I'd say Randy Holmquist at Canadian Electric Vehicles is the man to contact about SepEx drives. He's got a fair bit of experience with the 96V 500A Zapi controller paired with the Kostov and (I believe) ADC SepEx motors in his MightE Truck, and 5-ton Isuzu conversions. 96V 500A sounds a bit underpowered by modern EV standards, but don't automatically write it off without talking to Randy first or driving a SepEx vehicle; the behaviour is a bit different from a series DC system, and it might just fit your needs anyway. The real question is if Randy (or anyone else) has figured out a way to parallel a pair of the 96V 500A Zapis... Cheers, Roger.
