The battery kit came in! Included were a 5.5V 320mA solar cell, a 4,400 mAh lithium battery (I opted for the slightly larger size for maximum charging capabilities), the USB boosting circuit, and the battery Charge Controller Board (regulates power flow into the batteries to prevent the volatile lithium from blowing up, also allows mini-USB charging input). In addition, the kit comes with a DC plug and wires to solder together all the components. Here's the DC plug and wire (with 2.5mm female plug attached) and the panel in the background:
After several hours of youtubing soldering how-to videos and practice (lots of practice!) on scrap pieces of wire, I soldered everything together. The completed circuit:
The boosting circuit board had an additional bright white LED that's controlled by a tiny switch on the side. It won't work while the board is on "charging" mode however, which is when a dim red LED turns on. Maybe there's some way to incorporate the lights and the switch into the design?
