Product Parameter

Input voltage: 5V/1A or above

Output voltage: 5V/1A (MAX)

Charging cut-off voltage: 4.2V ± 1%;

Battery over discharge protection voltage: 3.2V;

Input/battery reverse protection, input overvoltage protection, output short circuit protection;

Suitable for charging and discharging 18650, polymer, and other lithium batteries with a nominal voltage of 3.7V. Single or multiple batteries can also be used in parallel.

Product Matters Needing Attention

1. Pay attention to wiring according to the diagram and do not make mistakes.

2. Do not reverse the polarity of the battery

3. The input voltage should not exceed 6V, otherwise it will automatically cut off and may damage the components.

At the beginning of charging, the current is high and the heat generation will be relatively large. As the battery level increases, the charging current will decrease and the heat generation will correspondingly decrease.

5. During the charging process, the charging board should keep a distance from the battery as much as possible. When charging and discharging at the same time, there should be no short circuit protection and the current should be given priority to the load before the remaining power is used to charge the battery. Proper heat dissipation should be done,
