I own an Optima Blue Top Dual Purpose Battery (D34M me thinks). I actually own two. I use one for solely my trolling motor(Endura 55) and other one for my depthfinder, electric start on my 9.9 mercury, and CMC tilt n trim jackplate. Is it possible to run a smaller thrust trolling motor on that one battery i use for my df, CMC, and Merc so I can cut down on weight to help plane my boat or would it be too many applications for that one battery? That Endura eats up a lot of battery.
