Improved shunt resistors on the PCB allow for more accurate real-time battery capacity reporting on the LCD. Thermal Management: If this is a or driver module , versions like "v2
Switch between "Zero Start" (throttle works from a standstill) and "Non-zero Start" (requires a kick-off). The V2
The V2.0 version of this hardware often comes as a matched kit including both the internal motor controller and the handlebar-mounted display instrument.
