I have 2 gel batteries @ 225AH each in parralel as a house bank, and a dedicated starting battery. Our power needs are moderate. Mainly refrigeration,
GPS Chartplotter, cabin and
anchor lights, and the
inverter for DVD's. All of which will be in more demand when we go cruising for 6 months in the Fall.
In addition to the alternator upgrade, I'm installing a Link 10 for monitoring.
