Good question. Thanks. The batteries are wired correctly - I took pictures before and after and they match up. I checked the volt meter on the car battery and it read 12.89 so I assume its reading correctly. Camping World says not to mix AGM and Wet cell batteries in part because the controller is set to one or the other - and it now has both. They recommend that I replace all the batteries with AGM.

Things have taken a turn for the worse. After consulting with Oliver I bought a new battery from Camping world - same power output etc - but an AGM - I was told by Camping World that it was ok to substitute an AGM for a wet cell. The power came on but this morning all 4 batteries are dead - and all now read the exact same voltage (241.0 V. I put a ticket in with Oliver and am consulting with a Camping World nearby.

Now that is in my ballpark. My controller with the lithium option should work. I don't know how important this is from Galway Girl as I would not be using Lithionics In my specific hull 505 I have a Progressive Dynamics 4000 load center. This houses the AC Breakers, DC Fuses and a converter section for battery charging. In my PD4000 there is a PD 4065 Converter section (65A) with Lithium Jumper for Battery Charging. In normal operation that charger is set to WIZ (or Lead Acid) position and it follows a profile that's perfect for lead acid batteries and AGM's. If I move the switch (or jumper) to the LI position, it now has a constant output at 14.6V which is OK for Lithium but not optimum for the Lithionics batteries. Lithionics prefers that I use another charger with a programmable LI profile. My Plan: I'm upgrading my current PD converter charger and separate Prosine 2000W inverter to an integrate Xantrex XC2000 Pro Charger/Inverter. Note: I don't plan on running my AC off the batteries so the 2000W inverter is plenty for my needs. In the Platinum Package Oliver installs the XC3000.

Great thread! Thanks! John also sent me some great stuff - lots to chew over.

Yes- we needed power now - so I went to Camping World and bought one battery - and everything is online but we will either upgrade to lithium or replace the other batteries shortly. I always planned to upgrade to lithium - I have lithium in the van and it works great. I asked Oliver the cost to upgrade to lithium - I just wanted to see what they would say - and they quoted $11,000 for 3 130 AH batteries (!) so it must be much more than a plug-and-play type thing. I'm not sure about lithium now and am trying to figure out what's required.

I added the image....The batteries - which say they are deep cycle marine batteries - appear to be in parallel but there are these extra cables that I don't understand. With the power gone the heat is not working - darn...

Thanks Chris, We have 4 wet-cell batteries. I'm not sure about the wiring - it looks kind of convoluted to me. I'll take a picture. We do want to go to lithium at some point. We have the Zampp controller which does have a lithium setting but are not sure about any other changes that are needed.

Thanks - Even if it's better to replace them all I'm thinking I'll probably just replace the one and then replace them all at some point - they are four years old - and I read the lifespan is 3-5 years - and then maybe switch to lithium.

I have one dead wet cell battery and 3 fine ones. 2019 trailer - original battery set. Can I just put a new one in there or do they have to be of similar age?

Thanks GJ _ I was totally surprised to se the XAMP panel, I think it is, has a lithium option 🙂

Nice idea, John. Those power stations are impressive and getting better and better.

Definitely interested Max! Will PM you 🙂

Thanks again for all the help! The interior - such as it is at present 🙂

Thanks so much! We have the Trojan lead batteries which seem to be well-maintained and will probably keep them for a while but do plan to move to lithium. I have Battleborn lithium in the van - and they work so well :).

I have the 4 Trojan batteries which we would probably replace with lithium at some point. I haven't yet determined how costly that will be. I do see that the solar setup will accept lithium - so hopefully it's just a matter of putting the lithium in. I imagine it will not be easy to add an inverter in - I will check it out though. I have plenty of power from the solar array on the van, and since the weather is still good, I'm hardly using the Oliver at all; its more for bad weather and for my partner when she visits - but it would be nice then to get the outlets working.

The only reason I can see to get one is to use the outlets without using a generator. I'm almost almost always boondocking.

Well, I have the answer - the former owner told me there is no inverter....I guess that's the way it came. It's weird because trailer seems to have just about everything else - double awnings, Truma water heater, solar, double propane tanks, WIFI, CD player, and I don't know what else - but no inverter. The previous owner said the outlets would only work with shore power or when using a generator. I wonder how hard it would be to put one in?

Thanks for all your help! This is a single bed setup. I have looked near the floor, in all the under compartments, all the upper storage areas, in the closet, The bathroom (yes, I'm getting desperate), in every outside opening and I don't see either the inverter or the prowatt panel anywhere. The manual says it came with them. I don't know how but I must be missing something. I'm trying to get in contact with the former owner and see if he remembers.

I see it in the manual but have not been able to locate it in the trailer (lol)

Thanks Mobile! I actually looked in the manual and that's what I have. Where in the trailer did you find that?

Thanks for the advice - these are not new batteries.

Thanks - that's a nice panel - unfortunately I either don't have it or can't find it. The CD player is below the solar panel. Is it possible that there is no inverter? I don't see it anywhere

That makes sense there's no button there! I'll look around 🙂. I don't see anything in the cabin.

Thanks. it has two buttons that I can see - the amp/volt and battery type - I don't see where to turn it on. The battery voltage says 13V. I don't know about that red light - charging status?

Thanks very much for that. Who knew?
