AJMRTC XL4015 DC-DC step-down charging board comes in a set of 3 pieces. It adopts CC / CV constant current and constant voltage control mode specially designed for lithium battery charging. Powered by the XL4015 buck converter chip, this module can deliver stable up to 5A output current. You can adjust the charging voltage and charging current precisely through the onboard potentiometers to match different lithium battery packs such as 1S, 2S, 3S lithium-ion and LiFePO4 batteries.
The module has an integrated temperature protection system. When the internal temperature rises too high under heavy load, it will automatically reduce power or shut down to avoid burnout. It also features reverse polarity protection; if the battery is connected backward by mistake, the circuit will be protected effectively. The LED lights on the board give clear visual feedback: different light states tell you whether charging is ongoing, completed or idle.
With high conversion efficiency and low heat generation compared with linear regulators, this board is great for electronics hobbyists, lab testing and small custom charging equipment. It can also be used as an adjustable bench buck power supply for powering LED lights, small motors and other low-voltage DC devices. Note: Please set the voltage and current parameters before connecting the battery. Incorrect settings may damage the battery or the module.
