I used to do a lot of scooter modification, mostly on the Currie/Schwinn electric scooters. Was know for the dual motor kits that I sold via EVDeals.com and directly. Also the Powerpack Motor brushless combo. I'm pretty much out of the hobby now but have a lot of equipment that I'm finally shedding. Including these controllers.
I see them listed at over $100 at Robotcombat.com. I think I listed them at Ebay for $55 but I'm open to offers
They can be picked up at ebay but I'm happy to deal direct with members.
So: 4qd Uni 8 48v 80amp brushed motor controller $55 obo
