as burst discharge can you please tell me what kind I need for a car audio setup I've been trying to research it

So here’s my question. I have 198 amp hours of limitless lithium in my car audio setup. could solar panels be used to keep my charged when my truck is off????? if it can be done, just wondering what exactly what I need. My resting voltage is 13.2v all the time. Running voltage 14.5 +- . Thanks for any help.

What about UPS batteries?

nice one for this test ....and i was wondering there is a community that uses car audio set up using server psu modding it sort of 12.4 to 13.2 something like that this setup usually done at home hmmm just wondering if that also can do heavy setups but i guess gonna need a ton of power for that. any ways thanks for the effort.

Good video

Great video! Does that mean the solar batteries may work but it will take more of them? With an appropriate ah ratio to current demand🤔

I am considering the power queen option for a boat sound system … I don’t necessarily need a ton of amperage all at once but a lot of capacity for playing without a motor running also the sound system won’t be nearly as large as the car audio systems these days … maybe 2-3k watts total at most and not playing at full volume… from what I can tell this may be a good option for me feel free to correct me if I’m wrong

Power Queen does say it needs to be stood up and not layed on it's side.

Great job explaining. Guys don't understand the cells have a C rating that limits discharge amperage necessitating a BMS to make sure you don't damage them.

Ok but can u mix the lithium with a … AGM or a lead acid battery to run a sound system

Does Power Queen say that 13.5v is 100% SOC? Typically it would be 14.6v. So I'm a bit confused.

Will a 250amp alternator be to much for the power queen batteries?

I'M looking for a battery that can hold the charge when i bump my suB with car off!!!!!!! no lookin max out put power

I would’ve liked to of seen the solar battery as a secondary on the ever start AGM.

Could I remove the BMS and just install a balancer since almost all car audio lithium battery banks don't use a balancer anyways?

Id suspect the solar lithium on a 10k system thats sucking 700 to 800 amp draw that it will alow its maximum aloud amperage output

What kind of amp hour lithium would I need to power a Taramps 3000?

How come the amperage wasn’t measuring?

Can you believe I have all three in my setup in the work truck. My AGM battery weighs like 75 lb I think

Is there a way to do away with the bms and use it?

What about charging? New alternator regulator? DC-DC converter? What does all that cost?

Id like to have the best battery for the cheapest price for daily use. But will run aroun3k to 4k watts

Will my stock alternator charge this battery thanks for the video

Hifi the battery whisperer

Price point wand watts out put isn’t that bad you really won’t know the difference with a sub

In the defense of The Power Queen, it's only rated for 100amps continuous discharge. You should've went with one of their larger batteries that are rated for how much that amp can pull.

Come on give me good news I'm just turning it on just bought a 200 ah timeusb give me good news please

This is a very good test, however.. To make the test totally fair, you would have to eliminate one variable - the voltage. These 3 batteries had slightly different starting voltage, so I believe that influenced the clipping point. I think you should have discharged the lithiums to be at exactly the same voltage as the flooded, and then comare them. Even if lithium is 50% charged it is still charged and for these short test the SOC won't impact the results. More of this please👍

LiFePo4 aren't great in colder climates. They don't like freezing temp of 20f or colder without a way of warming them before charging.

funny i was just looking at an electrovolt lithium on ebay wondering the same thing.

"Solar Batteries" are great for one reason. They have a BMS. Meaning? Even when you drain your car dead? The Battery is still going to be fine due to the BMS protecting the cells. Meaning? Long life for you and a good value for those that don't use Battery Tenders etc. So its more of a set and forget type deal. Unlike with Flooded and AGM's that we often have to replace every year or less in daily driven rigs. They also don't deteriorate anywhere near as fast as AGM or Flooded cells in daily use. * I have made my own Lithium pack and its been going strong for about 4 years. That's SOMETHING! And these are USED CELLS! Since we are geeking out here? The best of all worlds would be a 16v Battery internally with a BMS & 16 volt to 14.4 regulator built in to handle voltage drop. Kind of like the old Jacob's electronics box that used to keep up your voltage in your race car. The best of both worlds moreover still us to use SuperCaps for Burst in the same manner has they have Zero issues with charge and discharge, but that would only be for something like competition systems. The power would be expensive to keep clean at that point and the regulator would be horrifically expensive. We are talking about something akin to what you would use in a Prius for drive electronics. Overall? Seem to me that using the high voltage on a Hybrid from the battery pack onboard seems to be the way to go. It already has a Battery, the biggest "Alternator" out there. And it just makes sense.

Love you please don't change DIg me and everyone are dropping him sorry

Im kinda disappointed in the 64ah headway bank...been fed 100A from that power supply..I really did expect the least amount of volt drop...but wasnt the case...even if Headways are able to do a 5c continuous discharge...that 64ah bank should easily do 300A with such noticable volt drop especially while having 100A charge on it...at 1700w....its not even a 200A load.. Im disappointed.. If it stayed in the mid 13s on all Your testing...then I would have said well done

👍👍👍...

They are not rated for high amp draw or charge

How dare you call this a nerdy video while not wearing a lab coat 😂

I played this on 2x speed and it was still boringly slow. Cant imagine normal

lol " Solar Batteries" they are not solar batteries, they are Lifepo4 cells and or batteries. That may have a main use for Solar energy storage, but that's not their main purpose. Also the BMS on a lifepo4 battery doe snot artificially limit power, it has a cutoff, If it goes beyond the rating of the BMS it will just shutdown, not "limit" how much power comes out, they are not that sophisticated. I've been working with Lifepo4 cells for over 6 years now, and its scary to watch people that don't completely understand how to use these cells try to explain to others that don't know. I recomend that everyone read the spec sheets and read up on how a BMS Works (Battery Management System) that's connected to the cells for charging and discharging.

with 100 amp power supply and 100 amp limit on bms thats 2000 watts, try it with higher wattage and it will fail

🙈 *Promo sm*

Hay hifi you mentioned the BMS i just got the original Beast module its going to be 64ah like yours my question is do I leave the BMS hooked up at all times or unplug it after it balances
