54 kph - 500W Bafang with modded KU123
In this video you can see a road test of my Bafang 500W 36v 201rpm overvolted using a 20S Li-Mn battery (74v nominal, 84v fully charged).
The controller is the standard KU123 (32A peak) modded with 100v capacitors and 100v mosfets. The original controller had 63v capacitors inside and 75v mosfets.
