Why We Recommend NMC for Outboards

For propulsion applications, NMC batteries provide the best ratio of power, weight, and efficiency. They deliver high discharge currents and maintain strong performance even in cold weather.

Up to 40 % higher energy density than LFP
Excellent power retention at low temperatures
Lightweight design for improved planing and range
Fast charge and discharge capability

Customization Options

Connectors: Anderson, Amphenol, or custom marine HVIL
Enclosures: IP67 aluminum housings, compact or elongated formats
Parallel connection for extended range
Optional Bluetooth monitoring or integrated display
