Controller
The motor I'm using is not reversible so to make the tractor go backwards the trany is put in reverse. Trany has 4 forward and 1 reverse gear.
Right from the start I wanted to use a controller on this one, my 1st EV has non only a contactor and the tractor is jumpy as it has no clutch.
The motor specs say 45amps continuous, 275 peak.
I picked a Kelly controller 36volt, 80amp continuous, 200amp max. This controller will deliver almost 2x the continuous rating of the motor and this is what I based my decision on and that fact that it was recommended to me by a fellow EV buff. Also I bought the foot throttle for it.
I also got a fork lift battery charger, 36volt.
Painting has begun and tractor started to be put back together.
