Related note, loaned out my TM Mac10 which runs the 900mah Lipo's like my other AEP's. Person said they got roughly 20-25 mags (65rnds/ea) before the gun stopped firing. Battery was still at 3.1v's a cell so still in the safe zone. Battery may not have been 100% charged before hand though.
I loaned mine out also and they ran it also til it stopped (~6hrs of gameplay). The cells were below the safe zone, fortunately the battery wasnt damaged but im sure the life has been prematurely shortened.
