So far so good. I found that these are the best lipo you could buy. Ovonic 4s 1300mah is perfectly sized, they seem to keep getting better while maintaining the same size. Noticeably better than last year's 100c. Crazy punch-out power with almost no sag. I noticed some at the end of the charge. To be expected. I couldn't be happier with the size. Seems a hair longer but not as tall. Feels roughly the same weight.
I don't try any other brands because Ovonic has been so well to me over the years. Still flying my old 75c packs two years later. To be honest, once you try this it will be hard to use your old batteries.
