Also first thing i did was put a load tester on the bank when i got it. Held 1000 amps without being charged at all. Im impressed and for the naysayers these batteries are the real deal. I mess with alot of batteries and these are incredibly strong for the money. Im am very pleased with my purchase.
Hey long time subscriber here I just bought 24 of your new sodium batteries I'm planning on putting them in my Prius would love to see some testing done on the cells I've been doing some discharge tests they seem to get a bit warm and the temperature rating is 45c seems a bit low I wonder what happens when it gets above that temperature thanx again
All the different lithium-based chemistries are going to have their pros and cons. You'll have to do some research to better understand which type fits your needs.
Ehhh not smaller/lighter unless you are getting some 30C+ LTO’s like Lishen or Scib. Energy density is so poor on LTO but some of the cells out there are the real deal. YinLong are overrated IMO
Not really. Your alternator will be the upper voltage limit and you will monitor the voltage when the engine is off. There are bms's or battery Management Systems that can limit current from the battery to a load and disconnect it if the voltage gets too high or low. These bms's are limited in current to a few hundred amps and can get very expensive. For car audio use a BMS just doesn't make sense.
Lifepo4 can handle up to 14.4-15 volts. Your battery under your hood is a 12 volt battery and is probably charging around 13.8-14.3 if you have a stock alt and if you have a high output alt you're 12 volt battery under your hood is probably charging around 14.4-14.7 and you just run your lifepo4 lithium battery in parallel with your battery under the hood but if you have a lto battery that can charge up to 16 volts you'll need a battery isolator to keep your battery under the hood from dragging down your lto battery while your vehicle is off.
Max voltage for Lifepo4 is 3.65v per cell. So 4 cells in series is 14.6 volts. Don't ever go above that. 14.0v to 14.3v is great for these cells. Even if your alternator puts out 14.7v or 14.8v when cold, its really the resting battery voltage that counts. So when you turn the engine off the battery needs to be under 14.6v
@@JasonWW2000actually max voltage is technically 4.20v but there is NOTHING to be gained above 3.60v. Your cells will be fucked if you charge above 3.8V or so but technically it’s safe
@@ericklein5097The max voltage I quoted was from the cells datasheet. Because the exact mixture of chemicals in lifepo4 cells can vary slightly you always want to look at the data sheets to determine max voltage.
make 3 more of this circuit, and make it a 48v 4800Ah + 48v input invertor for 3kw . you could probably run a full load 2kwh house power line for 1 day without a hitch, if eco usage maybe almost 2 days i think hahaha...
I don't think Doug has all the test equipment to measure these. Steve does have the test gear and can probably test it properly, but I kind of doubt he would be willing to do that. At least not for free. No doubt we will see these batteries popping up on big sound systems soon. So the feedback will start coming in as they become more common.
Im not starve Meade but I have the big fat version of the battery and I also have 2 8,000 watt amps I’m installing on it in the next month . I’ll be uploading videos
This would not be the chemistry you want for a 16 volt system. 14.6 volts is typically the max (3.65v x 4) and if you do five in series the max would be 18.25v. Much too high for most vehicles and amplifiers. For a max of 16.8v you would want to go with either lithium ion (4x) or lithium titanate (6x) cells.
I know your a battery guy, but for large amp the ONLY way to go is to use supercapacitors. They are the only effective way to supply the current you need when that base note hits. Batteries simply cannot do that nearly as well.
I'm not sure where you heard that. Look at a lot of high power systems (10k to 80k watts). Almost none use super capacitors. Its all about a big battery.
I just ordered the baby slim, The lifepo batteries work for sure. I ran a 3,000 watt Stetsom and a 500 w Alpine mid and high amp together running my AGM to a cheap $50 20 amp hour lifepo4 with my stock 150A alternator and my voltage drop was extremely minimal. I didn't use an isolator I kept taking my battery off in the morning to test the voltage of each and the resting voltage of the lifepo stayed the same and the AGM also stayed the same every time I checked

Yoooooo ...dis dude chillin wit RDJ! So he built the electric power drive system fuh his vw van ! Yea im sold!

If that cable was longer you could put that display further right, looks like a good home for it
that cable is available in different lengths
Where can I get the D plates for the terminals because they are out of stock?
that Battery looks great. I wonder what you would need to run a 1/2hp 120v well pump. If power goes out it would be nice to have water for the toilet.

What battery do u recommend for car audio these or headway or which u think I'm a noob to this I also have a 370a alt
I’m not jehu, but the lev cells are brand new and have 8-9x the amps of the headway… depends on your space and wallet
I just ordered the slim cnt wait its a bargin @@jeffreyabercrombie
yes these are better than a similarly sized headway battery pack. I tested this ua-cam.com/video/Rc-S90seAkg/v-deo.html
Could you put the buss bars underneath the pcb board?
Yes you can
@jehugarcia i just biught a slim 8 cell setup from you and found out i need the fat pcb board. Cant seem to find it on the site. Can you help?
isn't LTO battery better for car audio? smaller/lighter in the same power output.
yes at the expense of less capacity and higher cost

Energy density is so poor on LTO but some of the cells out there are the real deal. YinLong are overrated IMO
Wouldn't that battery need low voltage and high voltage cutouts?
All batteries do, this is a typical LiFePO4 cell voltage so 2.5v-3.6v x4
Not really. Your alternator will be the upper voltage limit and you will monitor the voltage when the engine is off.
There are bms's or battery Management Systems that can limit current from the battery to a load and disconnect it if the voltage gets too high or low. These bms's are limited in current to a few hundred amps and can get very expensive. For car audio use a BMS just doesn't make sense.
How are these batteries going to handle alternator voltage? I.e. 14.4v,14.8v or close to 15v

@@jbucku324The only lead based battery you can run in parallel with Lifepo4 is an AGM since it's voltage is higher than a regular lead acid.

where can I get that bus bar?
in the links

Would this work with me charging at 14.8v?
That’s 3.70V per cell. No point in charging past 3.65V. Honestly no point in going past 3.60V
But if your alternator is pushing that….3.70V won’t kill then. But don’t go beyond that
I love the 12 volt ❤ that’s what audio should really be
Send these to someone capable of doing some real world testing?🤔 say like steve meade or soundman or something

Can u show how to wire it to be able to get 16 volts ,?
,12 .is weak ,!

AM I THE ONLY ONE WHO THINKS THIS GUY IS STONED????? 😂😂😂😂😂😂 TAKE THE 100-INCH SHADES OFF ESAY😂😂😂...
I would hope he is 🤘
No, I think it's probably just the way you see people.
