These Ego's run on Lithium Polymer batteries (LiPo) which provide a terrific form factor while making required true power available. These really put out up to 6v and hold it. Testing has shown us accuracy within 0.02v right up until it shuts itself down for recharging. Testing has also shown a true capability of 9W and 1.5A before limiting kicks in. Try that with an ordinary Ego...This is true big battery mod performance!!!
