Kaptein NMC Series

Modular battery storage solutions for maritime challenges.

The Kaptein NMC Series sets new standards in maritime energy storage – combining ultra-lightweight design, high energy density, and proven reliability in the harshest marine environments. All modules are vibration-resistant, IP67-certified, and mountable in any orientation.

Whether it’s a retrofit or a new build, whether weight, space or budget are the driving factors – with Navigator, Compass, and Compass Core, the Kaptein Series offers the right solution for every vessel and every project goal.

Navigator
The Navigator combines ultra-lightweight design with outstanding energy density. Its vibration-resistant construction, seawater-compatible liquid cooling, and continuous 4C discharge rate make it the ideal solution for high-performance maritime applications – even under the toughest conditions.
Compass
The Compass brings the powerful DNA of the Navigator into an even lighter, more compact format. Available in two variants – Compass and Compass Core – it is designed for retrofits, tight engine rooms, and applications where weight, space, and efficiency are critical.
