I have a mini 2 battery that is somewhat tight when I insert it into the drone. The other 3 slide in easily. Holding it doesn’t feel any different from the others. Voltage is balanced and it has 23 cycles. Battery is 15 months old. Should I be concerned?
Have no experience with swollen batteries. Well actually I do but those were battery packs for airsoft guns , I think.
