i am happy to inform all of you that the battery works pretty well it flew great my plane is flying wing speedster pro from vortex-rc ....
as compared to 2200 mah lipo it is light weight and small size and of 2450mah
one of the only flaw is its c rating is not parallel to lipo it delivers about 75-80 % of a 20c-30c lipo
but still it is good enough for flying and best for fpv
enjoy make diy batteries from laptop lipo and save money
