Capacity wrong, wait...my 2a gifi batteries are 15g heavier than the 1.15a OEM's. I was worried about this at first, due to the heat issues that the breeze has. OEM's gave me 11-13 mins, gifi give me 15-17 mins. Since the cost is the same, I'm pleased. Still have full capacity after more than 100 cycles a piece and breeze has not blown an esc or anything else. So I thought I would get at least a 20-minute flight out of these batteries but I did not take in account the weight of them, more power to hold-up the extra weight. So that's my my theory anyways. Curious to know the weight difference of the batteries you guys are talking about.....
