I just built my first 12v 4s LiFePo4 prismatic pack, and it went smoothly, but
The 16 280ah LF280Ks cells that I got from Amy Wan were very well matched. I am off-grid, and entirely 12v at the moment, so it made the most sense to build a 12v pack with bms, and bulk up the charge with my solar CC, and then separate the cells and parallel/charge them to TB. I chose the lowest capacity cells, even though they were all in the high 280s, and assembled my first pack. Well, after some cloudy days, the battery topped up today at 3.6vpc, and the cells appear to be in balance. The bms did a little balancing early on, but not too much today. Does this mean they are properly top balanced? Or should I hook them up to the power supply and goose them somehow? I could care less about squeezing them for juice. Happy to stay inside the curves.
TIA and for all the forum members. I travel most of the year in a yurt, and live in private campgrounds on jobsites for months at a time, and I'm off-grid about 10 months a year. I've been growing my system for over 6 years. My system has unique requirements, and LiFePo4 will be a game changer when it comes to loading up my whole home for travel Will, and this forum are the reason I feel confident to attempt this. Cheers!
