1A 4.2V 3.7V 18650 LiPo Li-ion Lithium Battery Charger Module MPPT Solar Charge Controller SD05CRMA solar panel battery charging

Product selling points:

1: Suitable for solar power generation system

2: Constant current/constant voltage operation, with thermal regulation function, which can maximize the charging rate without the risk of overheating

3: Automatically low power consumption when the input power supply voltage is removed. Power consumption sleep mode

4: Battery overvoltage protection

5: Wiring is simple and easy to understand

6: Two options, no needle and with needle. It is convenient for customers. If there is no special welding tool, choose with pin. If you want to change the pin direction, choose without pin. Product name: MPPT solar controller 3.7V 4.2V 18650 lithium battery charging 1A charger module
