Short answers to the ones that come up most.

How do I choose a voltage?

Set by the equipment — 12V small loads, 24V light traction, 48V storage and traction.

How do I work out runtime?

Ah x V = Wh, divided by the real load, minus losses.

Why 12.8V?

Four 3.2V LFP cells in series.

What is C-rate?

Current relative to capacity.
