Instructions for use:
1. The battery box is suitable for 2.5-4.2V 18650 lithium ion rechargeable batteries (please use batteries with the same capacity and the same model)
2. Connect the output port of the 12.6V charger to the round DC port of the battery box for charging
3. The DC circular port of the battery box is 12.6V, which can be output or input. The 5V USB port is only used for output and can be connected to digital products, such as mobile phones and LEDs
4. The USB output can reach 2000mA, which greatly shortens the charging time.
5. Waterproof rating: IP67
6. The magic belt makes installation easier and more convenient
7. This product has over-charge, over-current, over-discharge protection, battery reverse connection protection., balanced charging. Five protection functions
8. Charge batteries of the same brand with different capacities together, first charge the low-capacity battery, fully power off, and then charge the high-capacity battery. Assuming that the 2000 mAh battery and the 3000 mAh battery are charged together, the 2000 mAh battery is charged first, and the power is completely cut off, and then the 3000 mAh battery is charged
