2S Zippy 1100 Lifepo4 useabale Mah's?

Does anyone know how many mah's I can safely take out of a 2S 1100 lifepo4 pack?

Right now If I fly my Trex 550 pretty hard at 2550 in idle up 2, I'm putting back in 195 Mahs after 2 flights. The question is ...... how many more flights can I get? What is the most amount of Mah's that can be taken from the pack before things become too risky to fly again?

I don't trust my multimeter. It showed 2.96 per cell after 2 flights but when I put it on the charger the charger said I had 3.3V per cell left.

I'm just trying to figure out my limit on this pack. Its no problem to charge again after 2 flights but if I don't need too I'd go another 2.

Follow the 30% rule for the first ~20 cycles of a LiFePO4 pack, after that you're supposed to be able to drain them completely safely. However, I wouldn't recommend it, you don't want your pack to die mid-flight

You really cannot load test an A123 or LiFE pack. If you are using approx 200mAh in 2 flights, you can sefely fly 6 flights and be at 50% pack capacity.
