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 heating, the air conditioning, the lights and the fridge, all at once when needed, backed by a high continuous discharge current. And it works with the equipment you already have: the Epsilon is highly compatible with all leading component brands, plug and play in virtually any system.

Quality cells, precision-matched

High-grade 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.

Connected and in control

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.

Made for every season

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.

Reliable power for your aquatic journey

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.

Optimal comfort and safety

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.

Lithium advantages for leisure marine

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.

Fast Charging for Longer Adventures

Spend less time charging and more time on the water. Super B lithium batteries can fully recharge within one hour, giving you the freedom to extend your journey without compromise.

Low Self-Discharge for Peace of Mind

Store your boat over long periods without worry. With a 10x lower self-discharge rate than lead-acid batteries, Super B lithium batteries are ready to power your next adventure whenever you are.

Built to be trusted

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. Super B's proprietary software continuously monitors for anomalies, responds when needed, and records every event in the integrated data logger.

Built in Europe
Designed, built and tested in Europe: precision cell matching, thermal management and proprietary software that holds across extremes, and mechanical robustness that shrugs off vibration, shock and heat.
