WeMos D1 mini lithium battery shield

Description: 

The WeMos D1 mini lithium battery shield provides a means of powering your mini or mini Pro from a single cell (3.7V) Li-Po The shield contains a DC-DC converter to step-up the batteries 3.7V to 5V, supplying your WeMos mini and shields with up to 1A of power.

When the battery is depleted, plug the shield into a USB power source using a mini USB cable, and it will automatically recharge the battery. Two LEDs on the shield indicate when the battery is charging and when charging has been completed.

The shield has an extra USB connection for charging the Li-ion/Li-Po battery(with JST-PH 2.0mm connector) and can be set to 500mA or 1000mA charging current. The TP5400 charging chip also offers Undervoltage protection, and therefore this shield can also be used with Li-ion/Li-Po batteries that do not have a protection circuit.
