Bottom Line: This is a poor performing cell that I am rating at 17A/2400mAh. While the wrap does list both the continuous and pulse ratings, normally a very good thing, its claimed 30A continuous rating is wildly exaggerated. Its high internal resistance, nearly double that of most good 20A cells, means that it suffers from considerable voltage sag. At 25A continuous it got hot enough to boil water and at its claimed 30A continuous rating its voltage quickly collapsed. Its pulse performance was significantly below that of most 15A-20A cells. Its appearance doesn’t match any battery I’ve tested so far.
