Ok, i've done my research, measured my area for a 2-battery bank and am looking at these two possibilities:1) Lifeline - GPL-6CT RV - 2 6-volt AGM batteries - $440.99 + s/h - Total = $1,023.942) Trojan - T105-AGM - 2 6-volt AGM - $275 + 27 core - Total = $640Looks to me like the lifeline would provide a much greater (almost 40% more) battery capacity; while the Trojans are about that much cheaper. Am i thinking right?? What say you?

Up here Trojan T105 are running around $165 each, so is there really a AGM version thats $100 more each? I cant imagine having $1000 worth of batteries sitting on the front of my rig (or walking away). If your a dedicated dry camper 2 T105 + small inverter + Honda/Yamaha generator (or solar) will serve you well.Daryll

In late 2013 I paid $440 for (4) Trojan T-105's..........I fail to see any value in an AGM battery at $300 per battery.......what are you specifically trying to accomplish with the AGM 6 volts?

Is 6CT Lifeline an L-16 size equivalent? That is a big battery, make sure it fits.Either should prove excellent. If price is a concern compare $$ / Ah

smkettner wrote: If price is a concern compare $$ / AhAnother reasonable comparison is $$/Ah over the projected life of the battery. Also, of consideration is whether it is a maintenance-free design or whether you have to add water to them. How easy is this to do on your coach and how willing are you to do it?Particularly, with the wet cell, your "care and feeding"/keeping water level at proper level is a large part of the equation.

These is a brand new Trojan series, "Reliant" which is AGM, thus no upkeep. Thanks for the insight in price. The Lifeline is also AGM, and is similar in size to the T-105's. I had checked the L-16, but these are too big for my rig space. What I am trying to do is get a good 2-3 night weekend out of the batteries, and not have to get a generator to start. In the future I'll get a generator to go longer, but now I figure if I can make it for a good long weekend, and just hookup at end and drive home and have the TV charge them back up on the way home that should be good! Just trying to get the best bang for my buck, but not break the bank, of course. I seem to be too far from any dealers around here, and will need something shipped to my home, or possibly to a dealer near harrisburg, pa or lancaster, pa.

When the 8955 Whiffy was floating at 13.7 I fitted an inline 500-ampere Schottky rectifier to drop voltage three tenths. When the Whiffy smoked and upon autopsy I damaged several ribs laughing, I now use the BORG. But it is going to be replaced by the GigaWatt.

The 10-amp Whiffy fuse failed. I replaced it. Plugged it in. One of the two bi-polar transistors popped off a chunk the side of two dimes, stacked. The shrapnel pinged off my safety goggles. When I unfastened the heat sink from the corpse I found Whiffy did not use a micro-gram of heat sink compound on the cheap grade Chinese heatsink "counterfeit Berquist Sil Pad" pad. Wiffco may be manufactured in northwest Pakistan or the Hindukush as far as engineering land mines are concerned.

I am going to have to switch voltage regulators on my toad when I fit an AGM. The factory ECU voltage regulator is crazy-nuts too high of voltage for an AGM battery that will be subjected to 150+F under-hood temperatures. I am going to do with a remote rheostat (already made up) Transpo 911-02 voltage regulator.

But again, this is for "far-side-of-the-moon" environment. Celsi is going to construct a 13" tray underhood, and the battery is going to be wrapped in 316 grade marine stainless cable so it doesn't spring out of jail and run down the road. It is amazing how well a 12-volt electric fence charger works when isolated atop rubber tires with a stainless braid ground strap connected to the fence charger opposite post. A key FOB 12-volt remote switches the system.
