Fairly new P3A. Only had about 15 flights. I noticed today the battery cell variance is .04v. The first cell is usually down from the others by .03 or .04. When I saw this today I got worried and landed right away. I have searched on here and elsewhere and found a few references. Some recommend .03 is the limit? Others say .02 or .03 is normal. Right now the cells read :4.27, 4.31, 4.31, 4.30 I have been only going down to 50% power each flight and the battery life is still reading 100%. Should I be worried? continue to fly? What would you do. Thanks to all on here for your experience and advice.
