I am rebuilding an old SCT electric Rabbit. It has a shunt/sepex motor in it and a 108 volt battery. Currently, it has a controller on the field but not on the armature. It runs by idling the motor at full field; you let out the clutch to start and weaken the field to speed up. I want to install a controller on the armature, so I can raise the voltage to the motor's rated 144 and get better performance on hills. Will the open source controller work for that? I understand that, without the series field, there is not enough inductance for some controllers to work well. Would that be an issue here? Another question is regen. The car has it, and I want to keep it. Will it work to simply put a big diode across the controller to carry the regen current to the battery, or is it more complicated?

thanks,
