    Just finished building a portable 2kwh 1500W 120VAC inverter project. Think of it like a gas-less generator. See the imgur gallery below for build pictures, and the github for the photon code and a schematic/circuit drawing. Big thanks to Kyle at four-forty.comwho supplied the current sensor...

    New cell suppliers to the US?
