This is a
Solar Power Management Module for charging a 3.7V Li-Ion / Lipo batteries. The
module accepts solar voltages from DC 4.4-6.5V and converts them into a
charging voltage of 4.2V. The maximum continuous output current is 1A. This can
be adjusted by changing the R1 resistor. The integrated overcharge protection
and automatic sleep mode protects and increases the lifespan of your battery.
If you are using a solar panel with a voltage higher than 6V, you can use our
DC-DC Step Down Module to reduce the voltage.
