Yes thats the battery! Seems like a nice battery. At the moment I do not have a voltage regulator installed. A friend of mine has been flying without one using a life bat. on the DLE ignition for over a year now with out any problems. I may buy one for security when she's ready for flight. As far as the DLE manifold (aka the muffler) goes I dont feel as if it is much louder compared to other pitts style mufflers, I was acually surprised by this. But pitts muffler looks alot nicer!
