It is a superior charger, therefore Airstream will continue to use it.

There is a lot of disagreement about both those statements. Even a cheap Sam's Club charger is smarter than a Parallax.

A good info source for batteries and charging is at http://www.phrannie.org/phredex.html

I have to agree with Don if you are on grid all the time get one cheap 12 volt battery. You will have to replace it every two years as it will sulfide (see Battery poop sheet).

That Parallax charger is junk and is only suited for folks who run cheap batteries.

Agree with Andy

Having taken Electrical Engineering at Annapolis, I have to agree with Andy about the series and parallel thing...basic Ohms law. I'll go with my cheap Deep Cycle Batteries. Thanks everyone.

the reason i suggested the marine starting batteries, is because they closely match what is under the hood of your truck.

when driving down the road they are charged as a group with your trucks batteries.

Cheap Batteries

I'm going to go for just some cheap deep cycle RV batteries for now. One thing, why would Airstream use junk, in refering to the Parallax charger....I find that hard to believe that they would use an inferior charger like that.

The main reason is that half the people don't care because they run on shore power 95% of the time. The Parallax is a fine converter, it just isn't a very good charger.

The other half (boon-dockers) will throw out whatever is there and replace it with a custom designed system. They don't want to throw out a lot of expensive gear.

What are some examples of converters that also qualify as a good battery charger?

Lots of people here have put in Inteli-power converters. This guy used to offer discounts for forum members. http://www.bestconverter.com/

The balance are using inverters with 3 stage chargers.

Another option is to turn off the converter/charger during the night so that you are not running the system all the time. I just don't trust the Magnetek charger in my unit since I have heard of so many chargers boiling batteries dry. I leave a 1 amp BatteryMinder multi-stage charger/maintainer hooked up to my dual 12 v. Delco Voyager sealed batteries during the winter, after a weekend of boondocking or when it has been overcast for long periods of time. I also have a 5 watt solar panel from PulseTech which maintains the batteries when boondocking for several months during hunting season. The batteries are almost 4 years old and still going strong.

We do still offer the discount to forum members but you have to mention it since we get so many calls from non-members. We also have the batteryMINDer mentioned above in stock.

Batteries

If overcharging is a problem get a battery switch, "Boaters World". With the battery switch you can turn the batteries off and still use your inverter for lighting in RV Park camping, no battery charging.
Switches are made for two batteries. Charge battery #1 or battery #2, Charge both batteries or do not charge either battery.

FWIW, regarding the CBR--

No, you won't need batteries. There are electric and water hookups, though bear in mind, it won't be many amps. It's enough to run things like tvs and lights, but not for things like air conditioners, heaters, microwave, etc.

See you there!
Mary
