Taz, I don't question your findings and the capacity used out of the battery on each flight .... .but I certainly do question that voltage reading on your charger! That is in line with a fully charged two cell LiPo, not a LiFe battery! Are you sure your charger is operating in the LiFe mode? I would expect to see 7.2 V on the display at the end of a LiFe charge cycle.
Yes, it automatically detects the LiFe batt over the Li-Po and goes into auto mode. It always reads 8.38V when the charge cycle is complete. During charging it is around 7 to 7.5v.
Battery "B" took 23Mah earlier but I got sidetracked and forgot to snap a photo. It also read 8.38v.
