Yeah. The cheapest method is to buy Dewalt 36v cordless powertool batteries then open them up to get the 10 A123 cells inside- you can split them up to make two 5s packs which is perfect for RC purposes. But like I said, the dewalt batteries are very expensive in the UK, and shipping adds a load more to the price since they arent small/light items. Still, its early days for the Li-ion technology so hopefully we will see bright things in the future- just like how Lipo has developed in a short space of time.
