Ok, so I found this. https://www.aliexpress.us/item/3256804906372669.html Really cheap LiFePO4 batteries. 70 bucks for 400Ah. Thing is, I don't want to burn to death. So, just how bad can someone make a battery? Is there a limit to how bad a battery can be? Are they lying? How do I get a good...

I've got 2 14.5v LiFePo4 batteries, and I'm fairly poor still. Thinking of charging it with the car battery using one of these. Or more accurately 4 of them in parallel. Is this reasonable?

Shit, I already bought the Daly.

What do you guys think of these cheapo BMS? Get or pass? https://www.amazon.com/dp/B09Z6N4CBN https://www.amazon.com/dp/B07T8NWKV7 ... context I got some Ironworks batteries, and the BMS and one of them is fried. I'm gonna replace the BMS and thought it would be a considerable additional cost...

Nvm, I found some Daly. I had not yet wielded my Google-fu. Why does everybody here seem to like Daly so much? I'm doing it because imitation, but why? https://www.amazon.com/dp/B08S2LZC9V/ 30A https://www.amazon.com/dp/B08RXWV6PY/ 40A JBD Equivalent...

Do you think you could share the pics with the forum? Replacing the BMS on that battery with the Daly is really useful information. I myself have one dead Ironworks battery, and I want to rejuvinate it.

I'm probably going to use it continually a little bit all the time, constantly charging it, and occasionally using a lot of energy. My plan is to charge two of them in parallel at 10A x2 with two DCDC chargers on the car's two cigar ports.

I'm gonna put my up to date research here. This thread: These sellers are mostly scammers they sell air, not death traps. Also it seems store age is one indicator of legitimacy. However I still have not found a Chinese manufacturer.

Please tell us what you get when you recieve.

Could I just set the voltage to 13.6 and never fully charge the batteries? Would this be better/worse for the batteries?
