Maximum Capability
The Highest Capacity.
The Same Uncompromising Safety.
The Model XXL delivers everything that makes BUNCKER® the global standard for lithium battery transport safety at the largest scale available in the Pro Line Heavy. No other certified packaging solution accommodates more energy or more mass.
Thermal Runaway Containment
Full structural containment of thermal runaway events in assemblies up to 200 kWh. The XXL housing is engineered for the highest internal pressures and temperatures in any Pro Line Heavy model validated under UN testing protocols.
HF Gas Filtration
High-capacity hydrogen fluoride filtration system matched to the internal volume of the XXL model. Ensures complete neutralisation of toxic off-gas emissions during containment events, fully compliant with IMDG, and ADR requirements.
Forklift Accessible
Heavy-duty four-way forklift pockets are rated for the full loaded gross weight of the Model XXL. Compatible with standard warehouse reach trucks, counterbalance forklifts, and port heavy-lift equipment.
Stackable Design
ISO-compatible corner castings allow verified stacking in standard 40-foot containers and high-cube units. Maximises container utilisation and delivers significant logistics cost savings at scale for BESS and EV fleet operators.
