      The house battery I am getting with my Capri camper is a Interstate AGM deep cycle battery. What I would like to know is do you feel this is enough power for what I am getting. The camper will come with:

      12 Volt Fantastic Fan
      Multiple interior 110v outlets plus single 12v & dual USB charging station
      Interior & exterior LED lighting plus bright porch light
      Combination LP & CO alarm, plus smoke alarm
      Roof Mount Air Conditioner
      Microwave 0.9 c.f.
      12 NovaKool Refrigerator 2.4 c.f.
      2 Burner Cooktop
      32″ Digital HD Flat ScreenT.V.
      Catalytic Propane Heater

      Here is the information that Capri sent me on my battery and electric system:

      Probably won’t be able to run the air for sure and maybe not the microwave.

      the rest you may be ok if you use conservatively,

      I like 2 100ah telecommunication batteries and 66 watt solar panel, will run the furnace and fridge in the winter with little sunshine. Never use a microwave or air at all.

      Coly, the old saying “more is better” certainly applies to battery’s. Providing you have can carry the weight and have the room I would double up. Personally, I am not an inter state fan so that would change immediately. For those of you on a budget Walmart offers the Everstart brand. There 29 series max deep cycle battery has proven it’s worth in my bass boat. The battery comes with a two year warranty and the two that I had were still good after 6 years. For 100 bucks, I think it’s one of the best deals out there.
      On a slightly different note, I recently noticed Everstart is also producing a large agm battery with 900 CCA and a non prorated 5 year warranty, all for 150. For that price with those numbers I will probably use them to replace the oem units that came with my diesel truck when the time right.

      I’m probably confused, but I don’t see an inverter listed in this rig so AC loads are not really relevant to battery size directly and when on shorepower, the converter will easily handle these DC loads. Seems like fantastic fan and fridge would be the “power pigs” when dry camped.

      Battery brands are always open to discussion. I use a couple of golf cart six-volt AGMs in series from Sam’s club, but again plenty of room to argue for others. One thing for sure when dry camped, there is never an argument against having more. Kind of depends on how this rig will be used, but I bet most folks would do fine with things as they are. Might want to give it try first before making changes. Just my thought. 🙂

      Thanks for all the advice. I don’t have an inverter but will probably get a Honda generator to run the AC. I was also thinking about getting solar panels.

      Coly,
      Again just my thought, but if you are going to carry a genny, I would not invest in solar. It is pricey and seems like it might be overkill. We have solar on our fifth wheel because it sits stores at the beach and the solar maintains the batteries in storage. In our truck camper we carry a Yamaha 2000 which easily handles our AC and battery charging requirements.

      If you do go the genny route please invest in something quiet. I believe those who buy the cheapest loudest contractor models should be tied to an ant hill. 🙂

      Not trying to start an argument here with those who favor sun power, but a genny never cares where you are parked and what the weather is doing. 🙂

      Take a look at the Champion line of inverter style generators before you lay down extra dollars for big names. Champion will give more power, less cost and comparable db levels.

      Recommended by others on several websites also.

      If you are plugged in, the battery is irrelevant.

      If you are not plugged in, you can only run the 12V stuff without an inverter (so no AC and no microwave).

      100 amp hours should get you through one night with the fridge, some fan or furnace use, lights and some TV.

      Not sure how good the WFCO charger is. Getting the battery to full charge is very important and many of the converter/chargers do not do a good job. This site has an article on the Progressive Dynamics converter charger.

      As a point of reference, I have 235 Amp Hours of battery and overnight with temperatures in the 30s using lights, some furnace, propane fridge (uses much less than compressor fridge) water pump, Ipod speakers, I wake with about 90% batteries left. This is really 20% of the capacity used since you should only discharge to 50%. For your 100 Amp hours, this would be more like 40% capacity, but I bet the compressor fridge alone would take 20% of your capacity or more.

      If you are plugged in all the time, it’s a non-issue. If you plan to live overnight on the batteries, invest in a Trimetric battery monitor so you know the state of charge and don’t kill your batteries.

      I have two batteries that have 100 amp hours each and the last two nights I stayed in my camper with just the batteries and only ran my fridge and some lights and was fine.

      Odyssey Extreme AGM Grp 31 x 2. You can find them for under $400 online shipped. I have one I have had for 15 years and it’s still working great.
