| You really don't want to use emoli batteries, they can't take more than about 15C discharge. If you want to use something other than Lipos, use A123 cells. These cells can take a lot of abuse and can be completely discharged, removed from the heli and charged at 10 amps. and don't have a lot of voltage drop. If you have the TPPacks.com CF frame conversion that will allow for A123 packs, you can use two 10S packs in parallel (10S2P). This would give you 4400 mah @ 30v. The resting voltage for an A123 cell is 3.6v but drops to 3v when a load is applied and then will drop to around 2.3v. A lot of guys set the normal and idleup 1 throttle curve to say 80 and idleup 2 to 100, depending of coarse on how the heli is geared but the idea here to maintain HS so when the cells start to go down you can go to idleup 2.
There are a lot of threads here and on rcgroups about A123 cells and emolis, if you don't have any experience with either I would suggest doing some reading before trying either one, it might save you some money down the road. Simple things like charging and soldering leads and cells together.
Here is one thread.
