What size battery are you running? If you are using the stock 1800 20C, your flight time should not be over 7 minutes. In a normal hover with stock parts, you will burn up 170-200 mah per minute. If you are flying 10 minutes a flight, even at normal manuevers, you are doing damage to the battery by running it below 20% remaining.
Buy a BC-6 Charger from Bantam and you will be able to track these numbers.

9-10min just hovering then lvc would kick in ,voltage was 10.4 at that point.remember only started having problems after crash!!! problems aren't with charging the batteries, i also have an ice charger that's very good...

well iv been running 9-10 min on mine with no probles also not draining to much as to hurt them the ESC 50% cut when voltage reaches right before that point just have to listen or use the timer set to 8-9 min
all should be just fine
in other terms a friend of mine also said his goes to cut down at 5 min and he noticed i flew much loger than him so it may be the esc is progframed diffrent or stock charger
not sure whay the diffrence

on the stock battery I get 7 min max and it shuts down so I set the timer to 6 mins. On the loong-max 2250's I'm getting 9 mins so far and still have more left before hitting 80%
