The KiCaD project can be accessed here.The Protected Battery Board can be used with other hardware: The boards have a Molex Pico-Lock Connector with 5 pins. You can get ready-made cables for those at DigiKey (e.g. Molex 151320502). Pin 1 and 5 are plus and minus, the pins in-between are intended as measuring and balancing conduits (each connected to the positive pole of a cell), but do not need to be used. Important: The whole charging/balancing technology is located on the motherboard. But it would be possible to charge the cells separately with a charger (e.g. Nitecore), or to add a current-limited 14.4V source for charging (4*3.6V). The LiFePO4 batteries don't need special charging technology (in contrast to Li-ion!).
