Here is the initial plan for all the components. The pack resides in the bottom because it has the most weight and that'll stabilize things. The yellow blocks are the AC power supplies. The smaller red blocks are the dc/dc converters for the charging side of things. The bigger blue block is the output dc/dc converter. Finally the smaller darker blue block is the low voltage disconnect.
There is still obviously work to do on it (handles, power button, etc), but its getting closer. I'm still debating on adding a fan to this thing.
