I have a few 4 Cell 5000mah batteries at the moment and I am new to all this fancy battery charging.

My Hexacopter tells me when the battery is low, and the charger tells me in mah how much it has put back into the battery, at the moment I use about 3000mah for a 7-8 minute flight, how far can I push these LiPo Batteries before I start to damage the thing?

Cheers

Cris
