I would call them and ask if they are suitable for Multi-copter usage. They have been very forthcoming. Some of their high C batteries which sound like they would be great for our type of usage they will tell you are not meant for the types of loading that we do to them. Better suited for RC cars, etc.
Good Question, this topic is being discussed Here. http://www.rcgroups.com/forums/showthread.php?t=1677105&page=342#post24115308. Bottom of page 342. In any event these batteries seem super expensive. You should be able to get quality lipos in the 5000 mah range for about 100 bucks a pop. But I'm not starting that debate.
