2air, last question (at least for 48 hours), I plan to evaluate my chargers per your enlightenment. I assume my solar panel charger is probably ok to stay?

I expect I'll change the other to a smart charger if I'm going to invest in AGMs. I realize I still have lots of measuring and consideration to do. Thanks again for the education.

Convert to two (2) 6V batteries

If you are replacing your batteries, it is a good time to consider purchasing two (2) 6V Lifeline 220 batteries, and wiring in series. This application has proved to work very well in our applications and has been discussed at length in other threads.

This configuration has proven to offer many advantages. You would have to raise the lid of your battery compartment by about an inch, which is easily done using aluminum channel from a hardware store.

well, ah, yeah, maybe....

does it CURRENTLY function ok?

should work exactly the same with new storage tanks (batteries)

IF the sola' was done aftermarket it would be nice to know details...

like brand, model, capacity, features and so on.

the bits a/s uses as oem work, again not top o the line but functional...

http://www.airforums.com/forums/f448...tml#post439986

these are typically sized relative to panel OUTPUT,

so as not to limit collection at peak.

the previously big new thing in controllas was maximum power point tracking...

a feature of 'intelligent' solar charge/controllers,

and now adding temperature compensation makes those mppt gizmos smarter too...

it appears your unit didn't come with agms? so the solar must be an after production upgrade?

3 sets of batteries and looking at a 4th set in just 7 years would drive me wacky...

______

cheers

Yeah, my small and basic solar works like a charm keeping 12v going. I'm not trying to push power to a bunch of gadgets ... just trying to keep the lights on and the heater working at night. It's aftermarket and I don't have the specs or my Airstream with me right now. The A/S was prewired then I had the Airstream dealership in Alachua, FL put one panel and a controller on.

I didn't know all this intelligent power and temperature stuff existed. I think my plan is to thoroughly map out my options before making the change to AGMs. I want to be sure I do it all the right way ... and now you have me tempted to reconsider my solar situation. Frankly, all this learning and tinkering is much of the fun for me.

BTW, I had a forum username UAPachyderm back in 2008. I didn't post but a few times and then quit visiting the site. Recently they came out with an App for the iPhone so I started reading through the forum again. Initially I forgot that I had once signed up ... then I remembered but couldn't remember my password. Long story short, I'm going to ditch the 28CCD username/account and go back to the UAPachyderm username/account.

2air, thanks again for all the info. This is my username going forward. I'll be on here much more often now that I can read and post from my iPhone.

I purchased from Sears because it was just easier (locations everywhere) even if more expensive (didnít price shop). I considered Sears largest Platinum Marine battery but its form factor was almost an interference fit in the battery compartment; was do-able but would have been a bitch to R&R and was about $50 each more expensive.
For those of you who might need additional incentive for the DieHard Platinum Marine battery, see: Sears: Online department store featuring appliances, tools, fitness equipment and more

If you scroll down the page you will see:

This product is:
Available for Gift Wrap

That ought to help break any ties.

Imagine:

Lift the 53 pound rectangular package, "Unhhh!"

Shake, shake, shake...

"What could it be?"


I will admit I'm considering a couple of these. Not sure if I'll opt for the gift wrap, though.
