AMEL 50 & Momentum M10: The Lazarette, the Ideal Storage Space for Your Electric Battery
When installing an electric propulsion system on board, one of the first questions that arises is where to store the battery. On the AMEL 50, the answer is found naturally in the stern lazarette: a storage space perfectly dimensioned to accommodate the MB-6 battery of the Momentum M10.
The AMEL 50 Lazarette: A Space Designed for the Momentum Battery
The stern lazarette of the AMEL 50 offers a generous volume, easily accessible from the cockpit. During our installation, we found that the MB-6 battery fits in remarkably naturally, without encroaching on the other storage areas on board.
Its low and centred position in the lazarette contributes to an excellent distribution of weight — a detail far from trivial on an offshore cruising sailboat like the AMEL 50. The battery is perfectly secured, with enough room to optimise cable routing and ensure good ventilation.

The MB-6 Battery: Compact, Lightweight and High Performance
The Momentum MB-6 battery is designed to meet the demands of everyday sailing. Here are its main features:
- Capacity: 6.4 kWh (approx. 5.5 kWh usable)
- Technology: Li-ion NMC, robust and durable
- Voltage: 72 V, a rare and efficient solution for a 10 kW motor
- Weight: approximately 30 to 37 kg depending on configuration
- Connectors: waterproof, suited for marine use
- Handling: portable by hand, ideal for easy boarding
With a manageable weight and compact dimensions, the MB-6 is designed to integrate discreetly into the storage spaces of modern boats, whether a cruising sailboat, a tender, or a workboat.

The Momentum M10: An Electric Motor That Adapts to All Boats
The Momentum M10 is a 10 kW electric outboard motor (approximately 20 hp), designed to be as versatile as it is powerful. It is suitable for:
- Fast tenders for cruising sailboats
- Open boats under 5,000 kg displacement
- Workboats and professional vessels
- Semi-rigid (RIB) used for leisure or professional purposes
Available in short (39 cm) or long (52 cm) shaft lengths, the M10 adapts to a wide variety of hull types and transoms. Its lightweight design (approximately 22-23 kg for the motor) and independent mounting system make handling on deck or on the stern platform easy.
Paired with the MB-6 battery perfectly housed in the AMEL 50’s lazarette, the combination forms a coherent, silent and zero-emission electric propulsion solution — ideal for owners wishing to modernise their tender or reduce their dependence on combustion engines.

Conclusion: The AMEL 50, A Sailboat Naturally Compatible with the Momentum M10
This installation once again confirms that the Momentum M10 is an electric propulsion solution designed for the real world of sailing. The AMEL 50’s lazarette, often underused, becomes a major asset for discreetly and efficiently integrating the electric battery on board.
