Aspire has some very good 18350 cells, bot how about their low capacity 18650 cell?

The discharge curve matches fairly well and capacity is constant up to at least 30A, but the 30A curve looks to be at the limit for the cell.

At 30A the cell gets very hot.

[size=+3]Conclusion[/size]

The capacity on this battery is rather low, but the performance up to 20A is good, 30A is at the limit.
