i guess got lucky ........ I have two of them and they work fine. Well my second DJI battery Serial No. 830 is dead and has been giving me
trouble ever since I bought the thing at 65% it tells the software it is time to land.... :@
Great way to take out the battery, thanks for sharing. I came across another method on youtube that recommended applying a small amount of grease on the battery. That method is not for me.
