the original bms is oke?use the original bms.....a lot of wurk to build this like the original battery pack bud you wil have a wurking led on the battery and you can keep the original charger(no leds and original charger when use a other bms).

ิbms original is ok but i have problem battery is short distance (7 km battery 24V 8amp)
I used the original bms it can work. But it works very short, total distance about 7 km and very fast charging only 30 minutes full.
I think it's unusual.i will to change new bms but new bms have 2 wire

total charging time only 30 minutes full.(It usually takes 2-3 hours.)

so the bms is good....old cells are the problem,you need to rebuild the pack with new cells(7s-4p 3.5Ah cells to make a new good pack of 14Ah)
