Two. Circuit board instructions
1, the store adopts advanced voltage constant current technology, can effectively solve the LED flashlight on the voltage constant current requirements.
2, special tips :A. do not overvoltage use, the voltage does not exceed 4.2VB. The battery is facing the front, do not reverse, otherwise it will burn board C. Pay attention to control the change of electrical temperature to ensure heat dissipation D. Non-professionals do not open the circuit board
3, warranty description: Open or handle the circuit board is no longer covered by warranty.
Iii. Lithium battery instructions
1, lithium battery characteristics: lithium battery and mobile phone battery charging method is completely different; Lithium battery has no memory, can be charged at any time, do not overcharge.
