Chris, it's hard to see the numbers on the graph so could you post several current/voltage points at various points (preferably not at the very beginning or end)?

Ideally, it would be nice to have the voltage/current immediately before a current spike, and then the voltage/current during a spike.

I'd like to calculate pack internal resistance at various current levels. This will give up an inkling of what to expect at various loads. If we see IR increase dramatically at X amps, it means the pack is getting close to its max discharge value so we can then use that as the "true" C rate.

Could you also confirm cell count and wire gauge and length from battery to ESC. Normal 12GA wire can introduce substantial voltage drop at 178A and would be nice to take that into consideration.
