Fireproof Charging & Safety Bag for E-Bike Batteries up to 750 Wh
Maximum Safety for Lithium-Ion Batteries During Charging, Storage, and Transportation
The fireproof bag for e-bike batteries has been specifically developed for the safe charging, storage, and transportation of modern lithium-ion batteries. This high-quality safety and charging bag is suitable for e-bike batteries up to 750 Wh and supports risk reduction in the event of thermal incidents such as battery defects or a possible thermal runaway.Unlike many simple “fireproof” bags, the construction is based on a uncompromising safety concept using 100% non-combustible high-performance materials. The bag features a multi-layer technical construction with integrated insulation layers as well as high-temperature-resistant components based on specialized silica fiberglass fabrics.
The construction has been designed for high thermal and mechanical loads and withstands temperatures of up to 1200 °C.
Our FFZ fire containment blankets are used wherever lithium-ion-powered vehicles are charged, serviced, parked, or integrated into industrial processes. Typical areas of application include logistics centers, high-bay warehouses, industrial facilities, workshops, charging zones, quarantine areas, and safety-critical infrastructure with increased fire protection requirements.
Developed for the Safe Charging of E-Bike Batteries
The fireproof bag has been specifically designed as a safety and charging bag for lithium-ion e-bike batteries. Thanks to the integrated protected cable feed-through, the battery can be charged directly inside the bag without leaving the protected area.
Especially during the charging process, increased risks may arise due to potential cell defects, damage, or technical malfunctions. The bag supports safer battery charging and provides additional protection for surrounding areas, living spaces, garages, workshops, basements, motorhomes, and camping environments.
The construction has been tested multiple times with 750 Wh e-bike batteries and additionally evaluated at the Fraunhofer Heinrich Hertz Institute.
100% Non-Combustible High-Performance Materials
Only non-combustible high-temperature materials are used for the construction of the fireproof bag. The multi-layer technical design combines high-performance silica fiberglass fabrics with additional thermal insulation layers to increase temperature and pressure resistance. The materials used are characterized in particular by the following properties:
- Absolutely non-combustible components, including the closure system
- Temperature resistance up to 1200 °C
- High thermal resistance
- Multi-layer safety construction
- High pressure resistance
- High-quality technical workmanship
- Additional insulation layers for thermal shielding
- Robust and durable construction

Premium Design and Professional Workmanship
In addition to its technical safety performance, great emphasis was also placed on a premium, modern, and functional design. The fireproof battery bag stands out through its professional workmanship, durable construction, and distinctive appearance.
The bag is suitable for both private use and professional applications in the fields of e-mobility, service, workshops, outdoor activities, camping, and transportation.
Preventive Fire Protection for Modern E-Mobility
With the increasing use of high-performance lithium-ion batteries, preventive fire protection is becoming more important than ever. The fireproof battery bag provides a high-quality safety solution for increasing fire protection when handling e-bike batteries and supports the safe storage and charging of modern energy storage systems.
The combination of non-combustible high-performance materials, temperature-resistant multi-layer construction, and professional workmanship makes this bag a particularly high-quality fireproof charging and safety bag for lithium-ion e-bike batteries.
When a Battery Goes Into Thermal Runaway – Real-World Test Demonstrating the Fire Dynamics of Lithium Batteries
To demonstrate the actual risks of a damaged lithium-ion battery, an e-bike battery was intentionally triggered into thermal runaway under controlled conditions at the Fraunhofer HHI. The video uncompromisingly demonstrates the destructive energy of a thermal runaway event and shows the extreme forces our fireproof battery bags are designed to withstand. A clear and authentic demonstration for increased safety when handling lithium batteries.

In this test conducted at the Fraunhofer Heinrich Hertz Institute, an e-bike battery was intentionally triggered into thermal runaway under controlled conditions – this time fully enclosed inside our fireproof bag for lithium-ion batteries. The video realistically demonstrates the extreme temperatures, pressure impulses, and flame reactions occurring inside the bag and shows how effectively the construction absorbs and contains this energy.

This uncut thermal runaway test shows the controlled reaction of a 635 Wh e-bike battery (SOC 100%) fully enclosed inside our fireproof bag for lithium-ion batteries.
During the test, extreme temperatures, powerful pressure impulses, intense flame reactions, as well as significant smoke and gas development occur – typical characteristics of a fully failing lithium-ion battery. The video documents the complete process without interruption to ensure full transparency.
Despite these extreme conditions, the fireproof battery bag remains completely stable:
- No flame or jet-stream release
- No ejected particles or battery fragments
- Effective containment of pressure, gases, and thermal energy
- Structural integrity maintained throughout the entire thermal runaway process
The results clearly confirm: Our fireproof lithium-ion battery bag reliably contains a complete thermal runaway event, prevents the uncontrolled spread of fire and debris, and provides valuable time to safely isolate and move an unstable battery to an outdoor or secure area.
