Purpose-Built Marine Battery Solutions

Our batteries are engineered for marine conditions and matched to your specific outboard model and boating needs. Available capacities include smaller packs for lightweight use through to larger kWh options for extended outings or bigger vessels.

Each battery features:

Minimal self-discharge during storage so your battery stays ready when you are

Lithium-ion chemistry for high energy density and long life

Fully enclosed metal casing with lifting handles for safety and portability

LCD display and usage meter for easy trip planning

Compatibility with future battery upgrades

Typical charging from standard 240V mains in about two hours

Designed for Performance & Ease

Battery capacity directly influences your available run time — generally, the more kWh you choose, the longer you can enjoy mixed-speed boating without needing to recharge. EClass batteries integrate seamlessly with our outboards, using a high-voltage (96 V DC) system that improves efficiency, increases power delivery and extends run times on the water.

All batteries include a user-friendly display for real-time charge and range monitoring, helping you plan your trips with confidence.

Reliable, Long-Life Power

Our marine battery systems are tested for reliability and longevity, with warranties that reflect their robust design. While electric outboards represent an upfront investment, charging costs are typically lower than petrol fuel, and the batteries retain charge well in storage between outings.

Battery Options & Customisation

We offer a range of battery sizes — from smaller 3 kWh packs through larger 20 kWh and 30 kWh options — to suit different vessels and usage profiles. Whether you’re after extended range, heavier loads or hybrid setups, we can recommend the ideal combination for your boat.

Why EClass Batteries Stand Out

Upgradeable technology as battery innovation advances

Marine-ready build quality with corrosion-resistant casings

Fast recharge from standard power sources

Portable and easy to stow on board

Display and trip-planning tools included
