Today some more testing, had to lower battery amps to 200A otherwise bms would cut due to low voltage
Cells were supposed to be able to 270A continuous
Hi How's it going - as the Nanjing Far Driver, North American Region, District Manager and Business Development Lead I am so proud you chose our product. For this bms limitation issue specifically I may have a suggestion. If the cells are indeed rated for 270A continuous discharge I reccomend bypassing the BMS output and routing the DC output directly from the battery to the DC terminals of the controller.
There is a low voltage setting in the controller and the safety net of the MOE overcurrent fault which ceases controller processing instantly if an overcurrent moment arises. It's there to protect both battery and motor.
One other suggestion I can offer is that you ensure that the bus cables are equal to or greater mm² diameter then the phase cables. It's difficult to ascertain whether your build meets or exceeds this requirement. Keep in mind that the controller can, but rarely will double your bus current. Although when it does it is only pulsing that current for a third of the time that the bus cable is so its carrying its load one third of the time the bus cable carries its load which is constant. Even when it is double or even triple it would be less or equal to what the bus carries constantly over time.
Hopefully that is understood and not too confusing.
Great build and hopefully you'll be enjoying your mean green machine on the road soon!
Sincerely
