I think that installed or not depends on how hard it is to get to your batteries. Mine are in the bilge close together under the transom, PIA to get to.
I did the same NOCO charger and plug as Coastboater. Install was easy. Happy so far. I'm curious to see how long it will take to fully recharge a battery at 5A after a day of running the 30 Amp potpuller pulling 35lb shrimp pots 300ft. I'm considering installing a bluetooth battery monitor like the Victron in our motorhome.
