Forgive me if this is not the right place/forum. I primarily build audio electronics but I have a question about charging LiFEPO4 batteries. If it makes any difference, I’m using it to power small speakers and other audio related mobile gear.
I’ve been searching the net for a while and can’t seem to find an answer about how to charge a 12V Lithium Iron Phosphate battery. It came in a small UPS but the BMS failed so I disassembled the whole thing down to the 18650 cells and purchased a new BMS on Amazon. I now have it fully assembled and would like to make an automatic rechargeable battery bank. The chargers I find online are either USB interface for a single cell or hobby chargers aimed at people that want to charge a bunch of individual cells or charge them in a balanced configuration.
I found some articles and videos where people use a CV CC DC-DC power supply. My question is what else I need and how I would set it up. I see other modules that are supposed to act as charge controllers but they all seem to be aimed at people interfacing with solar cells. Is the BMS supposed to cut off the charging or is that the job of another component?
Basically, I just want to set up a system that I can plug in to the wall when power is available and not have to babysit the charging process.
Again, sorry for the seemingly random question. I imagine with all the smart people on this forum, someone has some experience with batteries.
Thanks,
