Trying to figure it out - but looks like the configured capacity is an input factor too, i've had a few full cycles and i'm still seeing crazy capacity jumps.

I've got 2 packs in parallel, I didnt fully test the new pack for capacity - so took the manufacturers word (304Ah) for it & it looks to be "bigger" by a good chunk.
Here's the output - ignore the little dip in capacity, as i changed the total capacity of the battery in the config.

Is this purely from under configuring the battery capacity in the BMS?

Old BMS which is in parallel for reference...
