Recieved a new OptiPower 6S 2700mah pack yesterday... what voltages should i expect to see in each cell from new? Reason i ask is the pack i recieved the week before was half charged, around the 48% fuel mark on the 10S. The new one showed 20% fuel and around 3.82v per cell which is a bit too close for me. Should i send it back or will this be acceptable? Its now fully charged and ready to fly in the 500EFL today. I will be keeping an eye on it but just wondering what you guys think? Im concerned because there is such a diffrence between the way both new packs arrived. They also came from 2 diffrent shops.
