1A 12V MPPT Solar Panel Controller Li Ion LiFePO4 Lithium Battery Charger Module

1A 12V MPPT Solar Panel Controller Li-Ion LiFePO4 Lithium Battery Charger Module

🔹 Detailed Description:
The 1A MPPT Solar Panel Controller Module is an advanced Maximum Power Point Tracking (MPPT) battery charger designed for efficient solar energy harvesting. It supports single or multi-cell lithium batteries, including Li-Ion, LiFePO4, and Lithium Titanate batteries. With an adjustable output voltage (1.2V–21V) and an input range of DC 7V–28V, this module is perfect for solar battery charging applications.

The module can deliver a maximum charging current of 1A, which can be adjusted by changing the Rcs resistor. It also features automatic charging control, overvoltage protection, and an LED charge status indicator. If no battery is connected, the module functions as a stable voltage source, making it versatile for different power applications.
