Kanger EVOD 650mah battery, available in a range of eight exciting colours. Choose preferred colour below. The genuine EVOD is about as good as it gets with manual eGo style batteries. Regulated voltage means it always delivers 3.7 volts, even when not in a state of full charge. Most cheaper batteries will have a voltage drop-off as it gets discharged through use. The stylish flat power button is both easy on the eye and easy on the hand during use. Has both a 510 and an eGo thread, making it compatible with just about every type of atomizer tank.
