Curahee posted:Curious, how do you all get a high enough equalize charge (the 30XHS requires 16.2V for EQ)?
I would love to go with 2 of those if they fit or 2 T105's but the Lance PD-4500 won't provide the proper EQ charge...
Cris and Krista, the question about equalozing is a good one. I am not an expert, but I do think Imhave a good answer.
Of course, the Lance supplied charge controller does not provide an equalizing charge comparible with this Trajan battery. And batteries are all,different in terms or bulk, float and equalize charge requirements. So no matter what battery you have, it most likely is not truly compatible with the charge controller.
The equalize charge is a special case on 12 flooded cell and agm batteries because is is so high. Lance connects the charge conroller to the battery and all the traoler 12 volt systems. We dont want the correct battery equalize charge applied by the charge controller, because, using this example, 16.2 volts is likely to damage some 12 volt loads, maybe the fridge, etc.
In my case, my plan is to use a programmable solar controller in conjunction with a 100 watt portable solar panel to both charge and equalize, equalizing only when disconnected from the domestic (trailer) system. In fact, when plugged into 120vac, I possibly will always keep the battery disconnected, so, the battery only sees the correct bulk,float, and charge parameters.
I am waiting for my trailer delivery, so this is my plan...
We use the factory solar controller and/or the factory PD-4050 controller for normal charging, and a Vector 1089A digital battery charger for equalization. Peak voltage in that mode is 16.2, temperature compensated.

Attwood powerguard 27 box inside dimensions:
13 7/8 x 7 1/4 x 10 1/2 =
13.875 x 7.25 x 10 .5
Trojan 30XHS dimensions:
13.94 x 6.75 x 10.09
According to specs it doent fit lengthwise! Does it indeed slide in and out without a problem?

Brian, when you equalize, do you disconnect the battery and Vector charger from the trailer electrical system to prevent the loads and charge controller from seeing 16.2 volts?
Yes. Sorry for the long delay - Happy Holidays, btw - but I equalize with the battery isolated. No solar, no trailer loads.
I had to change the stock battery disconnect to achieve that.
Hey Red..
How is the 30XHS working out.. I have a 1985 and like the weight savings over (2) 6 volt batteries.. I occasionally do an overnighter at Cracker Barrell but usually am hooked up at a State Park, etc.
Thanks, Joe

Love it! 
We recently dry camped for 3 nights and I didn't bother bringing the portable solar or generator. No problem. I bet we could have gone another 2 nights.
We have another 2-night trip coming up and the solar & generator will once again stay home.
You will not be disappointed if you purchase one.
Thanks.. looks like I'll get the same box you got too..
Joe
You'll be happy with the Attwood (not to be confused with Atwood who makes our stoves, etc...) group 27 box as well.
It holds group 27, 29, & 30 batteries as well as goes perfectly with the B&D lock.

Why did you need to change the stock battery disconnect switch to isolate the battery? Doesnt the stock disconnect switch (in my case on a 1575) isolate the battery?

Good question and I'm curious to hear the answer too.
Jeff..
I'm stealing your ideas for 30XHS and box.. Did you do anything with the vent holes on top of the box?.. Also, did you install any drain holes in the bottom?
Thanks Again, Joe
^^^ Joe, I too stole the suggestion of that Trojan battery for my 1475. The NOCO HM318BKS box I chose (same as BrianV as confirmed with him) fills up that box completely while not having porous vent holes on top to collect water.

You won't be sorry that you got this battery.
I do have holes in the bottom of my box, but don't have time to post pictures. Also, I store my battery & box in the garage between trips so there's another reason why holes on the top aren't much of an issue for me.
If I were you I would get the box that DD J has (& posted above) as it doesn't have holes in the lid & looks like it works with the B&D lock. Nice find DD J!
Hi Red, I've been reading through your thread re: the Trojan 30XHS battery set-up on your 1575. Thank you so much for such a thorough write-up, and I'm certain this is the route I will go with my 1575. I have one question which is probably pretty dumb; in the picture showing your Victron shunt attached to the battery - is it permanently installed there? Not being familiar with the battery box and actual size of the shunt, just can't tell if there is enough space once you put the lid on the battery box on.
Also, I've read other threads where people run wires/cabling for the monitor from outside, to inside the trailer and mount the monitor inside. Did you do this? Or, do you just periodically run checks from a connection outside the trailer? If the former, would you mind sharing with me where you ran the connections for a 1575 specific installation?
I'd also be grateful for any updates or lessons learned you might have in the last year+ since you started using the Trojan.
Thanks a bunch.
Hi Laura,
Sorry I missed this. Been busy with fires in our area. Evacuated with the trailer one night - dry camped in my sister-in-law's driveway & the battery was still at 96% in the morning with a lot of furnace & water pump use. Been on high alert ever since ready to roll. Driving back home brought the battery back to 100% & it is now plugged in to the house remaining fully charged.
Just taking a rare rest this week and got on LOA. This will be short, but ask away for expanded answers & I'll reply deeper in a day or 2.
The battery is fantastic and packed with AH's!
It fits in a group 27 battery box.
I store our trailer without the battery & LP tank. I store those in the garage between trips.
I have a Victron battery monitor. You can find a link to it in my signature thread.
The shunt I install before a trip along with the battery. It fits in the battery box with no issues. The battery box lock keeps it all safe.
My Victron display I chose to mount inside the under-the-bed front storage area. I am out there a lot while camping and I didn't want another display inside the living area of the trailer. Again, Victron thread is in my signature thread.
If you want the same battery box & lock that I have check out the battery lock thread in my signature.
Here are 2 pictures that I just took. Battery & shunt in the box locked up. All we have to do is unplug the trailer & we can be rolling.
*Even though I wiped it off before the picture there is still ash on the box.

Jim, thanks for your reply. I'm sorry to hear about your evacuation situation, but it sounds like things are working out ok for you. My brother was on evacuation Alert for the McCourtney fire and Lobo Fire near Grass Valley, but those passed him by. Two years ago a fire came to about a 1/2 from his house. The West is a mess this year. 
You're installation of the Victron was just what I was looking for. Your 1575 tips are fantastic for the rest of us 1575 owners. 
What do you do to totally isolate the battery w/o disconnecting the cables? I ask because the switch at the front just disconnects the one side I believe.
Thanks in Advacne,
Louisb
