Deep cycle batterys, solar, amp-hours. question.

Certainly worth thinking about. If there does exist a way to use only one 6v battery to achieve 12 or 14v, all will be well. Using both batteries does seem daunting. It still seems worth trying out since the investment is mostly time. Also, if my driving is mostly flat and I'm not dealing with any continental divides on my daily commute, I expect that a 13% weight penalty might not reflect a 13% loss in efficiency.
