Modular packs

[TomTranter]

Currently a pack is simply a single set of batteries in a combination of series and parallel with two busbars both with the terminal on the left hand side. This could represent a module in a larger pack and so needs to behave and interact as part of the larger system in a self contained and modular way.

A ‘unit’ can be any of the levels
