Tips:
Some customers report that the meter head does not respond after wiring. After investigation, the customer is unfamiliar with the electric vehicle circuit. It is assumed that it is only necessary to directly connect the charging interface or the electric handlebar. This is wrong. In order to safely charge the interface, the MOS tube or diode is often used to isolate the battery from the battery. The electric bike driver controls the motor through the controller, so it is not the battery 2 terminal. In fact, the electric vehicle's circuit is relatively complicated. For those who have no basic knowledge of electronic circuits, please be sure to directly connect the 2 terminals of the battery or find a professional to connect, otherwise the display will not work or be damaged, and the traffic safety will be caused in serious cases. Remember!
