I have ordered 2 Optima D34M batteries for my MK Terrova 55# TM. It is a 12 volt system. They are the only batteries I have found small enough that I can put two of them in my battery compartment. I plan to wire both batteries in parallel (red to red - blk to blk) to keep the output at 12 volts. Is there any reason this would not work? I assume that charging one battery will charge both of them? Any thoughts on this subject would be appreciated.
