Description:

The lithium battery charge/discharge management module is a miniaturized power solution designed specifically for space-constrained devices. Featuring a high-density integrated design, this module delivers efficient charge/discharge performance of up to 2.4A and supports multiple safety mechanisms, including overcharge and over-discharge protection. Simply solder the battery to quickly build a prototype system, significantly shortening the R&D and validation cycle for smart hardware products.

Important Notes:

1. The output includes short-circuit protection, but the battery interface lacks reverse connection protection; connecting the battery in reverse will cause damage.

2. Due to the compact design, some heat dissipation capabilities have been sacrificed; noticeable heat generation occurs when the operating current exceeds 2A.

3. Does not support charging Apple devices via a Type-C adapter; Apple users should exercise caution when purchasing.

4. Charging current depends on battery capacity, discharge rate, current battery voltage, cable length and gauge, ambient temperature, and other factors.

5. Automatic switching between buck and boost modes has a 1–2 second delay. After the battery is fully discharged, the module will maintain input power to charge the battery. It will only automatically switch input/output modes after the charging state ends. When powering devices with reverse power supply capabilities, please disable this feature or exit charging mode promptly.
