Compared to my other 2s 450mah which are only rated at 30c these are terrible. The others offer 6 minute flight time on 1.9" props 1103 7800kv motors and these give barely 2 minutes and get hot where the 30c stay cool. I think these are mislabeled. Each cell has same dimensions as some 240mah 1s packs I have so I think these probably are just that: 2 stacked 250mah 20c cells and not 450mah 60c as labeled. DO NOT BUY THESE!
