I was out flying today and an error popped up that stated there was a battery error on a battery that was at 57%. It went away as soon as it came up. I landed the quad and checked the cells and they were all ok. None were showing low voltage. I went ahead and replaced it and flew through 2 more batteries, and never seen the error again. I charged the battery that showed the error to 100% when I got home and flew it around the house and the error never showed up. Is this just a bug, a misreading, or is this an indication that this battery is on its way out? It has 13 charges and shows 96% battery life.
