[QUOTE="gnappi, post: 455877, member: 22374"] I should clarify my battery weight / Ah issues above. My larger group 27 92Ah battery is 63 pounds, that along with one spare 35Ah battery at 21 lbs is 84 pounds. My three 35Ah cells are a total of 63 lbs saving me 21 pounds for a lighter boat, easier weight distribution and a bit more run time (3x35Ah=105Ah vs. 92Ah) capacity. My initial Q was more for my friend who will have only one main cell for the TM and the 35Ah for the instruments. When the main cell runs low he wants to be able to switch without moving batteries or re-attaching them separately. Hence the Q about a shared / common ground setup. So I guess input from others who are running a similar setup my friend has will have suggestions on how they switch batteries. [/QUOTE]
