Best controller for 20S 3kW motor?

Post by BillyJ » Jan 02 2019 5:52am

Hi all,

Would you recommend me controllers for a 3kW motor, running a 20s 90A pack?

Also what is the cheapest FOC controller that fits these requirements?

Thanks! :D

Don't cheap out on your controller.

Kelly KLS-7230S is a very solid controller, it will handle your 90a with no problems.

After 1,500+ miles, I only have 2 issues with the controller.

1. Accel ramp is not very exciting.... power comes on a bit slow for the first 10-15mph, then it rips your face off. I use 3T high speed motor which exaggerates this a bit more. Controller puts more emphasis on a slow and steady start ensuring traction over speed.

2. There is no dashboard or display that just plugs in. There is a BT dongle for programming but nothing like a SW900 or LCD3 display. I currently use a GPS based speedo and a 200a shunt with it's own little volt/amp meter display.

X2 what @yermommy said.

I bought a sabvoton 72150 w/tft and it was complete trash(lasted 50mi). I'm running a Mobipus controller now, its FOC, not sure it's the cheapest. SamD sells them if you're interested, Good luck.

Just messaged Sam. The Mobipus looks very very promising! Thanks :D
