Re: Montana high country 338DB needs more batteries
GoPackGo wrote: You could do that. I looked at the MTS web site. They make the individual vent components, so you could add another outside vent (one for each 6-volt battery). But they do not apparently make the part that the vent hose would attach to on top of the battery. Perhaps you could make up something out of PVC from Home Depot. And if you could figure a way to join 2 vent hoses into a Y configuration, you could use your existing single vent on the outside of your fiver, otherwise you'd need to add another vent outlet. I believe NOCO makes a box that will hold both 6V batteries in one box. Then I would just use my existing vent and drill a hole in the top and do like you say with some PVC or something to attach it. I think this might be the route I go.588Views0likes0CommentsRe: Montana high country 338DB needs more batteries
GoPackGo wrote: I used the NOCO HM306BK models ON MY BOAT. They have small vents on the top. Cables are routed through any of those squarish protrusions you see built in to the corners of the caps. These also act as vents. So there is lots of venting - just not directly to the outside. They are good, heavy duty boxes. My fiver came with boxes that look like the ones in your last link (has vent hoses attached). I am not qualified to give anything more then an opinion. I don't know the volume of gases given off so I don't know how crucial it is to have direct outside venting. I do know that you want some kind of venting. My fiver has the battery boxes in the front compartment with vent hoses leading to vents that face outward on the front. The batteries give off nasty fumes when being recharged so you do want some kind of vent arrangement. The compartment on my rig also can double as the genny compartment and because of that has cutouts in the bottom that allow air circulation as well as for an exhaust hose exit. Because of this, I would not worry if the boxes were not directly vented. IMHO, you do not want boxes that have open drains in the bottom. Any liquid going out that drain will be acidic. I don't want something like that exiting out the bottom and being spread all over the bottom of my trailer. I want boxes with sealed bottoms. I kind of agree with you, if I had a leak I wouldn't want that spraying all over the underside of my fifth wheel, that would make a mess. I think maybe I should order one of those boxes and maybe, but maybe not cut in the outside vent in to the lid of it?588Views0likes0CommentsRe: Montana high country 338DB needs more batteries

I like the vent though. Can you daisy chain those together if you have more than one? I don't know about using one vent for multiple batteries.588Views0likes0CommentsRe: Montana high country 338DB needs more batteries

I put 2 6V batteries in last night. Only thing I need to change is the battery box. The battery is too tall for the existing box and I used a marine box for the other one because that's all I had. RV dealer wanted $149 for one and that is crazy. I've been traveling and just got home and need this to leave tomorrow, so for now it's ok, but I'd like a good box that holds the 2 6V better. Does anyone have a good source for those?588Views0likes0CommentsRe: Montana high country 338DB needs more batteries
Lyle, Thanks for that. For the price difference, I think I'm going to buy the 6V batteries at Costco. For $83.99 I don't think I can go wrong. They are Interstate GC2. They are not the HD GC2, but still plenty for what I'm doing and $100 cheaper then buying 2 Trojan T-105.226Views0likes0CommentsRe: Montana high country 338DB needs more batteries
So, given the same exact draw, how much longer will a pair of T-105 last compared to one Trojan 31-AGM? I'm asking this because it would be about the same cost for batteries. The capacity of one T-105 is rated at @25 Amps 447 minutes The 31-aGM is @25 Amps 177 minutes Does this really mean I'll get 270 more minutes out of them?226Views0likes0CommentsRe: Montana high country 338DB needs more batteries

I did, and I get about 1-2 more days' camping than my dual 12v's gave me, depending on use. Yeah, maintenance is higher, but it's not a huge deal. Buy a watering system to make keeping them full is also a good investment. Now, if you plan on dry camping more than you currently do, the larger investment might be justified. Lyle Don't know where in the world you got a quote for T-105s that high. I paid $76 each for the four I've got two years ago. Considering they are the gold standard for flooded golf cart batteries, it was well worth it. About the AGM vs. flooded thing. I've got 400w of solar charging the batteries and do have to check the water level once a month. It sometimes is down 1/4" or so, but never has been more than that. If you don't want to do that and have the extra money, AGMs are fine. A reminder in your Google Calendar is a lot cheaper IMHO. You got T-105 for $76? I was quoted $135226Views0likes0Comments
