Hermax HX-SB1 Safety Box/Charging Station + Tronje Aerosol Fire Extinguisher

This safety box was specifically designed for the safe storage and charging of lithium batteries—ideal for electric vehicles such as e-scooters, electric scooters, mobility scooters, pedelecs, and e-bikes. It is also suitable for numerous other lithium batteries, provided their size and capacity are compatible.

The robust steel construction with 40 mm ceramic fiber insulation provides reliable protection against heat and fire in an emergency. Tested according to EN 1363-1:2020, it offers 60 minutes of fire resistance. The integrated charging port allows for safe charging while the box is closed, without having to remove the batteries from the protective environment.

In addition, the safety box is equipped with a condensed aerosol fire extinguisher. This modern extinguishing system was developed specifically for enclosed spaces and activates automatically in the event of a fire when high temperatures are detected. Within seconds, the extinguishing aerosol spreads evenly throughout the interior of the box, helping to contain emerging fires at an early stage and reduce further spread. The pressureless system uses a non-toxic and non-corrosive extinguishing agent and offers a maintenance-free service life of up to 10 years.

For maximum flexibility, the box is equipped with four heavy-duty casters, two of which are lockable. This allows it to be moved easily and secured stably when needed.

Whether for vehicle and bicycle batteries, model-making, drone, or power tool batteries—the safety box creates a reliable charging and storage environment for both private users and commercial applications.
