Exactly what @SimosMCmuffin said. Aaaand,
All I’ve read suggests that although not directly related, nor associated with, or measurably linked to each other, “C-rating” of a battery indicates (but does not reflect) what you might be able to expect in terms of internal resistance. I.E: A small pack with a REALLY high C-rating, like a 5000mAh 90C pack, probably tests low on IR values, whereas a 8Ah 10C pack will drift in per-cell-voltage and sag, more than the smaller, more ‘capable’ battery.
My pack, which is a 22Ah 25c 12S lipo can supposedly do (22*25)= 550A continuous (wtf, right??). Doesn’t mean I can actually pull 550A without causing an inferno of some-magnitude. It does however, imply that this pack is going to perform predictably well under normal to extreme (lol) demand
But again, low C-rating per mAh of capacity doesn’t equate to anything, it just proposes a class. Real world performance will likely be better in the longrun with higher levels of quality, however suggestive and biased their metrics may be!
Build a board after the battery, and regret not
