So I've got some 1400mAh 4s batteries (Turnigy Multistar) that I have had a great time with, and I definitely intend on keeping them as my main battery. However, I was thinking of getting one or two batteries with high capacity for longer less-speedy flights (mostly just to cruise around). So nothing with a high C rating, possibly just a 3S. Does anybody have any recommendations for that sort of thing? There are a lot of batteries out there and I haven't really seen that sort of thing commonly implemented for racing drones. Any recommendations?
