Hello,
I've been looking everywhere and couldn't find the right BMS for multi lipo cells sins all have a too low discharge voltage too high of a charge voltage and mostly slow balance current(Bad for my big 3S 22AH battery which I want to charge with 30A)
Now I'm less worried about the balance side of things and I'm looking for a good method to use for reading the voltage of each cell(that would not cost too much sins I've seen IC's that can reach 10$ alone)
So I started doing something with arduino, a few voltage divider resistors for each cell and some calibration at the end and found out how unstable and inaccurate it is...
Also would like to know of a good over current protection solution(Already got the charge / discharge circuits made).
Does anybody have a good solution for that?
Thanks for your time!
