About charging: On the charger, the red light indicates the charging status, and the blue light indicates full. The original charger can be charged with USB and a power bank. With the original charging conversion cable, you can use the model aircraft's balance charger to charge it (you need your charger to have the function of charging a single-cell battery, such as A6, PL8, etc.). When the navigation light is not used for a long time and the battery voltage is too low, use the original charger to charge it. If the charging cable is accidentally connected in reverse, the red light on the charger will also light up. Reverse connection for a short time will not damage the aircraft lights, but it will cause the electronic components in the aircraft lights to heat up (the battery will not be damaged or heated up). Reverse connection for a long time will damage the aircraft light components. Special Note: Pay attention to the positive and negative poles when charging, otherwise the equipment will be damaged. If you find any product problems after receiving the goods, such as damage and incorrect quantity of goods, please contact the seller immediately.
