Charging instructions: charging cable connected to the power supply, access to the battery charging, the red charging indicator light is always on, fully charged red light off.

Functional description: The charging cable has a built-in intelligent charging management IC, which separately balances the charging of the two batteries in the 7.4V lithium battery, so that the batteries can reach charging equilibrium. Three-stage charging method (constant voltage/constant current/pulse) ensures that the battery can be fully charged. Ensure the safe use of the battery and prolong the service life of the battery.

Battery precautions:
1. Turn off the device when the battery is low to avoid deep discharge.
2. Always disconnect the battery from the device when not in use.
3. Do not use or charge the battery if it is gassed, swollen, leaking, overheated or any other abnormal phenomenon
4. Never disassemble, puncture, shock or damage the battery. Do not ignite the battery.
5. Do not overcharge the battery. Improper use, such as short-circuiting or overcharging, may result in explosion or fire.
