I just installed my first electric rigger, a captians pak. I plan on adding a 2nd battery for it and electronics. I currently have an extra marine battery, here are the specs.1000cca , 115 amps hr. 180 reserve.... Is this ok for 1 big john electric and 1 gps and 1 fishfinder?Will this hold up for all day fishing? I will be running a 12lb weight.I would appreciate any suggestions, Im keeping a matching battery for main motor and running lights, I just have no idea how much the power captians pak will need ?
