More capacity, more freedom – without replacing your existing system.

The BOS LE300 is the smart lithium upgrade for your existing 12V lead-acid battery. Whether AGM, GEL, or wet cell – simply connect the LE300 to the positive and negative terminals and immediately benefit from additional capacity. No modifications to the charging system, no cable clutter: true plug & play. Simply choose the right size for your needs – from 28 Ah to 168 Ah.

Why the LE300 changes your electrical system

Conventional lead-acid batteries quickly lose performance when operated continuously without being fully charged – sulfation and limited cycle life often become noticeable after just one to three years. The LE300's intelligent battery management system (BMS) cleverly distributes load and charge cycles between the lead-acid and lithium batteries, extending the lifespan of both to up to 10 years . This way, you get the best of both technologies.

Safe travels – even in sub-zero temperatures

The integrated LiFePO4 cells are among the safest lithium cells on the market. They are thermally and chemically completely stable and protected by numerous safety features: overcurrent, overvoltage, short circuit, deep discharge, and reverse polarity protection are all standard. Thanks to integrated cell heating, the LE300 operates reliably down to -20 °C – perfect for anyone who wants to travel even in winter.

Modular and scalable – grows with your plans

Need more capacity later? No problem. Multiple LE300 modules can be connected and expanded at any time. Each module has its own BMS, ensuring your system remains redundantly protected. Even large peak loads are reliably covered by the combined use of lead-acid and lithium batteries – without limitations or unexpected system shutdowns.

Compact, lightweight, flexibly mountable

The LE300 modules are intentionally compact and lightweight. They fit even in tight installation spaces and can be mounted horizontally, vertically, or vertically – you decide where they fit best. Compared to a pure lead system, you save a significant amount of weight.

  • June Promotion: 15% off Eurobar Front Bars and ETB Side Steps

    Juni Aktion: 15% auf Eurobar Frontbügel und ETB Trittstufe

    Hey everyone!

    Summer is coming, and with it, the desire to improve your Grand California, Crafter or TGE. That's why we've picked out two parts for June that we really like, and we're giving you 15% off for the entire month. With the code ZMALPHA, you'll get the discount directly in your shopping cart.

    🛡️ Metec Eurobar Front Bar (VW Crafter and MAN TGE from 2017)

    A front bar not only looks great, but it can also do more. In tight parking spaces, on forest paths or in dense city traffic, the Eurobar absorbs the first impacts before they hit your Crafter or TGE. Made of 1.2 mm thick stainless steel tubing with a 70 mm diameter, matte black and with a vehicle-specific design for quick installation. It comes with EC type approval, so you don't have to worry about registration.

    🪜 AlphaDynamik ETB Swivel Step (Grand California)

    Tired of the original Thule step on your Grand California? Then this is your upgrade. 240 kg load capacity, LED lighting as standard and a smart swivel mechanism for the ideal entry height. The best part: We rely on the original AlphaDynamik control unit, so all functions are retained, including anti-trap protection and workshop mode. Our integration module is completely waterproof and sits protected under the driver's seat. Installation like from the factory, without loose cables and without provisional connections.

    What you need to know

    The 15% discount is valid until June 30th at 11:59 PM for exactly these two items. Simply enter the code ZMALPHA in the shopping cart and the discount will be applied. After that, prices will return to normal. So if you've been eyeing one of these parts for a while, now's the time.

    👉 Check out the shop and get your upgrade

    Best regards, Your ZM Team


    Please note: Depending on the order quantity, there may be delays in the delivery date. A subsequent discount is not possible; the code must be entered directly in the shopping cart when ordering. Payment via PayPal is not available for these two items; all other payment methods can be used as usual.

  • We're taking a break, but first, here's something for you!

    Wir machen Pause, aber vorher gibt's noch was für euch!

    Hey everyone!

    We have a small announcement for you: We're taking a break from April 20th to May 24th. We have some exciting things coming up in the next few weeks. We are preparing for our meeting, which requires our full energy. Also, our guided winter tour is still on the agenda, and there's a lot to plan for that. To get all of this properly organized, we're putting the shop on pause for now.

    But don't worry, the shop will remain open, and we won't let you leave without a small gift 😄

    🚀 New products during the break! Even though we're on a break, things remain exciting in the shop! We'll be launching several new products during this time, including care products and much more. So it's worth checking back regularly and browsing. And the best part: You can, of course, use the discount codes directly on the new products!

    📦 Orders before the break: All orders received by April 19th will be shipped before the break. Exceptions are items with longer delivery times, such as the Ecoflow Alternator in the Grand California Edition. In such cases, shipping can only take place after our return.

    Your discounts during our break:

    🖨️ 15% off all 3D printed items with code: 3DFrühling 🛒 10% off everything else in the shop with code: Springbreak

    Simply enter the respective code in the shopping cart, and the discount will be automatically applied. Please note: Subsequent discounting is unfortunately not possible. The code must be entered by you directly when placing the order.

    This promotion is valid only from April 27th to May 24th. After that, prices will return to normal. So if you've had your eye on something for a while, now is the moment.

    What you need to know:

    📧📞 No support by email and phone During our break, we will not be available by email or phone. As soon as we return, we will process everything. Feel free to write to us anyway, and we will get back to you as soon as possible.

    📦 Delivery times are incorrect Very important: The delivery times displayed in the shop are not valid during our break! We cannot process orders during this time. After our return, items will first need to be ordered or manufactured. All orders will then be processed in sequence. This means it may take a little longer than you are used to from us. But don't worry, every single order will reach you 🤝

    💳 No PayPal during the break We unfortunately have to inform you that payments via PayPal are not possible during our break. The reason is simple: In the past, we unfortunately had a few instances where cases were opened with PayPal during our absence claiming that goods had not been shipped. Since we cannot ship during the break, this only caused us unnecessary trouble and effort. We hope you understand. All other payment methods are, of course, available to you as usual.

    Why is it still worth ordering now?

    It's simple: The discounts are only available now, and new products are even being added. Those who order now secure the best prices and are directly in the queue when we get back to work. Those who order first also get delivered first.

    👉 Shop now and save

    We look forward to your orders and will get back to you as soon as we are back. Enjoy the time and see you soon!

    Best regards, Your ZM Team
