The idea is this: create a battery managent board for devices with many expensive batteries. Eg: electric vehicles.
A typical electric vehicle will have between 8 and 50 batteries worth as much as the rest of the vehicle.
So the concept is a microcontroller to run each board (one per battery) and solder bridge jumpers to select battery chemistry, running off the battery it is attatched to. These batteries are 3.4 to 12v nominally so a low power chip should do as long as it is protected from higher volages and noise.
