Paired with 4KW-4.5KW Kelly Programmable Motor Controller(KEB72601) Peak Phase 280A Continuous Phase 110A (which I'm told at 'normal' values its 55-60a continuous, and 90amp peak)

Ordered 72v 20ah portable lifepo4 (65a continuous, and 85amp peak discharge). Going to make a secondary 18650 which I'll explain further down

Wheel 7000w peak, but 72v x 90a is 6480w.

For kelly programming QS told me to put motor current at 100%, and battery current limit to about 70%.

so 70% of 120 is 84a. 72v at 84a = 6048watts. QS say that it can do 7000w peak

to get this exact number it would mean 97.22amps at 72v. This would mean setting the battery current limit to 81.01%. I dont want to damage the wheel or controller, but I still want max performance. I suppose I should just go with what QS is recommending?

Some initial wiring - will be connecting the (+) out of ammeter to PWR so it gets turned off with ignition
