I've been on the fence between the 920 and 721. I'm watching you live at murray on one screen, and watching this video on the other. After counting somewhere around 15 rods on your front deck, and you still having room, I believe I'm sold on the 721
Yes and no, I have a switch in between them to be able to select which one powers my electronics. The PP charge takes care of the 3 trolling batteries and the agm crank battery and we spliced in a small single bank noco onboard charger that takes care of that stand alone lithium. Additionally there is a DC to DC charger to top off that stand alone battery when the engine is running
