1-6-09 Razor E325 (not E300) upgrade with 600W+ mobility motor at 36V, 11T front and 65T rear sprockets. Has good pickup on the homemade 8kHz PWM speed control and 3 SLA batteries. Top speed is about 25-30 mph which it reaches too quickly. The Batteries were almost dead in this video. After we recharged them, the scooter was MUCH faster but quickly burned out our speed control (we didn't have any protection circuitry and there were huge long power wires in our design which caused a horrible inductance problem and 1000V+ voltage spikes destroyed the mosfet. Since then we have fixed and upgraded the SC but there is too much snow on the ground to test yet.
