@Madhungarian@claudius62 that is good news. The older drone batteries always do seem to work better than the newer ones. I'm no battery expert but it seems to me the newer higher capacity LiPos don't last as long; either because of lower quality or just higher density leading to more heat/faster breakdown.
My EVO II is now close to 2yrs old and the batteries still work like the day I got them so another 2yrs would be a nice surprise. The drone itself is rock solid; definitely never going to update the FW.
