I'm finally recovering from pneumonia so time to push this project forward.

First of all I'd like to thank all my followers who gave skulls (and thus money) during the first Hackaday Prize phase, and also Hackaday for selecting this project as a first round finalist! The money will be used to buy components and pay the CM to build the boards. First components have started to come in, here are 300 charge chips (J version) that will be used on the LiFePO4wered/USB base boards.

I'm doing a new proto build for the LiFePO4wered/Pi 5V version with some improvements to the layout. I have decided that my first build will probably be the 5V version. This will result in less run time, but nobody will be able to find fault with the voltage not being in spec. I've also decided to use proper 5V instead of 4.75V for the same reason.
