Good flight battery
Pros: Plenty of power for my 20" F22, and provides approx. 5min of flight time Comes with an XT30 connector Cons: Weight was not as advertised. I purchased (4) batteries that had the following weights: Battery(1) 50.91g Battery(2) 50.85g Battery(3) 50.73g Battery(4) 51.21g So the batteries were 2.21g - 2.91g heavier than advertised. Not a huge amount over the advertised weight, however, I try to make my aircraft as light as possible so battery weight is a factor on purchase decisions. The discharge cable has nice, flexible, silicone wire, however, the balance cable has very stiff plastic insulation, some of the stiffest plastic insulation I've seen. Would I purchase them again? Yes I would, however, I gave 4 stars instead of 5 because of the cons I listed above. Keep up the great work Flite Test and Happy Flying!
