moonshine. the bms wiring is actually very simple, but it needs careful thought cause adaptto have flipped the plugs around, making it rather confusing at first.
as you have discovered, the boards blow easily when things arnt correct. i have blown a board by dissconnecting the serial sub-pack connections without unplugging the bms plugs first(which were bridging the serial connection)
general rule to be safe is- when unplugging stuff,whatever you do to the pack , ALWAYS UNPLUG ALL BMS JST PLUGS FIRST, and NUMBER ALL PLUGS.
as the components on the boards cant take any more voltage than they are spect for.
its good having the spare ones so you can reconfigure and use them.
try setting to ovs 5, 150A batt,350A phase
for me, this is where the bike started to feel like a responsive moto.
you can also soften the start current with ls start/hs start feature, thatway full power will not kick in until the set speed, say eg. 30kph, is acheived.
if you havnt already done so, try running autodetect several times. it improves the smoothness and efficiency again each time, givving more power accelleration and cooler temps.
also, cant recommend the atached wuxing thumb throttle enough.
really comfortable to use, good qual, cheap.
works right out of the box with the max-e, and means you rerely need to touch the discs
