Yes, the golf cart batteries have significantly higher capacity at high discharge rates, but comparing two 6 volt golf cart batteries to one Group 24 12 volt battery is an exaggerated comparison. In the first place, the two 66 pound golf cart batteries are better compared to two 65 pound Group 27 batteries than to one 56 pound Group 24.

In the second place, you can't compare the golf cart batteries' published 492 minutes at 25 amp discharge to the 25 amp ratings of 149 minutes (Group 24) or 186 minutes (Group 27) where the total discharge for a pair is then is 50 amps, double that you use for 492 minutes for the golf cart batteries.

At 25 amps total discharge, 12.5 amps each, the minutes of discharge are significantly greater than those published by Lifeline for a 15 amp discharge, 259 (Group 24) and 324 (Group 27). You get no argument here the golf cart batteries have significantly higher capacity, but nowhere near the difference in the exaggerated comparison.

At lighter discharges, 11 amps for the pair of golf cart's, 8 amps (Group 24) and 10 amps (Group 27) for a pair of 12 volts, the capacity difference is much smaller. A pair of golf cart batteries have a 10% advantage over a pair of Group 27s, but a 37.5% advantage over a pair of Group 24s.

Where you can deal with their height, the golf cart batteries have the advantage of smaller footprint. Where you can't, as in the Group 27 compartments of our trailer, the 12 volts are still the reasonable choice.

One more question

Thanks everbody for the info, Royce, RoadKingMoe, Lewster, TomW, Gunnyusmc and doorgunner, all good information. And altamont, I hope I answered your question.

I am leaning toward the Intellipower and 2 Group 27 Lifeline AGM batteries. Since RoadkingMoe put Lifeline 27 batteries in his classic box, does anybody know if I can fit the Group 27 in my battery box located on the tongue of our 2006 Safari 25FB?? Has anyone else done it??

Thanks,
John

John, for what it's worth, we tried to fit 2 group 27's in the compartment of babebloos CCD Bambi, and even though they would fit with the compartment on a bench, having the compartment on the tongue puts obstacles in the way. You definitely could not use the hold down in the center of the battery compartment. The plastic battery tray will have to be removed, of course. It's a matter of there not being enough room to angle the batteries down into the compartment.
That said, if your compartment is wider, and if there is more space between the front skin and tongue jack, then that might work fine.
As far as the Intellipower 60A charger with the charge wizard are concerned, it is far from perfect. It is a noticeable improvement over a vintage Univolt, but it is definitely not as quiet and electrically savvy as it's hype would suggest.
How do I know? I have a 60A unit with charge wizard in my 63 Overlander. The fan does kick on, and it is NOT quiet. If you run vents at night, the fan will kick on several times, and does make a fair amount of noise. It also boiled dry 2 group 27 batteries in 2 months time, I did not notice until it was too late, now the batteries are junk.
When the fans are not running, the Intellipower is dead quiet. It provides very stable 12V power to my trailer, even with all the lights on and the fans etc. I am very pleased with it's small size, great performance as a converter, and it's reliability.
The noise level, charger circuit and the Charge wizard thingie are overrated, though. This is one consumer's experience with teh Intellipower 60A converter/charger with the charge wizard attachment, purchased from bestconverters.com

John, two comments. I support the change to a multi-stage charger if you regularly use the converter to charge the batteries, espeically of you switch to either Gel's or AGM's. The Parralax is a constant voltage charger which will try to maintain the battery voltage at 13.8. This will lead to overcharging AGM's or Gel batteries and unlike wet cells you can't add distilled water periodically to keep the cells from drying our and warping.

We have not switched out our Parallax system because I rarely use the converter to charge the batteries. I typically switch the batteries out of the circuit when connected to shore power to avoid over charging. I use our 260 watt solar panels and the solar charge controller that is temperature compensated to reduce float charge voltage as temperatures increase.

There is another option. You can purchase a new Magnetek three stage charging section from Best Converters with breakers and fuses to install in the Parralax converter. It might be cheaper and would solve the overcharging problem but it might retain the original Parralax cooling fan with is the source of the noise you notice when the unit switches it on.

As others have said, talk with Best Converter for a recomendation.

4455TC ParaMode

Install complete of the 4455TC ParaMode converter. Thanks to Randy of Best Converter for the assistance.

Intial thoughts: Install was easy, took about two hours. No instrunctions included with the converter but Randy's assistance cleared up all of the questions. Unit is absoultly silent expect for the fan. Fan ran for about 3.5 hours during intial charge cycle. The fan is a little louder than the fan on my desk top computer and only runs when needed. Much quieter than the old Univolt. I had to rerange the fuse block and the water pump to have room for the ParaMode. Had I chosen the WFCO it looks like it would have gone in the same spot as the Univolt. I am counting on the temperature control to be worth the extra effort and cost. Wish I had changed out the old fuse block while replacing the converter. Job should have taken about an hour with instrunctions and I had to work under the dinette. My only complaint is the lack of printed instrunctions for install.

Thanks again to Randy of Best Converters for the assistance and the prompt shipment. Great service!

Maybe I should make a new post, but I thought I might hijack this older thread and see what happens...

I have a 2007 Bambi CCD 16ft. There is a Parrallax 7355 under the bed and under the dinnette there is something marked as WFCO and it looks like some kind of converter/charger, too.

A couple of weeks ago, somehow the 110v over the kitchen counter got shorted out. I could see that the wire coming through the aluminum inner wall had rubbed and cut where the grommet was not seated properly.

I fixed the wire and the grommet. Now, the lights dim when the heater kicks on, the battery has charging problems, etc. I ordered a 7355 R/U lower replacement unit for the Parrallax under the bed. I am hoping this will do the job.

If anyone wants to give a quick schooling on what the 2 different (the parrallax and the WFCO) units "do" - it would be much appreciated.

Thanks.

If you are able to snap a couple of photos and post them here it may be helpful.

This should have all been covered under warrenty. Send your bills to the factory and get re-imbursed.

Yeah I am going to do that. I have documented the wiring. In the meantime I am in the middle of nowhere. I am having a 7355 lower unit shipped in.
