With Green Cubes, you get more than just reliable power — you gain a partner committed to operational efficiency and uptime. Our unmatched support ensures your ground crew has the energy they need, shift after shift.



Benefits of Green Cubes’ Lithium SAFEFlex GSE Batteries

Built for GSE
SAFEFlex batteries are engineered specifically for the demands of airport ground support operations. Designed to perform reliably in harsh ramp conditions, our batteries include integrated heaters for low-temperature environments, wide temperature range support, and rugged enclosures to withstand vibration and outdoor exposure. Green Cubes also offers custom design capabilities, such as installing or integrating with an onboard charging system, tailoring solutions to meet the exact requirements of your fleet.

Safety & Reliability
Constructed from UL-approved components, SAFEFlex GSE batteries are engineered for the demanding conditions of the airfield. Voltage, current, and temperature are continuously monitored, with safety managed through integrated contactors. Using Lithium Iron Phosphate (LFP) — the safest chemistry in the lithium-ion category — SAFEFlex batteries deliver peace of mind for crews working around aircraft, passengers, and baggage.

Flexible Applications
SAFEFlex batteries power the full range of electric Ground Support Equipment, including:
- Baggage tractors
- Belt loaders
- Pushback tugs
- Catering trucks and maintenance lifts
Green Cubes batteries are designed to support both new OEM builds and retrofit projects, making our systems a fit for any GSE fleet modernization effort.

Energy & Cost Savings
With a recharge efficiency of over 98%, SAFEFlex batteries reduce electrical consumption and cut costs compared to diesel-powered GSE. Airlines also benefit from:
- Lower fuel spend
- Reduced downtime (no fueling delays or long charge times)
- Improved ramp efficiency that supports on-time departures

Plug & Play Integration
SAFEFlex batteries are drop-in replacements that connect through a simple single-point interface. Our batteries replicate the ease of lead-acid systems without requiring special modifications, allowing airlines to upgrade existing fleets without major rewiring or equipment changes.

Low Maintenance
Sealed and self-managing, SAFEFlex batteries require no watering, acid handling, or equalization cycles. The integrated Battery Management System (BMS) automatically monitors and optimizes performance. All critical electrical components are contained in an easily accessible Battery Control Module separate from the cell compartment, reducing shop labor and eliminating hazardous material handling for crews.
