Purecrea MPPT SD05CRMA Solar Charge Controller for Li-Ion / Lipo Batteries

This is a solar power management module for charging a 3.7V Li-Ion / Lipo battery. The module accepts solar voltages from 4.4-6.5V and converts them into a charging voltage of 4.2V. The maximum continuous output current is 1A and can be adjusted by changing the R1 resistor. The built-in overcharge protection and automatic sleep mode protect and extend the lifespan of your battery. If you use a solar panel with a higher voltage than 6V, you can step down the voltage using a DC-DC step-down module.
