Trustfire TR10440 "600 mah" battery for the Joye Stick V3* - These batteries will fit the Joye Stick V3, built in protection PCB adds about 1-2 mm of length to these. (They fit perfectly in the stick and can be charged inside, but dont fit the wall charger that comes with the V3 kit.) These will most likely fit any other "slide" operated battery chargers. This battery offers more protection and a longer battery life that the factory batteries supplied with the kit. Pick a few up to have spares for your V3 or any other mod that takes 10440 protected batteries**. Price is per battery.

**I can only claim that these Trustfire TR10440 protected batteries will fit the V3, I have NOT tried these in other mods, please make sure your mod can fit protected batteries before purchase.
