1S 2.8/3.6A Lithium Battery Charging Module Battery Charger Protection Board Power Supply Charging Indicator USB Charging Module

1. Made of high-quality materials, durable and practical. 2. Exquisite appearance and beautiful arrangement of components. 3. Up to 93% output efficiency, automatic recognition of input current, adapter adaptation. 4. Low power consumption without anti backflow current diode. 5. The module has multiple protections to prevent overcharging, with output short circuit protection, and the board is equipped with built-in over temperature protection. Product parameters: Working environment temperature: -40 ℃ -85 ℃ Charging indicator light: red light for charging, blue light for full charge The two points of NTC can be connected to a switch, and after a short circuit, the module stops charging the battery Battery wiring (multiple batteries can be connected in parallel, cannot be connected in series, and the wires cannot be too thin or too long) B+: Connected to the positive pole of the battery B -: Connected to the negative electrode of the battery

Attention: The current mentioned by the module is the battery terminal current, not the input current of the 5V terminal. The current of the 5V terminal is smaller than the current of the battery terminal The higher the charging current of the module, the greater the heat generation, and the battery cannot be connected in reverse
