Skip to 7m 43s for the drop in battery.

Has this happened to anyone else? Anyone know what happened? I've attached a chart of the battery cell voltages during the flight. Minus the flat spots when signal was lost, does it look ok?

FWIW.... and slightly tangential, I had a similar issue with an 8 month old battery for my M2P. Managed to lad safely at home point. When I removed the battery from the bird there was a mild bulging of the bottom of the battery. Didn’t look further. Relegated it to ground work only.

That battery wouldn't happen to have a production date 8/2018 or older, would it? There's several threads on M2 swelling batteries, but one main one in particular.

Yep... read them all, literally.
The battery that failed (swelled) was produced in 2/2019... it had over 150 hrs of use... much of it in ambient temps of 100-102 degrees.

If you've owned it less than 6 months it's under warranty.

Unless you meant 2/2018, it is barely over 6 months old, or not even since it can be as much as 2 months from production to sold.

It is over 6 month since activated.
