The new version speedometer is build for Votol controller, as the communication protocol should match with each other.
In LIN communication, the controller could match with the speedometer, it display battery voltage.
In CAN BUS communication, the controller could also match with the speedometer (SiAECOSYS CAN protocol), it display battery SOC if the battery protocol match with speedometer.
If not, the speedometer will show lack of electricity always.
Thus,we suggest to do the speedometer as LIN communication version if client can't get can-bus battery.
