Refurbished Ebike 36V/48V SW900 LCD Display

This updated one works better than the older one I had

With this SW900 I am able to see the instantaneous voltage of the battery and I am able to set P14. This helped me determine the problem with my Power Bar indicator that I had. It seems so far that P14 (controller amperage) must be less than 20a, at least for a 36 volt setting, for the Power Bar to function. The controller said it was good at 22 amps, but the motor needs to be thought of. The motor is 500 watts so 500/36 ~ 14a isn't unreasonable. The Power Bar stays at 100% otherwise on mine.
