Default RE: A123 Question

I wonder about balancing. If I set my charger to 1-2 amps and also to balance mode it seems to balance the batteries very quickly. Within about 10 minutes a pack is balanced. Is that normal? I am guessing that the packs are close and balancing may not take long.

Also, I am only pulling about 289-300 MAH out of four flights the last two times out to the field. That calculates out to around 75 mah per flight. Doesn't that seem low? From what everyone else was showing it should be more around 150-200 per flight. I tested this on two planes and both were running almost the same. The most mah I have drawn so far is around 100mah in a flight.

The last test I did was took both planes and flew them both four times each and both tested around 300 mah for all four flights. To me this is ridiculously good. At that rate on a 2500 mah pack I could safely fly 6 flights and not bat an eye to bother with charging. I would only be drawing around 400-600 mah for six flights.

I plan to test my 50cc before too long to see how much it uses. It would be nice if there was a slick way to bench test these A123 batteries. If we had something that could load the battery somewhat comparible to a plane in flight and then re-charge would sure make it easier to determine a baseline. There may be some tools to do that but nothing I am aware of. I suppose I get set a dummy setup up and use some servos on a receiver and emulate it to some degree.
