Sorry I didn't get back to you sooner. Out here on Cedar Key, FL and basically took a vacation from the internet and cell phones for a few days (ahhhhhhhh....).

I run a Norcold AC/DC fridge (8 amp draw - the smaller model), house lights (some incandescent and some LED ) an AM/FM/CD stereo and occassional VHF. I can last out like that for at least 3 days. Don't run any mwave or other heavy-draw appliances. I have a small inverter for a fan in the cockpit area and charging/running the laptop. I also have a Honda 2000EI generator that can charge the whole shooting match up, as well as an 80 amp alternator on the single engine. THe Fridge is the biggest amp-sucker and it cycles 3-4 times an hour for maybe a total of 20 minutes each hour. Knowing the total probable draw on your system will give you a very good idea of the amount of time you'll have without having to charge up.

I think you;d be able to run most of your stuff on the two 29s you bought if they were dedicated to the house bank.

I also have a Blue Seas ACR (auto charging relay) that automatically keeps track of my batteries and never lets the engine bank get drawn down. I also regulates the state of charge on both banks when underway using the alternator or at the dock when plugged in to shore power. I never ever have to mess around with the battery switch since the ACR does all the switching automatically.

Thanks Randy, the house batts are isolated or combinable with the start batt. My system is fully automatic as well. Only time I would have to touch a Perko switch is to combine batts in the event the starter was low. Also have a 1150 amp jump pack for emergencies if needed.....I'll disconnect shore power and do some testing prior to heading out, then I will know exactly what to expect.........thanks again.........John
