    After much research and testing of the weird behavior of my P2V
    - inability to increase altitude (even when full throttle up)
    - at times varying drops in altitude without any explanation

    Found that the above was only happening while using 2 of 4 batteries, the same 2 batteries that are slightly swollen in the silver covering.
    These batteries have 95 and 96% life left, and have only been charged 15 times each.

    Has anyone else experienced the same swollen batteries? Or Performance issues caused by bad batteries?

    More importantly, what is the DJI battery warranty/exchange policy?

    Also, is there a way to determine the manufacture date of a battery from the serial number?
