Epoch Lithium Battery Storage Info- I reached out to Epoch Battery Lithium battery customer service (Stockbridge, Georgia) regarding our recent install of (2) of Epoch 300ah (self heating) batteries in our OLE2 and correct SOC during short term winter storage. They responded quickly and this is the guidance they provided. This information is for anyone that now owns or is considering a swap at some point from aging AGMs over to Epoch 300ah batteries. Epoch recommends 1-6 months in storage a 50-70% SOC. Epoch does not recommend leaving the batteries plugged in 24x7 via 30amp power and maintaining the batteries at 100% SOC during storage months. Just passing it forward!

They use a really strong industrial strength glue which I do not recall the name of. I do know that they use this adhesive in ALL their RV and Marine fiberglass installs. The next time I speak to the good folks at Inverter Services, I will try and remember to ask him about the adhesive they use. 👍🏻

Here are my thoughts: edited- We previously owned an Overland Trailer (which had a Max Air fan). We experienced a voltage issue so I had the Orion-Tr 12/12-9 installed to stabilize and maintain 12v power to the fan. Now I do not have to be concerned about possible spikes or a malfunctioning control board. Max Air Fans operating above 13.8v can damage the fans control board. This will prevent damage to the sensitive control board. The black plastic board material used to secure all components is called Starboard or Black HDPE and I can tell you it’s super tough and used in Marine grade applications. Inverter Services uses lots of this material during their installs. Here - https://www.amazon.com/gp/aw/d/B08M6DJNH4/?_ Open Source info on Max Air Fans- *** MaxxAir fans are designed for a 12 Volt DC system, operating within a voltage range of approximately 10.6–13.6V, with an optimal test voltage of 12.8V. Operating above 13.8V can damage the fan's control board and void the warranty, especially if the system is charging. To prevent issues from voltage spikes, a DC/DC voltage regulator is recommended for stable power, especially when the vehicle's charging system is active.

It sounds like a fun trip! 😊 We have had limited experience camping in below freezing temperatures, and not in the mid teens as you mentioned. Our temps were in the mid to upper 20 degree range and only for a short couple of hours before sunrise. Our Oliver was not winterized and we had no issues with frozen water lines. We always make it a point to not to connect to city water with a freeze warning and use our on board water. We don’t drink from our fresh water tank, and always carry plenty of gallon jugs for drinking water. Our typical sleeping temp is 61d and we run a dehumidifier which keeps our interior just about perfect at 55% humidity. We always leave the bathroom door open to keep warm air circulating. As @topgun2 mentions there are lots of variables to consider. I think you will be fine just stay weather aware for sure. Safe travels and let us know how your trip goes!

SOLD on 11/21/25 on FB Market Place. Looking to find a new home for my gently used Xantrex Freedom XC 2000 I/C. If there are any takers that may have sorta of a use for it, send me a PM to discuss price. Shipping is on your dime if interested. The Zamp solar charge controller goes with it.

Steve, glad to pass it forward. If you go with Inverter Services, I think you will be happy with their work. Jim Posey whom I think you have seen on the Oliver FB page referred me to this company. He has had a lot of work done by them on different RVs over the years and believes they are one of the best. I agree.

John, Under the rear street side bed right where the former Xantrex 2000 was installed by Oliver. A custom platform was added to secure the longer a heavier Victron Inverter/charger.

Thanks Bill, We will set a time up for you to come by for sure! 👍🏻

Thanks! Plan on 1-2 weeks depending on what you’re having done. They had the SoftStartRV in stock for our Truma. They typically have a 6-7 month wait time for an appointment, they are that good and 💯worth the wait based on our experience. I happened to a call and ask if they had a cancelation, they did. I was originally scheduled for March.

Thanks Mike, We were due for the upgrade and this system gives us many more options. Cannot say enough about Inverter Services. Cumberland Mountain SP is well kept, with level sites and it was super quiet which we like with only a handful of late fall campers. David

***Long Post*** XPLOR Hull #634 Victron 3000 watt inverter, Victron 12v DC to DC charger and Epoch lithium battery upgrade. Note: To discuss options and pricing, please contact Jordan Hall at Inverter Services, White House, Tenn. Our OEM AGM batteries were getting long in the tooth and it was time to upgrade our batteries to a complete lithium battery system on our 2020 Oliver LE2. Our good friend, and former Oliver owner Jim Posey, highly recommended we speak with Inverter Services in White House, Tennessee. I called and spoke with Service Manager Jordan Hall and discussed our needs and options. Jordan and his team at Inverter Services were excellent to work with and have a lot of experience working on Oliver travel trailers. Our tech/installer, Easton Ford, kept us updated on our install progress with photos and discussions as needed. We found Easton to be extremely detail-oriented and dialed in and focused on our project. We were originally scheduled to have this work done next March. After returning from our 54 day New England and Canada trip, I decided to call Inverter Services and ask if they had any cancellations. They did and we immediately took the cancellation. They are typically booked 6-7 months out. So we hitched op Oliver and headed to White House, Tenn to leave our Oliver with the team for 2 weeks. Important note: Inverter Services supports the RV and Marine industry in ALL things lithium battery and electronics. This is one of the most detailed and thorough, cutting-edge companies we have ever done business with. I chose Inverter Services to do this install because this is not my area of expertise and it absolutely is theirs. These guys are experts in their field and I admittedly am still in the learning process. Based on our excellent experience, we highly recommend Inverter Services in White House, Tenn if you are considering a lithium upgrade. We chose all Epoch & Victron following products for this install. (2) Epoch 300ah lithium batteries (internal heating elements) -https://www.epochbatteries.com/.../12v-300ah-heated... *Victron MultiPlus-II 3000w Inverter/charger *Victron GX 70 Touch Screen *Victron Smart Solar MPPT *Victron Orion XS DC-DC Battery Charger **We also had the RV Soft Start installed on our Truma Aventa AC. Inverter Services provides tech guidance/support/firmware updates as long as we own our Oliver. I cannot stress enough the pride this company takes in their work. As I think most would agree, Victron components are a class all their own and leaders in the Marine and RV industry. Post install, we have on board 600ah of lithium battery power, and with our extra 90W Zamp panel now configured to lithium, we have approx 410 watts of solar. This will certainly give us more options on the roads less traveled and boondocking. Still lots to learn on this new system. Now having the 12v DC -DC charger I don’t think we will see a need to carry a generator any longer. Thanks to all those on the forum who made the Lithium upgrade happen. ⚡️ The information gleaned here helped me decide the direction I wanted to take this install. ⚡️Happy Camping and Safe Travels! ⚡️ A few install pics- The Victron GX 70 touch screen fit the existing opening with no cutting or trimming of the fiberglass. Very happy with the touch screen and the Victron app. We can set the screen to time out at 5 or 10 min or longer and then go dark for sleep mode. Zamp 90W suitcase. 12v DC to DC Andersen connector. On our way home we camped at Cumberland Mountain SP in Tenn and gave our new system a shake down. It’s nice to not have to plug in. 😊

We recently were at Oliver, had a nice conversation with Scott, Jason Essary and Matt Duncan. We also had the opportunity to meet both of these new to Oliver folks. Just posting up for those who like to put a face with a name.

This may be of help. You will definitely need deep well sockets for the Ubolts.

Well done Ron. It’s has an OEM look! 👍🏻

Great pics and amazing how the wild fires can destroy a forest. Looks like beautiful weather there!
