The Momentum Electric Marine MB-6 delivers high-performance, marine-grade power in a lightweight, compact package. With advanced NMC cell chemistry and a rare 72‑volt architecture, it pairs seamlessly with the M10 outboard to give longer range, cooler operation, and a smaller payload than typical 48‑volt alternatives.
Key features
-
High capacity: 6.4 kWh total; 5.5 kWh usable for extended range and longer run times.
-
72‑volt advantage: Higher-voltage design yields better efficiency and lower heat compared with common 48‑volt systems.
-
NMC chemistry: Nickel Manganese Cobalt cells for high energy density and robust thermal stability.
-
Best-in-class weight-to-power: More capacity per pound to keep boats lighter and more responsive.
-
Durable life: Designed for more than 1,500 cycles with about 80 percent capacity retention for years of dependable use.
-
Smart safety: Built-in intelligence removes the 72V supply if the M10 or magnetic kill switch is not present, preventing shorts in saltwater environments.
-
Marine ready: Compact, modular form factor with IP-rated waterproof connectors engineered for harsh conditions.
Compact, efficient, and purpose-built for electric boating — the MB-6 brings professional-level performance without compromising on durability or safety.
