Li-ion Charge Module 1A 4.2V 3.7V 18650 LiPo Lithium Charger MPPT Solar Controller
- Lithium charger for solar powered system.
- Precharge adjustment for restoring deep discharge batteries and minimize heat dissipation at the initial charging stage.
- Maximum charging current/output current is 1A, but you can change the current by changing the value of the R1 resistor.
- Power supply voltage DC 4.4-6V, charging output voltage DC 4.2V.
- Automatically adjust the charging current according to the output capacity of the input power supply.
