Dutch company Epsilon solves RV battery limitations


New Epsilon lithium RV battery

By Bob Difley

A new lithium battery, developed by Dutch battery expert Super B, offers campers and boaters huge power and energy reserves, so people no longer have to worry about energy provision, charging points or limited power. The Epsilon weighs substantially less and will last five times longer than conventional batteries, is fully charged within one hour and has more energy than ever before.

Thus the battery allows people to enjoy the freedom of their camper or boat in a hassle-free and relaxed manner, while they can use multiple appliances simultaneously.

Battery limitations are one of the most annoying problems for people who are heading out with their camper or boat. There is nothing worse than undertaking a trip and continuously worrying about the energy provision. It’s not only annoying, it also limits their freedom.

This is something Super B understands only too well. While Tesla is developing new super batteries for electric cars or solar-powered homes, Super B comes with a new and advanced energy storage solution for boats and campers. For carefree traveling, the company has developed the Epsilon SB12V1200Wh-M, a user-friendly and custom-made lithium battery. Thanks to its light and ultra-compact format, it fits into the space of a traditional lead battery, but weighs about 20 kilograms less. Even under extreme temperatures it will continue to work without any problems.

Its high capacity can power coffee machines, air-conditioning and other devices that could not be powered from traditional batteries, all at the same time. So people in their camper or boat can watch TV and prepare a pot of coffee while the air-conditioning provides some cooling. Worrying about how long the battery will last is no longer necessary.

Besides more energy, far less weight and an ultra-compact format, the Epsilon has a lot of practical advantages. Monitoring the exact state of charge by using an app on their smartphone or tablet, people can get insight into the remaining energy level at all times. A low self-discharge of 10 percent per year allows them to use their camper or boat even after several months of storage. Also the battery is maintenance free.

It only weighs 12.5 kilograms and the life of the Epsilon equals 5000 cycles, which is five times more than traditional batteries can offer. Furthermore, greater than 96% efficiency means more efficient (solar) charging and using almost all available energy.

    Oh, I neglected to add in my previous comment that in Jan 2016 I installed 400AH of lithium battery & 650Watts of solar panels in/on my motorhome. While I am not an expert, I do have experience with lithium batteries and dry camping.

  2. Al & Sharon

    Wow! The sales hype in this article is amazing. Don’t overlook the implication that you can power your air conditioner with this battery, and then goes on to say the battery weighs only 12.5 kiograms. That is less than 30 pounds.
    An article like this makes me wonder if you are getting paid to promote this battery.
    While the battery may be a fine Lithium battery, the description is nothing but hype!

    1. Bob

      I have sent your comment to the battery manufacturer requesting a response
      . I don’t know whether I will receive a reply, but if I do I will post it.

      1. Bob

        Today I received a response from Marloes Eshuis,
        Marketing Manager of the Super B company in the Netherlands regarding a comment made by Al & Sharon regarding the “sales hype” of the company’s battery.

        Dear Bob,

        Thank you very much for posting our article online and for your interest shown in our battery!

        To answer the question: This battery is specially designed for use in recreational vehicles. And yes, indeed, it can definitely be used to power the air conditioning, even though it only weighs 12.5 kilograms. Of course, it is hard to tell for how many hours, because that depends on the system you have, the other devices you use simultaneously, etc. etc. Your local dealer can help identify your personal consumption requirements to make sure you get the best energy storage solution for your situation.

        Mastervolt (http://www.mastervolt.com/) is our partner in the US. They offer a large dealer network and local support and are happy to help.

        If you are interested, more technical details on the battery can also be found on our website: http://www.super-b.com/epsilon

        Please do not hesitate to contact us if you need any further information.

        Kind regards,

          Typical marketing baloney. Do the math on the draw of any a/c system. He should have told the truth, but, instead, he thought more double speak was in order.
          I suggest, he reply with the most conservative estimates, rather than just pass it off with a non answer.

          Wait, i’ll answer it for him, look at his title “marketing manager”. How many engineering courses do you think he has under his belt to even attempt to broch the topic. Ans. 0

          Proof; electrical terms are universal, if he was honest,he would have deferred this technical question to their engineering and product development division.

          Instead, typical non-answer, by an unqualified individual.

      2. Al

        Thanks for sending my comments to the Mfg. Well the answer seems to be just about what I expected to get from them. While, “Yes the 25-30 pound lithium can power a 13,000 BTU air conditioner”, just not for very long. Not discussing the startup current draw, a running air conditioner pulls about 15 amps of 120V AC power. Inverting the 12V DC from the battery would require about 150amps of DC power. Assuming the 25-30 pound battery would be rated at about 100AH, it would power the air conditioner for about 30 minutes. However at the end of that 30 minutes you are left with no reserve power in the battery to run your lights, water pump, etc until you recharge the battery.

        There have been a couple of blog entries I have read where they have run their air conditioner off of lithium. Typically for just 2-4 hours. However they have systems with around 600-800AH of battery and a 1000-1400 watts of solar. When they did run the air conditioner, they had good sun light so the drain on the battery wasn’t as significant as if it was just the battery supplying the energy w/o being recharged at the same time.

    I don’t at all mind advertisements on this site. I want RVTravel to stay in business, and I’m glad to learn about products I might want or need. However, this is the second instance I’ve noticed of an advertisement disguised as an “article.” If you’re going to tout a product, I’m all for it. It that’s all you’re doing, show it as an ad. It you want to make it an “article,” then it behooves you to tell us why it’s better than another product just like it and why it worth the price. I read all the specs on their site and I can’t see how it is different from other similar lithium batteries. Searching for a cost, I finally found the Super B – 12v Lithium Battery (LiFePO4) – SB12V160E-ZC at $ 3,279.00.

