2 3s 16650 in parallel
#9
Inductive loads need more current to start than to run. If you have a clamp meter that works with DC and can give you an inrush current reading, test the circuit without the BMS and find out the maximum amps the motor draws at initial startup. Make sure the reading is less than the number of Amps your BMS is rated for. If your BMS is refusing to let your motor start up, that means the BMS is either in short-circuit or over-current protection mode, and is preventing the motor from completing its circuit with the battery. Use a higher current rated BMS, or use the BMS you have as a signal to a relay or solenoid that can handle the motor's load.
