The motorhome energy battery, done right. Now in six models.

The updated Epsilon range
The Epsilon is the backbone of the Super B range: years of engineering refined into a battery that does exactly what a motorhome asks of it, and keeps doing it for years.
It runs the kitchen, the heating, the lights and the fridge, without ever making you think about the power behind it.Now that same battery comes in more capacities, so you can match it to your setup instead of building your setup around it.
Nothing about the Epsilon was left to chance. The details that make it dependable are the same ones you'll never have to think about again.

High-grade prismatic LiFePO4 cells, carefully matched for balanced performance across the whole pack. Backed by more than 5,000 cycles, it holds its capacity long after ordinary batteries have faded.
Connect over Bluetooth to the Be In Charge app for live charge, temperature and history, all from your phone. Firmware updates add new features over time, so the battery keeps getting better.

Nine temperature sensors and an intelligent self-heating system keep the Epsilon safe and performing in the cold, charging down to -30°C. Deep winter or summer heat, it doesn't miss a beat.
Six models, one proven platform.
Pick the capacity that fits your setup, and get the same engineering in every one.
Whether you sail, navigate, race, or fish for fun or professionally, having reliable power is essential. Super B lithium batteries provide long-lasting, dependable energy for all types of vessels. With lithium iron phosphate technology (LiFePO4), you can navigate independently, free from noise, vibrations, or exhaust fumes.
Leisure boats and yachts prioritize comfort and safety. Super B lithium batteries enhance your onboard experience by providing silent, reliable power. Enjoy beautiful harbors and spots with no noise, vibrations, or exhaust fumes, ensuring a stress-free aquatic journey.
Super B lithium batteries are engineered for durability and safety. They charge quickly, discharge slowly, and hold their charge longer than lead-acid batteries. With a higher energy density, they require less space and weight—perfect for leisure marine applications.
Besteed minder tijd aan opladen en meer tijd op het water. Super B lithiumbatterijen kunnen binnen een uur volledig worden opgeladen, waardoor u de vrijheid hebt om uw reis zonder compromissen te verlengen.
Berg uw boot zonder zorgen langdurig op. Met een 10x lagere zelfontladingssnelheid dan loodzuuraccu's, zijn Super B lithiumaccu's klaar om uw volgende avontuur van stroom te voorzien wanneer u dat ook bent.
The Epsilon is engineered to the last detail, tested against the extremes and proven across years of travel, so it becomes the part of your setup you never have to think about.
Protected on every level
Advanced cell balancing, overcurrent and short-circuit protection, over- and undervoltage protection, high and low temperature protection, over-discharge protection, and terminal thermal protection that detects loose cable connections.
Engineered in Hengelo
Designed, built and tested in the Netherlands, with the same engineering Super B proved in motorsport: precision cell matching, thermal management that holds across extremes, and mechanical robustness that shrugs off vibration, shock and heat.
