Measuring what a pack does under load, not at rest.
Measuring sag under a known load
Measure at the terminals, not at the load, or the cable becomes part of the measurement.

Voltage & sizing questions
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.
Series different batteries?
No — same model, capacity and age.
