Instructions for use

1. The voltage and current of the charger do not match your battery. The charger parameters you purchased are incorrect. Please tell us the parameters and plug of your product brand model or original charger.

2. Due to the limited life of lithium batteries, if the battery is damaged, the charger will not work. If not used for more than 12 months or 2-3 months, the battery may be damaged.

3. If the green light is on when you plug in the power supply, but after connecting the bike, the green light will not turn red, but the green light is always on, and the charger does not work. This could be a loose connector. You can use another connector in the box to screw on the original connector and plug it into a power source for charging. If it still can not be used, in the case of confirming the voltage and current consistency, it is the problem of the charger, which can be guaranteed.

4. If the green light is on when the power is plugged in, and the rear light is off, it is an internal short circuit, resulting in self-protection of the charger. You'd better check your battery and replace it.

In order to extend the battery life by 10 times, avoid using less than 35% of the battery, and do not charge more than 85-90%
