The sweet spot for this motor, pump & fluid was around 8.3 volts, .5 amps and about 190psi.

I tested with 12v direct to the motor. I might try 6 cell battery. I might ask are u running a second lower voltage battery or are using the esc to lower the voltage? my down pump in the excavator that is tether to a 12v dc source. I have no need to run an esc on the pump.
