Product Size: 28 * 17 * 4mm
Product weight: 2g
Input voltage range: 5V
overvoltage protection: 2.5V
charger current: 1A
Charge cut-off voltage: 4.2V ±1%; Battery overcurrent protection current: 3A; The input terminal has a MICRO USB socket, which can be used as an input power source to charge the lithium battery directly;
Instructions: 1. The MICRO USB socket and the +- pad next to it are the power input terminals, B+ is connected to the positive pole of the lithium battery, and B- is connected to the negative pole of the lithium battery.OUT+ and OUT- are connected to the load and can be connected to the positive and negative poles of the booster board or other loads. 2.

It can be used for charge and discharge protection of 18650, polymer and other lithium batteries with voltage of 3.6V 3.7V, and single or multiple batteries can be used in parallel.
Special Note: 1. When the battery is connected for the first time, there may be no voltage output between OUT+ and OUT-. At this time, the protection circuit can be activated by charging the module with DC 5V voltage. The battery is disconnected from B+ B-.The above also needs to be charged to activate the protection circuit.When using the mobile phone charger for input power, note that the charger and charging cable must be able to support 1A current output, otherwise the module may not be able to properly charge the battery; 2. When charging the battery, disconnect the load on the OUT terminal. The positive and negative poles cannot be connected incorrectly.
