I successfully got the FlexMax 80 to charge 32v lead acid and have a FX2532MT inverter charger so I want to stick with 32v.
I just started reading on building LiFePO₄ batteries but I kind of expect the same problem, those battery management systems probably all designed to work with 12 24 36 and 48v ...
The first thing I though of is if I am stuck somehow with multiples of 12 is to build a 36v and just leave 2 cells unused.
12 cells in a so called 36v LifePO₄ , minus 2 cells or a total of 10 looks perfect for a 32v system.
They are fully charged at 3.65 volts and fully discharged at 2.5 volts.
That looks perfect. My 32v lead acid rests around 34 volts and all charged up and floating at 36.
