The WeMos lithium battery shield provides a means of powering your WeMos mini, or WeMos mini Pro (see item HCWEMO0002) from a single cell (3.7V) lithium battery. 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 simply 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 completed.
