A pure golf cart controller might be a little odd since the motor is a 
fixed-field motor and not a series or shunt (magnets). Still I'll take a 
look at that MC-7 one; I do want something to provide power to the front 
and rear lifts; I do not like tapping this NiCD pack. Unlike lead-acid 
it's a pain to get NiCDs back into sync even by overcharging.
