  1. Universal voltage, fit for 12-84V electric bike or scooters, can identify voltage automatically, timely indicating. (12V, 24V, 36V, 48V, 60V, 72V electric vehicles can be used directly, part of the 84V electric vehicles can also be used.)
  2. By turning the real-time voltage value can accurately determine the amount of the remaining amount of electricity.
  3. To avoid traveling on the way without electricity and accurate judgment
    of the lithium battery is damaged.
  4. By turning the real-time voltage value can accurately determine the judge the quality of lithium battery.
  5. Automatic to identification electric vehicles' voltage under 100V, universal used and real-time display.
  6. Universal throttle for electric bike, scooter , tricycle, and other electric vehicle.

Common sense for battery voltage

Different battery materials, new/old condition of battery, and different controller data make battery voltage reflects differently. Please check your battery voltage data according to your battery.

The maximum voltage indicates full charge. The low voltage indicates that the battery is exhausted.

12V ebike max voltage 12V, min voltage 9V
24V ebike max voltage 29V, min voltage 21V
36V ebike max voltage 42V, min voltage 29V
48V ebike max voltage 54V, min voltage 39V
60V ebike max voltage 72V, min voltage 49V
72V ebike max voltage 84V, min voltage 70V


Installation method:
With the car key switch, yellow wire connected to the battery +, blue line controller car key switch wire +.
The car key switch can not be used directly as the main power switch. Otherwise it will burn the wiring harness! Remember! The key switch is to turn on and off the power supply of the vehicle by controlling the internal electronic switch circuit of the controller.
