Battery storage box CoreParts FIREBAG-L, fire-resistant containment for small batteries, 115×75×165 mm, black/grey

CoreParts FIREBAG-L is a compact, fire-resistant storage box designed to contain and isolate small batteries. Measuring 115×75×165 mm and finished in black/grey, the enclosure is intended to reduce risk during storage and transport of single-cell and small multi-cell lithium batteries and related accessories. Constructed from flame-retardant fiberglass material with internal and external protective layers and a Velcro closing system, the unit offers improved containment for incidents such as overheating or localised ignition, while remaining lightweight and portable for workshop, lab or travel use.

Advantages

The FIREBAG-L combines high-temperature resistant fiberglass layers with a secure Velcro closure to provide a practical containment solution for small Li-ion batteries. Its compact dimensions suit interim storage and transportation needs, and the layered PROTECTIV material construction increases resistance to heat and direct flame exposure. The product is intended to limit the spread of fire and contain debris from battery failure, offering an accessible safety measure for daily use.

Suitable for

• Single-cell and small multi-cell lithium-ion batteries
• Battery packs and charging accessories during transport
• Interim storage in workshops, laboratories or on-the-go
• Containment during D-Tap charging and other field charging scenarios

Key specifications

• External dimensions: 115 × 75 × 165 mm
• Colour: black/grey
• Construction: multi-layer flame-retardant fiberglass material
• Closure: Velcro fastening for quick opening and secure closing

How to use

Place the battery or battery pack inside the FIREBAG-L so that there is no direct mechanical stress on the cells, then close the flap securely using the Velcro fastening. Use the bag on a stable, non-combustible surface while charging or storing batteries and keep the item under occasional observation when charging. Do not place the bag near open flames, intense heat sources or inside sealed consumer luggage where ventilation is restricted. After any incident or visible damage to a battery, allow the bag and contents to cool and ventilate before handling and follow local regulations for disposal of damaged batteries.

Usage recommendations

FIREBAG-L provides an additional layer of containment but does not guarantee complete protection in the event of thermal runaway or catastrophic battery failure. Use as part of a broader safety routine: inspect batteries before use, avoid overcharging, use compatible chargers, and follow manufacturer guidance for storage and transport. For larger battery packs or long-term storage, consider certified containment solutions appropriate to the battery type and scale.
