Been over 6 weeks since I used the M600 Pro, took it out today, charging batteries and getting ready to fly tomorrow. Noticed one of the batteries has no lights whatsoever. Same battery that had a problem during software upgrade on the aircraft before. I was advised back then to plug it in the bird and redo the software upgrade. It worked but now, nothing. Any ideas? I attempted to charge it but, no life.

Sorry to hear that, if the battery cannot be charged or even turned on, it is recommended to send in for evaluation, please contact our support to start a ticket here: https://www.dji.com/support?site=brandsite&from=nav
