I've been considering the battery capacity/flight time/weight problem. While working my way through far too many threads on the subject I came across a few batteries of note.
This one from a sketchy looking website that is not LiPo:
4S 14.8V 10000MAH 15C nano lithium battery 770g for RC airplane
This one from a sketchy site that is lipo:
Lipo battery 11.1v 10000 mAh 25C
and this one from the less sketchy maxamps:
LiPo 11,000 3-cell 11.1v Battery Pack
Why isn't everyone using these? It seems like you double your capacity for much less than double the weight. The C value is low but if one is interested in flight time you don't need 50C, right?
Is cost the only reason no one is using these or is there something else going on?
