Designed for large-scale domestic and professional mowing applications, this advanced 56V ePower Pro battery delivers exceptional runtime, intelligent power management and robust durability for demanding mowing conditions.
Developed as part of the STIGA ePower Pro modular battery system, this battery is designed for use with compatible battery garden tractors, providing scalable runtime, swappable convenience and professional-grade performance. With advanced thermal management, sealed construction and smart battery monitoring, it offers a premium power solution for users managing large lawns and estates.
Key Features
High-Capacity 56V Lithium-Ion Power
The battery features 56V output, 40Ah capacity and delivers approximately 2,000Wh of stored energy, providing substantial runtime for demanding mowing applications.
Designed to provide:
- Consistent high-output performance
- Fade-free power delivery under load
- Long runtime for large-area mowing
- Professional-grade energy storage capacity
STIGA ePower Pro Modular Battery System
This battery is part of STIGA’s modular ePower Pro system, allowing operators to scale runtime depending on the application.
Performance potential includes:
- Single battery: coverage up to 7,500m²
- Dual battery setup: coverage up to 15,000m² (machine dependent)
- Swappable design for extended or near-unlimited runtime with additional batteries
This makes the system highly flexible for larger properties and commercial use.
Advanced Battery Management System (BMS)
An integrated smart Battery Management System (BMS) continuously monitors:
- Cell balance
- Voltage stability
- Temperature management
- Charge and discharge optimisation
This helps maximise battery lifespan while maintaining consistent performance under heavy load.
Advanced Thermal Management
The ePower Pro battery incorporates Phase Change Material (PCM) cooling technology, designed to absorb and regulate heat generated during operation.
Benefits include:
- Improved performance under sustained load
- Better temperature stability
- Enhanced cell protection
- Extended battery longevity
This makes the battery particularly well suited to demanding professional mowing applications.
IP65 Sealed Aluminium Construction
Unlike many conventional battery packs, the ePower Pro features a fully sealed die-cast aluminium body with IP65 protection, offering resistance against:
- Dust ingress
- Moisture and water spray
- Outdoor debris
- Daily commercial wear
The rugged housing also contributes to structural strength and cooling efficiency.
Fast Charging Capability
The battery supports rapid charging with compatible chargers, with recharge times of approximately 2.5 hours (charger dependent).
This helps minimise downtime and improve productivity.
