Duel 6V Battery Venting

OMG Point of order (LOL)

There is no "by far" unless you are comparing GC-2's with group 27 hybrid marine batteries. The disclaimer of "if one of them goes out" doesn't really seem to happen and if you have 4 or more, then it's a mute point.

Here's the math

Using the min@25A rating;
2 6V T-105's; 447 min / 122 lbs = 3.66 min/lb
1 12V T-1275: 280 mi / 82 lbs = 3.41 min/lb

Using the 20 hour Ah rating
2 6V T-105's; 225 Ah / 122 lbs - 1.84 Ah/lb
1 12V T-105; 150 Ah / 82 lbs = 1.82 Ah/lb

I will agree that if you are only using 2 batteries, it's more of a personal choice between 225 Ah @ 124 lbs or 300 Ah @ 164 lbs. If you are using 4 or more, the advantages of 6V become more prevalent. If you go to the Lifeline website and look at their min@8A rate, there is even more separation between the advantage of 6V over 12V. Trojan does not give this rating in their chart.

The only advantages of 6V are size and weight. You have less to lift at one time when moving them. They come in larger sizes. That's it.

What pvc fittings did you use to vent out of box to hose?

I cut out a square around the flange from the old box. Drilled a hole in the new box and screwed it to the new box from the inside, along with some silicon sealant.

Oregon Camper, what pvc fittings and size did you use to go to the vent hose from the box. Thanks Don

Sorry if I mislead you...that is not my setup. But, perhaps it will be in the future.
