One of the most common questions we hear is simple: do I need a fire blanket, an extinguisher, or both? The honest answer is that they are not competing products. They do different jobs, and for a lithium-ion battery fire each handles part of the problem the other cannot.

01What an EV fire blanket does

An EV fire blanket is a large, high-temperature textile designed to be deployed over a burning vehicle, battery or device. Its job is containment: it smothers open flame, starves the fire of oxygen, traps the bulk of toxic smoke, and shields the surroundings from radiant heat. That last point matters in a garage, carpark or workshop, where the immediate danger is often fire spreading to nearby vehicles, walls or stock.

What a blanket does not do is reach inside the battery to stop the chemical reaction. As Fire and Rescue NSW (2025) notes, stranded energy in undamaged cells can keep a battery hot and prone to reignition. A blanket contains the consequences while that energy works through — it is a barrier, not a cure.

02What a lithium-ion extinguisher does

A lithium-ion rated extinguisher attacks a different part of the problem: cooling. The agent is formulated to draw heat out of the cells and interrupt the runaway process at the source. Extinguishers manufactured to recognised standards such as EN 3-7:2004+A1:2007 (European Committee for Standardization, 2007) are independently rated for performance and reliability, which is the assurance you want from a device you may only ever use once.

The limitation is range and capacity. An extinguisher must be used at close quarters, and a single unit holds a finite charge. Against a fully involved vehicle pack it may not be enough on its own — which is exactly why pairing matters.

03Why a layered setup wins

Picture an e-bike beginning to vent and smoke in a hallway. An extinguisher lets you cool the battery early, before flames take hold. If it escalates, a blanket lets you cover the device and contain smoke and spread while you evacuate and wait for Fire and Rescue. Each tool covers the other's blind spot. This layered approach is the principle behind our bundles, like the EV Fire Safety Bundle — 1L Extinguisher + E-Blanket, which packages a EV Fire Extinguisher 1L (E-Bike & E-Scooter) with a matched EV Fire Blanket (E-Bike & E-Scooter) for micromobility settings.

04Matching the gear to the asset

Size is the deciding factor. An e-bike or e-scooter is well served by a 1 litre extinguisher and a compact blanket. An electric car needs a full-size blanket such as the EV Fire Blanket (Electric Car) and the greater capacity of the EV Fire Extinguisher 4L. The principle stays the same across the range — cool the source, contain the spread — only the scale changes.
