The discharge curves looks good, they track fairly well and capacity is fairly constant independent of load.

Even at 30A the cell do not get too hot, probably because the discharge time is fairly short.

Well, the capacity is REALLY low for 2018. Maybe somebody will find it to be a useful cell.

EDIT: I just looked at this cell in the comparator next to top cells that are popular around here. This cell holds it’s own, especially at the 30A test!

May be OK, but the 2400 mAh variant is simply better.

Thanks HKJ!
