New Battery Location

I am doing some modifications to my 1961 Tradewind. Since it did not have a converter, and the batteries are really no longer available, decided to install a converter. I am using the original entry for shore power and running it through a chase I am installing just in front of the black water tank. I am extending the "throne" platform about 2 1/2 inches to cover the chase. I am installing the converter in the bottom of the rear closet. That way I have an easy run for new 110v circuits to accommodate a microwave and the A/C unit and some additional 12v circuits. I am considering putting a new battery in the rear storage compartment in a battery box. Any problems with putting the battery in that rear compartment basically next to the tub and under the bathroom sink to be accessed through the outer hatch in the rear behind the spare?

Many older Airstreams had the battery in a back compartment as they came from the factory.

There are two things to consider:

1. The weight of the battery in the back. Don't overdo it, as many Airstream frames are not really good with a lot of additional rear weight, such as bicycles and so on. If you have a 4" frame on your 24' it may be marginal as to additional rear weight capacity.

2. The 12 volt charge capacity while towing will be reduced because of the long run of the wire from the TV engine to the rear mounted battery. You probably should expect only 3 or 4 amps in that situation.

You also mentioned a rear mounted spare tire. That puts additional load on your frame already.

Battery type and location options

Thought I would also post this here since it's related:

If considering multiple batteries, please check out the Optima units. Their "yellowtop" units have great deep discharge capacity and have more amps in smaller sizes.

Depending on your battery box, you might be able to fit two smaller batteries that each have equal or better ampacity than your single old style.

Because these are totally sealed there are typically no out gassing problems unless charged too aggressively.

Many car applications have them mounted on their sides in remote locations. They must be isolated and charged separately if used in a parallel application.
