Short answer: the battery will probably outlive your off-grid project. Just don’t cook it, torture it, or freeze it.
Honestly, lots of people just connect them directly — usually works fine. But the proper way is to match the voltages first. Doesn’t hurt to do it.
I wouldn’t do it. Without a controller you have zero control over voltage or current, which is too risky for LiFePO4. A small MPPT isn’t expensive and keeps the battery safe.
13.8 V works, but it won’t fully charge a LiFePO4 battery. A charger that can reach 14.2–14.6 V is definitely better. If you want full capacity, you’ll need an LFP-compatible char...
Yeah, I’ve done it once, but honestly, I’m not sure I’d do it again. It’s pretty tricky, especially with the BMS and all the connections. If you’re not confident, thin...
