3.DKD LCD speedometer, can-bus(optional, LIN as default)

 

It display D N R, P, S gear, and battery current X5/10.

P.s.: If the working battery doesn't have can-bus communication, then the can-bus speedometer will shows lack of electricity always.

So, we suggest to do the speedometer as Line communication version if client can't get can-bus battery.

With Reverse, Parking button( throttle on/off), 3 slide switch gear, s/boost button, Light and Horn.

 It match with VOTOL controller well.
