I purchased this battery because it was so cheap compared to the other a123 batteries that I purchased. I put this battery in a 1/4 scale clipped wing cub with all standard servos and flew about a 10 minute flight. I charged after the first flight and it only used 68 milliamps, Wow is all I can say. I will purchase more of these in the future, maybe one of the smaller packs because this one is longer than any NiCad pack and I could fly for a week with the 2500. Very happy will buy again.. Thanks
