Very Interesting. Thanks for posting that Shaun
Compare the 20C Version of this cell to the 30C version of the same cell.
I believe they are the same!
They BOTH are the same size and weight. The 30C shows a few grams heavier, but those packs come with 8Ga. wires instead of 10Ga. wires.
I've suspected this for awhile now. I have an Eagletree graph of the 20C cells.
Here's how your graph and it lines up:
30C = 3.6 volt per cell average under a 71 amp load
20C = 3.59 volt per cell average under a 113 amp load
The Graph I have is a 3S pack.
Granted there are some difference in the two graphs, but pack temperature/cycle age...etc. will make results vary.
They appear to be the same cell, in size, weight and performance.
Here's the Graph. Check it out and see what you think.
