I found the battery here http://h1071118.hobbyshopnow.com/pro...?prod=EFLB1016 and the charger here http://www.horizonhobby.com/Products...rodID=EFLC3110. What I didn't find is much info. My guess is the plug shown on the battery should plug into the charger some place. The directions should give some insight.

The plug I see in the picture looks like the balance tap and the bare wires are for the connector of your choice.

Sorry if I'm not much help but I don't have much to go on.
