Just joined forum, lots of great advice here!
I recently bought a like-new 14.5ft Lund and need to add a trolling motor and fishfinder. I bought a 55# thrust Minn Kota and plan on wiring a dual 12v group 27 battery set up in parallel. I also bought a 3 bank 15amp Minn Kota charger and will charge both of these batteries plus the starting battery (I'm lucky to get out once a month, if that). The fishfinder is a Humminbird 798 ci Si, which says it has a 4000watts peak-to-peak power output, 500watts (RMS) output (if that makes any difference).
Question: everything is currently wired up to run off the starting battery (bilge, live well, and nav lights. No radio or anything fancy. There is a fuse panel with 4 unused fuses on the dashboard. Should I wire my fishfinder to the fuse panel and run it off the starting battery (which seems like a bad idea when I'm adding a dual 12 volt system), or use an inline 3amp fuse and wire it to the two batteries that are only feeding the trolling motor? I will be using the trolling motor on a river and will need it pretty constantly for 6hrs or so (thus the 2 battery parallel 12volt set up, instead of one battery).
Thanks!
