RAMBSS – Maritime Battery Safety System
Advanced safety for the charging and storage of watertoy batteries on board
Delignit Technologies Italia is an authorized distributor of Raclan Maritime Battery Safety Systems (RAMBSS), a modular solution designed for the safe charging and storage of lithium-ion batteries used in watertoys on board yachts.
The system is designed to safely accommodate batteries, chargers and devices such as Seabobs with permanently integrated batteries, helping to reduce the risks associated with lithium-ion battery charging and storage on board.
RAMBSS combines detection, temperature control, gas management, cooling and containment in a single modular system specifically designed for the marine environment.
Dimensions
| Module | External dimensions (mm) | Internal dimensions (mm) |
|---|---|---|
| Module 500 | 700 x 600 x 500 | 520 x 550 x 280 |
| Module 750 | 700 x 600 x 750 | 520 x 520 x 532 |
| Module 1500 | 700 x 600 x 1520 | 520 x 520 x 1300 |

Certifications and Approvals
RAMBSS modules are the first and only systems to receive Type Approval by Lloyd’s Register in accordance with the requirements of the MCA MGN 681 Amendment 1 guideline.
The fire suppression insert is certified in accordance with SOLAS and IMO requirements.
Key Features
- Capacity: designed for lithium-ion watertoy batteries up to 5.25 kWh.
- Advanced cooling: high-performance cooling system using an environmentally friendly fluid. Each module can be flooded individually through a permanent water connection, helping to prevent re-ignition in the event of thermal runaway.
- Gas filtration: multi-stage filtration system for managing gases generated during an incident, with the ability to absorb hydrogen fluoride (HF), hydrogen and volatile organic compounds (VOCs).
- Monitoring and control: managed through a PLC and touchscreen interface.
- Safety sensors: equipped with two thermal sensors, one smoke sensor and one gas sensor. Safety components are designed with redundancy.
- On-board integration: can be connected to the yacht’s AMSC system, providing visual and audible alarms.
- Construction: high-strength composite structure designed to help absorb explosion and pressure effects.
- Modular installation: modules can be stacked or mounted to the floor, wall or ceiling, providing flexibility for installation on board.
- Emergency power supply: includes an emergency power supply providing up to three days of autonomy.
- Post-incident management: after an incident, the cooling fluid can be pumped out of the module without opening it.

Designed for the Yacht Environment
RAMBSS addresses a growing on-board safety requirement: the safe management of lithium-ion batteries used for Seabobs, electric jet skis, e-foils, tenders and other watertoys.
The modular configuration allows the system to be adapted to the specific requirements of each yacht, optimizing the available space while enabling integration with on-board safety systems.
With its extensive experience in the marine sector, Delignit, under the Bellotti brand, offers RAMBSS to shipyards, yacht builders, interior contractors, yacht managers and yacht owners looking for a dedicated solution for the safe management of watertoy batteries on board.
