Thanks for that info. I just purchased a used P3P with 1.5 on it, and on its maiden flight with a perfectly good battery, the voltages displayed for the cells were all over the place, varying by as much as .25V, and lower than I have ever seen before, resulting in speed throttling on the return! I thought it was the battery having not been topped off that day, but with auto discharge set to 10 days, I had fully topped it off the day before, so that made no sense! Sounds like I need to get off that firmware immediately!
