11. Weight : 16g(no Terminal);19g(with Terminal)

This is a step-down charging module with MTTP function. Please note when using it:

1. If the output fails after connecting to the power supply, please check whether the MTTP voltage is too high, and reduce the MTTP voltage

2. After the CR charging indicator is off, it is still charging, which is a normal phenomenon

3. The output current (charging current) is determined by the capacity and power of the battery. The maximum current cannot be directly output without connecting the battery.

4. This is a buck module, the input voltage must be more than 3V greater than the output voltage.

Applications:

MPPT So
