Battery help please.

[Mactab]

On doing some initial testing with the inspire today ( delivered Wednesday with updated firmware already installed)I encountered a couple of glitches. I am using the IPad Air 2 with the IOS 9.2 app.
1) the RTH function kicked in a couple of times for no apparent reason.
2) the battery went from 75% to 5% critical warning in a split second.
Thankfully I am literally flying no further then 50' away over my garden so I was able to land immediately.

Any thoughts from those with experience?
Many thanks

Sounds like you need a new battery.. I would contact support but possibly try to update the Inspire one last time as the Intelligent Flight Battery firmware may be the issue

Your battery seems to have a dead cell or at least to be severely imbalanced. Probably needs a warranty swap.

yes that number 4 cell did look as though there was a problem.
I'll get the battery replaced as one cannot be too careful.
Thank you Brian and Kilrah
