Portable 1,200 W battery system for construction tools.

CONTEXT

The client needed to operate construction and carpentry tools inside buildings before an active grid connection was available.

The system had to support demanding power-tool loads while remaining compact enough to carry between different work areas.

Engineering Approach

EION configured an 800 Wh lithium battery system using high-density NMC cylindrical cells selected for high-discharge operation.

The resulting architecture combines 1,200 W output, dual AC connections and a portable enclosure with an integrated handle.

USB connections and Bluetooth monitoring were also incorporated to support everyday operation and system visibility.

System Configuration

• 800 Wh lithium battery system
• 1,200 W output for compatible high-demand tools
• High-density NMC cylindrical cells
• Dual AC outputs
• Integrated USB-A and USB-C ports
• Portable enclosure with carrying handle
• Bluetooth connectivity with mobile app monitoring
• Dimensions: 350 × 280 × 80 mm
• Weight: 7.8 kg

Outcome

OHM enables selected construction and carpentry tools to operate in buildings and work areas without an active grid connection.

Its compact format makes the system practical to move between work areas, while Bluetooth monitoring provides visibility into its operating status.

Professional off-grid power, engineered around the tools and the work environment.
