Stiga 40Ah ePower Pro Battery

The STIGA 40Ah ePower Pro Battery is the high-capacity power source designed for STIGA’s professional electric mowing platform. Built with 40 Ah high-density lithium cells and a rugged die-cast aluminium body, it delivers the sustained power required by larger machines such as STIGA battery garden tractors and professional mowing equipment. The result is strong, consistent output during demanding mowing work without the noise, servicing or fuel costs associated with petrol-powered machines.

As part of STIGA’s modular ePower Pro system, the battery can be used individually or combined with additional batteries to extend runtime depending on the machine and the size of the area being maintained. The STIGA ePower Pro 40Ah battery also supports both on-board and off-board charging, making it easy to manage charging cycles and store batteries safely when not in use. Suffolk Mowers supplies the full STIGA battery ecosystem, ensuring compatibility advice, parts support and servicing when needed.

STIGA 40Ah ePower Pro Battery Overview

The STIGA 40Ah ePower Pro battery is built to power the largest machines in the STIGA electric mowing range. With a substantial 2000 Wh energy capacity and 56V output, it provides the sustained power required by ride-on tractors, front mowers and professional robotic systems. The design focuses on consistent output under heavy load, which is essential for machines cutting large areas or operating for extended periods.

Unlike smaller garden tool batteries, the STIGA ePower Pro system is designed as a modular energy platform. This allows batteries to be swapped, combined or rotated depending on the runtime required. For owners of battery tractors such as the STIGA Tornado series, the 40Ah battery forms the core of the machine’s power system.

High-Capacity Power for Large Machines

The STIGA 40Ah battery uses high-power-density lithium cells engineered to maintain stable power delivery from the beginning of a job through to the final cut. This is particularly important on larger machines where cutting performance must remain consistent across wide decks and long mowing sessions.

• 40 Ah battery capacity
• 56 V operating voltage
• 2000 Wh total energy capacity
• Stable power delivery for demanding mowing work

This capacity makes the STIGA 40Ah ePower Pro battery suitable for machines that require sustained output rather than short bursts of power.

Modular Runtime System

A defining feature of the STIGA ePower Pro platform is its modular design. Batteries can be used individually or combined depending on the machine and the area being maintained. For example, STIGA battery tractors often run one or two batteries depending on the mowing area.

• Use single batteries for smaller areas
• Add additional batteries to extend runtime
• Swap batteries between machines within the STIGA Pro ecosystem
• Maintain continuous working capacity by rotating batteries

This modular approach gives owners flexibility as their needs change and allows businesses to run multiple machines from the same battery platform.

Engineered for Durability

The STIGA ePower Pro 40Ah battery uses a die-cast aluminium housing rather than the plastic casing found on many garden machinery batteries. This construction improves structural strength while also helping dissipate heat during operation.

The sealed design is rated IP65, protecting internal components against water and dust. This is particularly useful for professional users who operate machinery outdoors in varying weather conditions.

• Die-cast aluminium battery housing
• Sealed IP65 design against water and dust
• Strong locking system to secure the battery in the machine

The solid construction helps the battery withstand regular installation and removal across multiple machines.

Advanced Thermal Management

Managing heat is critical for maintaining battery lifespan and performance. STIGA integrates Phase Change Material (PCM) within the battery to stabilise internal temperatures when the battery is working under load.

This material absorbs excess heat produced during discharge and helps maintain consistent operating temperatures inside the battery pack. The result is improved efficiency and longer-term battery health.

A smart Battery Management System (BMS) also monitors voltage, temperature and cell balance to maintain safe and efficient operation throughout each charge cycle.

Flexible Charging and Storage

The STIGA 40Ah ePower Pro battery can be charged directly on the machine using the STIGA Pro Charger, or removed for off-board charging in a dry location. Many professional users prefer to rotate batteries between machines while charging spare units in the workshop.

This approach allows fleets of machines to run continuously without waiting for charging cycles to complete.

For winter storage or extended downtime, removable batteries can be kept in temperature-controlled environments while machines remain in storage areas or equipment sheds.

Compatible Machines

The STIGA ePower Pro battery system is designed to power several machines within the STIGA professional electric platform. Examples include:

• STIGA battery garden tractors including models such as the Tornado 398e
• STIGA ePark Pro articulated front mowers
• STIGA APX Pro autonomous robotic mowers

This shared battery ecosystem allows operators to standardise power across different machines, reducing fuel costs and simplifying equipment management.
