Got these batteries due to the great price and weight, but the batteries aren't 5500 mAh, more like 3500 mAh. Charging at 5.5 amps, 1c, these batteries are fully charged in 15 minutes with a starting voltage of 3.80 or so volts per cell. My other 5500 mAh batteries take 40 minutes at the same charge rates. Flight time in an 80mm EDF is 3 minutes of mixed throddle flying, and the cells read 3.78 on landing, compared to my other batteries getting 4:30, and reading 3.80 with the same style of flying. Returning for a refund.
