I don;t knwo which version of ABF U using, but the older version sticker stated as 2200mah 20c is not wat it is, it is actually only 1800mah 18c. I got it for $18 each.
I have 3ABF, 4Zippy & 2 outrage. None have caused any problem. all 9 packs adds up to atleast 300 cycles. Heli don't fly as it should can cause by many problem, mechanical error, electronic error, setup error etc..Lipo puffing or lose of punch and capacity can cause by mishandling i.e: discharge it more then 3.75v per cell, high room temperature, charge it right after a flight, lousy charger etc...All in all, $154 for 7 chinese lipos and $120 for 2 outrage, without 7 chinese lipo wat makes u think I can achieve 300 packs today with such low cost?
It is safe to discharge lipos down to 3.0v per cell. 3.7v/cell is the nominal voltage of lipos. When you get down below 3v/cell is when you start to lose batteries. Also, don't charge above 4.2v/cell.
