If you charge or store lithium-ion batteries on a yacht or commercial vessel, uncertified “fireproof” boxes aren’t enough.
LiVault delivers DMT (TÜV NORD GROUP) tested containment and Lloyd’s Register-appraised marine systems, integrated toxic-gas filtration, blast/overpressure relief, and active monitoring, purpose-built for MGN 681style requirements.
Detect → Contain → Cool → Filter → Alert
(Home – Leisure – Commercial)
Use cases: e-bikes, e-scooters, power tools, damaged batteries—at home, in workshops, in vans, or in technical spaces.
(Marine: yachts, day boats)
Use cases: e-foils, drone batteries, water toy battery packs
(Superyacht & Commercial Marine)
Use cases: e-foils, Seabobs and larger batteries. Professional installation & service worldwide; periodic onboard maintenance available.
Still common but risky on vessels:
LiVault’s marine guidance details these pitfalls and why only certified, purpose-built boxes should be used onboard.
Li-ion fires produce toxic by-products and explosive pressure waves; containment + filtration + monitoring are the controls that align with marine guidance.
| Solution | Gas Capture | Blast/Overpressure | Active Monitoring | Marine Rating | Independent Validation |
|---|---|---|---|---|---|
| LiVault RACLAN / RAMBSS | Toxic-gas filtration | Engineered overpressure relief | Temp + smoke/gas with auto cooling | Yes (watertight modules, yacht installations) | DMT–TÜV Nord testing; RAMBSS LR DAD |
| Fire blankets / bags | ❌ | ❌ | ❌ | Not specific | None stated |
| Generic flammable-liquid cabinet | ❌ (not for Li-ion gases) | ❌ | ❌ | Not marine | None stated |
| Unprotected Charging | ❌ | ❌ | ❌ | ❌ | ❌ |
LiVault systems map to the control measures outlined in MGN 681 (M), often exceeding them in areas like containment, monitoring, and exhaust.
Marine insurers and clubs are aligning with MGN 681 principles. RAMBSS has been validated under Lloyd’s protocols, with the D.A.D. stating: “A verified container as part of an arrangement to MCA MGN681 (M)”.
Recent Underwriters Clause: “ any Lithium Battery […] shall only be charged in a Container, or within a space meeting the requirements of Section 14.1 of the REG Yacht Code or on open deck where the risk of fire and accumulation of toxic gas is minimized”
Lower operational risk; align with classification and insurance expectations. Fit-for-purpose modules that adapt to tender garages and tech rooms.
Charge inside the box; no risky battery shuffling. Local/remote alarms, routine service support when required.
Independently tested containment and filtration; Lloyd’s DAD appraisal for RAMBSS; easier risk acceptance and pricing.
LiVault RACLAN systems have been independently tested (DMT, TÜV NORD GROUP) according to the test program for storage means for lithium-ion batteries (TÜV NORD CERT test program no.: M02/22). RAMBSS carries a Lloyd’s Register Design Appraisal (DAD) for Storage and charging Li-Ion batteries on board of large Yachts. It is cited as: A verified container as part of an arrangement compliant to MGN 681 (M), document number TSO-24-013730-F01-DA.
No. EN 14470 – Fire safety storage cabinets – Part 1: Safety storage cabinets for flammable-liquids are designed to prevent existing fires outside the cabinet from igniting the flammable contents. They are for land use and don’t cover marine dynamics or lithium-ion thermal-runaway gases. At sea, a marine-approved lithium battery system with sealed containment, overpressure relief, toxic-gas (incl. HF) filtration, and forced extraction to open air should be used.
Toxic gases are forced through a flow path of multi-stage media to treat gases such as Hydrogen and Hydrogen Floride (HF). Testing showed a maximum HF Concentration < 95 ppm and an HF Concentration in 15 min Interval < 34 ppm.
Yes. The essence of our systems is active monitoring of the batteries as they charge. If the system detects a rise in temperature it immediately cuts the power to charging. If the temperature continues to rise it starts to spray the Trident cooling agent to slow thermal runaway. On all systems a loud audible and visual alarm will sound. In RAMBSS systems the connection to the AMCS will generate an alarm in the vessel’s systems.
Sensors trigger alarms, cut power, and deploy TRIDENT agent to slow propagation; exhaust is routed through filters to neutralize toxic and explosive gases before release.
Yes. LiVault systems are designed for internal, monitored charging with integrated sockets and safety interlocks.
Yes. Choose RACLAN for smaller packs and E-Foil batteries and RAMBSS modules for larger water toys and Seabobs.
MGN 681 calls for controls around charging, stowage, and dedicated spaces; LiVault’s unique containment, monitoring, and exhaust features address those elements and exceed them in many areas.
