Lew,

Just thinking, since I've gone this far, seems I have laid the foundation with the batteries and charger upgrade to add a Solar Panel?

What else would be required to complete the task of adding Solar?

Jack

Jack

A panel or two and a quality solar charge controller that has A programmable, ADJUSTABLE charging output.

Lifelines are most happy with a bulk/absorb charge of 14.2-14.4VDC and float charge of 13.2-13.4VDC, both at 77 deg. F.

Temperature compensation on the charge voltage Is also highly desirable.

Received the batteries and installed yesterday.

Note: Must remove the bottom plastic tray AND the center threaded rod in order to get the batteries in. The fit was VERY tight. Finally got them in but I sure hope they last as there is no way of getting them out short of cutting the battery box back lip off.

Put in the charger this weekend and will advise results at that time.

Put the charger in about a week ago. Everything is working great.
As I like to dry camp on occasions and anticipating a substantial improvement in battery life.

I have what I hope I can get a simple answer to a battery question. I have a 30ft, 2014 Flying Cloud, 50amp. When I come home from camping I would like to keep my two batteries charged. I keep a battery minder hooked to the batteries. In order to charge the batteries, I was told via email from Airstream, to set the "storage/in-use" switch to "in-use" in order for the minder to charge my two batteries. TRUE OR FALSE? If false, tell me what I should do to keep the batteries charged. I know I'll have to watch the water levels in the batteries. Thank you for your kind help!

If the battery minder is connected directly to the batteries and power, the use/store switch is best left in store position to avoid other things draining the batteries.

I am hoping to make the switch to a pair of GPL 27 T. With my 2015 27 FB, I have the access door in the way. To go 6 volt I'd need to to more mods than I care to do. Also, for my type of camping, I would be ok with 100 amp hours per day as long as I bring my eu 2000i. HOWEVER, as I look at the picture of the GPL27, I see just 2 battery posts per battery. My setup looks like this...
Any help is appreciated.

When properly connected, you only need one positive and one negative post per battery.

There are several photos of a pair of AGM group 27 batteries wired in parallel that you should easily find in a search of battery threads.

All positive loads connect to the positive post of battery one and all of the negative leads connect to the negative post of battery two.

The parallel cables (which should definitely be larger than your 6AWG pieces of pasta) should run positive to positive and negative to negative.

Thanks Lew, for all you Dew !



You know, I've kind of lost count of the number of times Lew Farber has unselfishly stepped up to the plate to answer our questions. We are very lucky to have him around !

I thought I'd take a minute say "Thanks" and also.....

Remind folks that the batteries and converter mentioned in this thread and others are also available from Lew !!

I know we all love good deal and I'll bet Lew will deliver on that good deal AND a Good Deal More !

Merry Christmas to all and All the best through the New Year !

I had to do the same and have the same fears about replacement but will cross that bridge when I get there. Hind sight says I should have gone with the taller 6v cart batteries, raised the lid and picked up the extra amps. Lazy me....

I did however place a rubber mat to put the batteries on and drilled it to match the existing holes in the bottom of the box. Initially i was concerned about no tie down after cutting the rod, but the fit is so tight I don't think it will be a problem, though I did place a couple wedges between them.

as I ponder the wisdom shared, I see that, even if I made no change, the stock batteries are not connected properly from the factory. Lew, unless I am hallucinating, the negative car type clamp should be on battery two....
Then it is also true that the "less than stellar" performance of the stock batteries could be the result of this odd installation.

You're starting too 'get it'.
