Feature:

1. No matter Lead-acid batteries, lithium batteries, water batteries, dry batteries.

2. All kinds of electric vehicle (12V to 99V) can be automatically identified and displayed in real time.

3. Through the voltage number to determine the fault of electric vehicle, twice the result with half the effort.

4. By turning the real-time voltage value can accurately determine the amount of remaining power, convenient for customers to drive.

5. The real-time voltage value can accurately judge whether the lithium battery is damaged.

Specification:

Green is for throttle hall signal, red wire is for throttle +5V, black is negative wire; please connect according to controller function wire, your can not just match same color wire, if wrong connected that will damage your controller and throttle.

4 wires : yellow is for voltage display wire, connect with electric bike power positive.

5 wires: blue wire connect with controller power lock output wire, yellow wire connected with controller electric switch input wire power positive,

6 wires ; yellow connected with power positive, blue wire and white is is function wire(can work as reverse switch, horn switch, cruise switch, power lock and so on)

7 wires: yellow connected with power positive, blue is share wire, middle gear for 3 gears , white is high gear, brown is low gear.

Basic parameters: according to different battery materials, old and new, different batch, the number of voltage v will be different, please test a few times, you can get your electric vehicle battery parameters.

For 12v electric bike, maximum voltage is about 12.6v, mini is about 9v or higher,

For 24 electric bike, maximum voltage is about 29.4v, mini is about 21v or higher,

For 36v electric bike, maximum voltage is about 42v, mini is about 29v or higher,

For 48v electric bike, maximum voltage is about 54.6v, /58.8v, mini is about 40v or higher,
