    Is just impossible to find a BMS for LiFePO4 so I decided to design one for my Off Grid house. It is specific for my needs so max 8 cells in series and can use solar PV panels up to 40A to charge the battery. I have 8 cells 100Ah GBS not that great in therm of discharge rate but more than enough...

    I would like to know what is the real deal behind the BMS, What does it exactly do? I've done a research on this forum, and a lot of people talks about it, but every body is saying something different... What are the real risk on the lithium batteries so we should use BMS? And is there a real...

    I'm starting an experiment to test the effects of using lithium LiFePO4 cells in parallel with cheapo lead acid batteries. Lithiums are 40 AH Calbs, and they'll be boosting 29HMs (formerly known as 29DC) and GC8s. My current frankenpack consists of 3 29HMs and 11 GC8s. Phase 1 of FLHE will...
