Hey guys, I picked up a P2 with H4-3D used today. Everything on it seems great with one exception. It came with 4 batteries and they all discharge within about 3 minutes. As soon as I get it maybe 20 feet off the ground the P2 starts flashing red and the iOSD shows voltage dipping to ~10.5, then it starts to descend and I can see battery life dropping about 1%/3seconds Here's the stats from them in PT2: Battery 1: Full Capacity: 5153 Percentage of Charge: 97% Discharge times: 16 C1 voltage: 4176 C2 voltage: 4176 C3 voltage: 4176 Battery 2: Full Capacity: 4800 Percentage of Charge: 5% Discharge times: 20 C1 voltage: 3831 C2 voltage: 3847 C3 voltage: 3818 Battery 3: Full Capacity: 5200 Percentage of Charge: 64% Discharge times: 7 C1 voltage: 3926 C2 voltage: 3936 C3 voltage: 3946 Battery 4: Full Capacity: 4870 Percentage of Charge: 59% Discharge times: 25 C1 voltage: 3905 C2 voltage: 3911 C3 voltage: 3918 Looks like the cells are fairly balanced.... yet they all exhibit the same rate of drain. Any suggestions?
