I have a MP battery I purchased in August 2017- as of today I have charged it 3 times.

Last two times it gave me a battery error- land now- middle cell is very low-
SO is ther any warrante after only 3 charges??  I read some where- like 100
charges or 1 year- but cant find that now--

Did the battery sit for a long period of time.

Hi there, the warranty of Mavic Pro battery is 6 months and charge cycle should be less than 200 times. It is recommended to send in if battery is still in warranty period.

That was my immediate thought too, 3 charges in 5 months. He let the battery discharge to low and killed a cell. I have had other RC batteries die on me because I forgot the charge them every few months.

Thats useful info - thanks for posting

The battery might still have a use as a power bank using the adaptor DJI provide with the Combi pack. There might be a chance its performance improves for non-drone purposes, like making sure your go4 device is fully charged so it does not draw a charge current from the controller, initially.

Good information for a rookie like me.

Thank You- I did and and answered all questions-  got form to fill out- spent a whole day-off and on- trying to send flight records to cloud- downloaded 90% then keep disconnecting-

SO I gave up- and trashed the battery-

What I don't understand I had two green lights on while winter passed and yet it destroyed one cell- in the middle- should I store the batteries in a more charged condition??

If the battery will be idled for a long time, fully discharge and re-charge is recommended to ensure the battery liveness.

Sorry for the late response due to the holiday. The recommended battery level is 40%-65%. The battery will be discharged automatically according to the settings in APP.
