It could be possible that the battery is flat out WORE out. You could have acell that is weak, and not giving you all the power, which in turn makes the other cells work harder.

Do you have a way to check the balance of the cells? If so, have you balanced the packs??? If they are still balanced, and still does what you describe above, hate to say it, but your battery is tired. Need to retire it.

I'm not sure I understand what you are sayin, Kiwi???

Ambient temp has something to do with batteries and how long they perform. Lipos are best when warm. Not hot, not cold, but warm. During the summertime, ambient air temp, sometimes is a little too hot. Just really depends on where you live..
