Lithium battery

Thanks guys for the comments. What got me going on batteries was the fact that I weighed the plane and did the CG calculations yesterday. Came in at 649.8 lbs with an empty weight CG of 13.46. When I was calculating most aft CG, I ended up going back to about 14.9" when I got to 1200 lbs total weight. Just behind the rear limit of 14.78". My battery, a lawn tractor battery was back on the shelf about 24" behind the seat. Got to thinking that if I went with a lithium battery, I would drop at least 10-12 lbs, and the CG would move forward a fair amount. For now I'm going to move the battery forward to as close to the seat as I can fit it, and that will move the CG just far enough that I can load to 1200 lbs and still be in the CG envelope. I do have room in front of the panel for a battery, and thought about going there, but it gets tight with the battery I have. Did some searching on here, and guys like the Odyssey 680, but it's just as heavy as the one I have and almost the same size. Has anyone been using the Odyssey 545 with an 80 HP Rotax? it's a bit lighter, and would fit better in front of the panel. Thanks JImChuk

PS here is a picture from last night and the panel from a few days ago. Right side of panel is empty for a 7" tablet to set there.
