The Momentum MB-6 6.4kW Li-ion Battery powers your marine adventures with a massive 6.4 kWh capacity and cutting-edge NMC cell technology. Designed to pair perfectly with the Momentum M10 and M6 outboards, it provides the necessary juice for sustained speed and useful range.

Unlike standard 48-volt systems, the MB-6 utilizes a rare 72-volt architecture. This delivers superior efficiency, cooler operation, and eco-friendly performance that easily outclasses competitors. Weighing just over 80 lbs, this compact powerhouse is portable and built to survive the harshest marine conditions.

Key Features & Safety

Advanced Safety (BMS): The proprietary Battery Management System features intelligent safety logic. It instantly cuts the 72V supply if the motor or magnetic kill switch is disconnected, preventing dangerous electrical shorts in saltwater environments. It also includes over-charge protection and fire-resistant cells.
Compact & Portable: Designed with a CNC aluminum handle and a shock-resistant casing, it is easy to transport. It is specifically sized to fit into standard fuel lockers, keeping your deck clear and the battery out of the elements.
Marine Ready: Features IP-rated waterproof connectors and an optimal seal for reliable operation in harsh, wet sea conditions.
Plug-and-Play Setup: A flexible, waterproof CAN-Bus cable ensures a simple, quick, and secure connection to your outboard without the need for complex wiring.

Why NMC (Nickel Manganese Cobalt) Technology?

The MB-6 utilizes premium NMC cells, which offer significant advantages for demanding marine applications:

High Energy Density: Stores more energy in a smaller footprint, saving valuable space and weight on your boat while maximizing your cruising range.
Long Cycle Life: Highly durable chemistry capable of over 1,500 charge-discharge cycles while still maintaining 80% of its original capacity, greatly reducing long-term replacement costs.
Improved Safety & Thermal Stability: The highly stable chemical structure drastically reduces the risk of thermal runaway (overheating or fires) and performs reliably across a wide range of temperatures.
Balanced Performance & Fast Charging: Strikes the perfect balance between high-power output (for instant acceleration) and long-term energy storage, while also supporting rapid recharge times so you can get back on the water faster.
