so I’m starting to get more into the quieter=better fishing crowd and want to avoid running the genny during long/peak fishing periods. currently have one battery in the house and want to add another in parallel. I also want to add a inverter to run a TV and dvd player (roughly 80 watts total), couple of questions:
1.) If I add another battery to parallel, does it need to be in the same battery group/CCA/AH?
2.) The inverter setup is going to be manually clipped onto the battery when I want to run quietly and have separate outlets. If the batteries are hooked up in parallel, can I still run the inverter and the 12 volt system (heater and lights) at the same time?
