Health drone is showing a deviation that is progressively getting worse. Battery is 4 months old with 32 charges. Can I RMA?

I would think so. the warranty says 6 months on batteries ! go for it !

I'm having the same problem with one of my batteries. Approx. same age and charges. Getting worse.

IF go app does not report a problem, not sure if they will do it.. where did u buy the battery?
Better chance replacing it there?

Are these stock or not?
Are you discharging them when not in use?
Are stopping the flight with at least 10% to 15%?  etc...

You are within the battery's warranty, so you can look into getting a RMA. Just to clarify, have you tried performing a deep discharge/recharge to see if it helps alleviate the issue? Did you notice this after a firmware update, hard landing or long term storage?

Jaime it shows a bad cell from inception, I recently did a deep discharge, never had a hard landing or store them for long, I fly then store for a few days.

Sounds to me like u certainly should contact dji support asap and get an rma.

Do you also fly agressively or end up fighting the wind often? Flying aggressively or having a 'lead finger', sort of speak, it could cause the battery to dip drastically in voltage causing a false error. If that's not the case, then you would want to look into getting a RMA for replacement like Phantomski mentioned.

I've requested a RMA, still waiting. I fly the same with all batteries I own. All were purchased with the P4 from DJI directly. I rotate usage and adhere to storage parameters.

I don't know where you live, but I have had mine since Xmas so all of my flying has been during cold weather.
I know this could lead to battery problems.  Even a heated battery can get very cold 300 feet up in the air.
I wonder if DJI uses info like that from flight records on the battery ?Anyone know that one ?
