Id be looking to load test them cells sag under load so how much voltage deflect you get per amp applied etc amd also check its heat output by doing a IR measurment you should have an idea of the losses to expect.
Ive done a bit of digging on the bms front and found active balancing and resistive balancing.
Active balancing acts quicker its equalizing the voltages the battery degrades a fraction less so they say, there's far less heat created moving energy to one cell rather than a resistor and heatsink so i found by having a read about.
I'm happy my resistive bms will suit its purpose its in a basic brushed ride and the most i want from the display is basic shunt functions and been just 1 cell in the pack balancing wont be to heavy anyway.
I found a jikong 24s 2amp active balance bms 200amp so ill be having a play around with that ive got a chargery so i can run upto 88.8v nominal for some real serious shit.