    1. Bob

      There are several reasons why the Super B battery post was not an advertisement. (1) The selection of products to post are solely the picks of the poster, most of which are mine, and not selected by Chuck or the staff at RVTravel. (2) For something to qualify as an advertisement it must involve some kind of remuneration. In this case there was no payment or other consideration for posting about the battery, in fact, Super B was not aware that we had posted it (unless they read the newsletter) and I had no contact with Super B before posting the product. (3) Part of the purpose of the Great RV Accessories newsletter, and Gadgets & Gizmos is to find and post new product information, much of which comes from press releases from the manufacturer or its PR firm, and we do not have a product to evaluate. (4) If a product you find in the newsletter was personally reviewed then that would be evident from the writing, usually by use of the first person voice, and also reference to actually using the product. (5) When product information is posted that comes from a press release you will find the words “Information obtained from press release” at the bottom of the post, and such a post is not meant to be an endorsement. RV Travel posts one of the most transparent information websites that you will find on the Internet. You can go back and read Chuck’s editorials explaining why he rejects many advertisers as he will not allow the information posted in any of the newsletters to be influenced by advertisers’ interests.

      1. William Jeracki

        Bob, I think you are missing the point. Just because no one recieved remuneration, doesn’t mean your posting didn’t promote a specific product. What is being talked about in the replies: The Super B battery. You print a Press Release with a headline that claims to have solved all the limitations of Lithium technology so it is safe for the average RV use to to just drop in their rig a go. This may or may not be a good product, I don’t know and certainly you don’t know. My problem here is that you promoted a single product that that is not the first and is not unique. By defending this cheap space filler for your article as not advertsing severely damages your credibility, not RV Travel

        1. RV Staff

          OK, William. I need to jump in here, although Bob can certainly “defend” himself and his articles (which he shouldn’t have to do). He presented this Press Release to get the information out there to our readers about this product — in case anyone is interested. Of course a Press Release from a company is going to promote their product — that’s what they’re for. Since Bob hasn’t tried this battery, he can’t write a review about it. By reading the Press Release, readers can come to their own conclusions about the product, do further research if they’re interested, and compare it to similar products. Of the more than 1,800 people who have read Bob’s article/Press Release today, there (so far) have been 20 comments, and only 4 people have had negative comments — mainly upset because they see this as “advertising.” Yes, it’s advertising from the company — but it’s presented to our readers for their information. Period. It’s not necessary to jump all over Bob for posting a Press Release. “Cheap space filler”? It’s information. Don’t like it? Don’t read it. — Diane at RVtravel.com

          1. Kristy

            I agree with Diane. I for one was really excited to read this article; it got me hooked on upgrading to Lithium batteries. I might buy the Super B or another brand, I haven’t decided yet. I don’t think RV owners are so gullible as William suggests.

  4. William Jeracki

    Why are you featuring a press release on a European product that makes it sound like they are the first to offer a drop-in lithium 12volt replacement battery? High quality lithium 12volt batteries that can be used to replace our typical Group 27 lead based battery have been available for several years. Most of these are designed and manufactured in the USA. The key to making these a safe drop in is the Battery Management system. The good ones will allow charging with most Converter Charges designed for lead batteries, but you don’t get a full charge. Lithium Batteries are best maintained with a constant current- constant voltage charger at 14.6 volts. These are really simple charges compared to the “smart” chargers used on lead batteries these days.

    1. Bob

      I do not like to change the text of press releases unless I am sure that the information I add is accurate or relevant. The Super B battery information was unchanged from the press release, describing a new product that we did not have to test, yet felt that it was relevant as a new product announcement.

      1. George Barr

        Nothing is worse for a drop in LiFePo4 battery than leaving it on 14.6V after it reaches full charge. Suggest those thinking of a purchase of “drop in” LFP’s read this by a disinterested testing guy who has no commercial interest in selling them http://www.pbase.com/mainecruising/lifepo4_on_boats

        1. Bob Difley

          Thanks George for that link to an expert’s opinion (and quite detailed explanation) of Lithium Ferrous Phosphate (LFP) batteries. For anyone interested in this developing type of battery I suggest reading it. Here again is the link: http://www.pbase.com/mainecruising/lifepo4_on_boats

    Looks like my question(s) have been answered in part.

  6. Bill Semion

    Looked at their website and so far, see no dealers for camper-style batteries, so have no idea about the price of these. Question: If I have two six-volt lead batteries, how difficult is it to convert to one 12-volt? Probably not much, possibly just removing the bridge cable, but just curious. Thanks

  7. Drew


    You’ll need a different converter/charger if you are replacing lead acid batteries with lithiums….depending on your needs this could add several hundred dollars to this change…just fyi

    1. Tina GAllagher

      Drew, you just answered a question for me about converters. Would switching to these also mean I have to have a different charge controller for my solar system and a different power panel with a different battery maintaining system?

      1. Drew

        Hi Tina,

        It depends- lithiums need a charge that is like a “maintain” mode. That is where they do best. They will accept higher voltages and higher amperage but within reason. Lithiums also need to be placed where they will not freeze or approach freezing temps. In your solar application they are superior to lead acid batteries by far. As long as your controller is programmable- you should be fine. There is lots of great info on the web about lithium batteries and solar applications.

  8. tom Hudson

    sounds great. Do you have any info on the cost
