Hi! I bought my Phantom 3 Adv new about 8 years ago. The RC never had issues. I don't fly that often. Seems about a year ago my RC would start to charge, I'd get a few flashing lights, they'd go out and would only have 2 or 3 lights on. I'll plug it back in, it'll charge for a few minutes and stop. I wouldn't be surprised if the batteries were bad after this many years but I've read that it might not be the batteries. I can't find the actual battery percentage in the DJI Go app (ver 3.1) although seems I remember seeing it just yesterday? I've tried resetting the RC (2 back buttons and the rec button, beeped). Any ideas? Thanks in advance.
