So I currently have a Bafang 48v/500w rear hub motor and the controller for it is 20a max. I am considering upgrading to a KT controller (25A) to get a little more power out of the motor. It seems no one really makes a controller over about 20-22 amps that is a direct swap for the type of controller that typically comes with bafang hub drives, at least those for the motors rated at 500w or less (the higher wattage bafang motors have a 3 pin connection for the motor instead of the 9 pin that I have). So I have a few questions about exactly what to order (and yes, I have been doing a good bit of research).
1. I am planning on ordering a controller like this https://www.aliexpress.com/item/32960618313.html?spm=2114.12057483.detail.3.5fa33c25N1pAK5 and am wanting the 25a WP model as it looks like it has the HIGO connectors. Will I be able to use my current 1-5 cable to run the display and throttle. (the connectors look the same) or do I need to order the 1-5 cable specifically for that controller?
2. I currently have an 850c display that came with the motor, and from what I have been reading, it looks like I will have to order a different display for the KT controller. Can someone confirm this?
3. Should my current pedal assist (magnet wheel) work with the new controller if the connectors look the same?
4. It looks like there are KT controllers that have a higher amperage, but the controller motor connection is a 3 pin (which comes on the larger bafang hub motors) rather than the 9 pin (which comes on mine). Would something like this https://electrobikeworld.com/products/3pin-male-to-9pin-female-motor-adapter allow me to connect my motor with the 9 pin connection to a controller expecting a three pin connection (I know that the the three pin connection actually carries up to 8 inputs/connection signals)?
Thanks in advance!!
