Its currently in our shop
We just replaced 2 batteries (after 3 years). The thing is CRAZY fast... I've never gone full throttle. It'l do a burnout. We broke 2 front wheels doing doughnuts around the shop. Its pretty neat.... 2 AC controllers, hooked to 2 alternators (we just broke the windings out so there were 3 phases, and ran them out to the controller). The alternators have slip rings and a field coil in the armature (it doesn't commutate). The AC controller has 3 phases and an extra output to "excite" the field on the armature. Fully programmable, regen, 150A per phase, 60V.
If there's enough interest, we'll start making them again.
