  1. Hi Im thinking of mass purchase this YKZ7250JG. Is it possible to use a battery with max discharge 200a? since im only using max of 50A from this controller. of course im thinking of getting higher controller, but is it still possible to use on YKZ7250JG which have a peak of 50A, Im using with a 3000watt dualphase motor.

      1. The 50a controller only support a peak wattage of 1800w, using a 3000w motor will burn the phase cable of the controller, or the motor’s coil.

  2. i am having troubles wiring my motor to my controller, it will always jerk even when I followed the combinations that were listed on top, can anyone help me with it?
