I did a factory reset and battery calibration, that solved the issue for 2 of the batteries, the third is still giving me the warning. So, I guess it wasn’t just that all 3 were suddenly duds. I have ordered a battery tool so yes, that will be helpful. Even though I don’t want to throw more money at the solo, I probably will get a battery mod because even though the solo is a total pain in the ass, for some reason I still like it. For the most part I have moved on to Mavics, which are way less of a headache to deal with but the restrictions of DJI and the power they hold over everything, I can’t ever be 100% a believer in their products.. more like a hostage. I wasn’t trying to say you don’t know what you are talking about but just the idea of 3 batteries working fine the week before and then after upgrading, they barely fly just didn’t make sense. Sure, they may be losing life but that shouldn’t render them all instantly useless. If I had a Nissan Leaf and it was driving fine with battery power, then after going into the dealership to get a software update it could only drive 200 ft before dying.. would you think “wow, my battery is bad” or would you be thinking maybe something is up with the update Nissan just installed? I don’t know many people who would assume it was just a unfortunate coincidence.
