I didn't check the little caps when I had mine opened up. The big ones are 63V.



It's a nice 22A controller. Has 9 MOSFET's.

I had two problems with the LCD display. (1) It cannot show speed on a coasting geared motor It's missing a speedometer input. (2) Pedal assist (5 level) is too strong. Accelerates too fast in PAS 1. I have spent a little time adjusting this, but it's not satisfactory to me. As recently as last Fall, customers were still having this issue.

On Amazon, he now sells a more expensive kit with Higo waterproof connectors. Pictures show a different LCD display too, so the above problems may be gone. It's just getting the right firmware.

I bought two ebikeling kits last year. One was the LCD version where I scrapped the controller and went with a KT unit. The second one I bought with LED and find it worked fine. I'll probably buy a second LED display to get the first controller working again. The LCD allows different battery voltage to be programmed, but the LED display has its voltage readout fixed to particular voltage. However, it still sends the right PAS signals.
