SeaNXT Elite Fireproof Transport Box — Overview
The SeaNXT Elite Fireproof Transport Box is the safety-engineered storage and transport case for the SeaNXT Elite underwater scooter and its 48 V / 24 Ah lithium-ion battery. A reinforced aluminium body combined with treated EVA plate inserts contains heat in the unlikely event of a thermal incident — the standard transport solution for lithium-ion packs on yachts, charters and shipping.
For short-distance scratch protection (yacht garage to swim platform) the Elite Carry Bag is more practical — but for on-board storage and any long-distance or shipping use, the Fireproof Transport Box is the safer choice.
Aluminium Body with Treated EVA Inserts
Reinforced aluminium walls contain pressure; treated EVA plates absorb heat. Together they prevent heat propagation outside the box during a thermal incident.
Lithium-Ion Containment
Lithium-ion packs of this size (1152 Wh) require safe transport and storage. The fireproof box is the industry-standard solution for charters, yachts and shipping operators.
Safe On-Board Storage
Keep the Elite stored in the fireproof box between dives. If anything goes wrong with the battery in transit or rest, the box contains the issue to a defined volume.
Designed for the Elite
Sized exactly for the SeaNXT Elite scooter and battery — the contents sit cleanly inside the box without forced packing or sliding around.

Fireproof Box vs. Carry Bag vs. Mounting Rack
The Elite accessory range covers different transport and storage scenarios:
| Option | Function | Best for |
|---|---|---|
| Fireproof Transport Box (this product) | Heat containment, lithium-ion safe storage and shipping | On-board storage, shipping, long-term storage |

| Mounting Rack | Fixed wall / shelf storage | Permanent yacht / garage storage between sessions |
Who is the Fireproof Box for?
The Elite Fireproof Transport Box is designed for SeaNXT Elite owners and operators who want maximum lithium-ion safety:
- Yacht and superyacht owners who store the Elite on board between dive sessions — fireproof containment is critical for closed-quarters storage
- Charter and dive-school operators who move scooters between locations and need the industry-standard transport box
- Owners shipping the Elite via air or sea freight — lithium-ion shipping regulations require certified containment
- Safety-conscious owners who keep the Elite at home and want fireproof storage as standard precaution
- Marine and aviation operators who must comply with IATA / IMDG dangerous-goods rules for lithium-ion transport
For non-storage short-distance carrying use the lighter Carry Bag alongside the fireproof box.
FAQ — Safety, Use & Compliance
What does the fireproof box protect against?
Thermal runaway of the lithium-ion battery. The aluminium body and treated EVA plates contain heat inside the box and prevent it from propagating to surrounding objects or compartments.
Which scooter does the box fit?
The box is sized exactly for the SeaNXT Elite scooter and its 48 V battery — not compatible with other scooter brands.
Why is fireproof storage important for lithium-ion batteries?
Lithium-ion packs of the size used in the Elite (1152 Wh) can release a large amount of energy in a thermal event. Containment is critical on yachts and in confined spaces where heat propagation could damage the vessel.
Should I always store the Elite in the fireproof box?
Yes — for on-board, long-term and shipping storage. The Carry Bag is fine for the few minutes between car and water; the fireproof box is the right answer for everything longer.
Is the box airline / shipping certified?
The box is designed to lithium-ion containment standards used by air and sea freight operators. Always check the latest IATA / IMDG rules with your shipper before transporting.
Does the box add a lot of weight?
Aluminium construction keeps the box manageable while delivering the required containment. With the 23 kg scooter and 8 kg battery inside the loaded box becomes a two-person carry.
Can the box be used at home?
Yes — for safety-conscious owners who want fireproof storage at home alongside on-board use, this is the recommended storage solution.
Is the box waterproof?
The box is engineered for fireproof containment, not waterproofing. Keep it stored in a dry yacht locker or garage; transport in a vehicle is fine in normal conditions.
What is the treated EVA insert for?
The EVA plates absorb heat during a thermal event — they’re the secondary layer that keeps the aluminium walls within safe temperatures.
Does the box come with the Elite scooter?
Yes — one fireproof transport box ships with the full SeaNXT Elite set. This listing covers spare or replacement boxes for multi-location owners and charter operations.
Can I also store the spare battery inside the box?
The primary use is the complete scooter + battery as a unit. For separate spare-battery storage, contact us for fireproof storage options sized to the battery alone.
How long can the Elite stay in the box?
Indefinitely — the fireproof box is designed for long-term storage. For best battery lifespan, keep the pack at 40–60 % charge during long storage periods and avoid extreme heat.
