Superior safety
Sodium-ion chemistry emphasizes stability and thermal-runaway resistance for calmer onboard energy-system operation.
Advanced battery systems with high CCA ratings, Bluetooth monitoring, NMEA2000 readiness and IP67 protection for vessels that need safe energy, reliable starting and long service life at sea.
Marine environments need a battery that safely starts the engine, supports electronics and handles moisture, vibration, cold and frequent charging cycles.
SulMate highlights safety, cold-start performance, more sustainable raw materials and long cycle life. For marine use, that means fewer compromises between a starting battery and service loads.
Sodium-ion chemistry emphasizes stability and thermal-runaway resistance for calmer onboard energy-system operation.
High CCA and reliable starting power help with engines, changing conditions and seasonal vessel use.
Sodium is naturally abundant, making sodium-ion attractive for a more sustainable and resilient supply chain.
4000+ cycles provide a strong base for vessels that frequently charge and discharge the service bank during the season.
The construction is suited to the marine environment: vibration, water, IP67 protection and everyday life on the water.
Bluetooth monitoring and NMEA2000 readiness make supervision, service checks and integration into a modern vessel system easier.
Six models cover 12V and 24V configurations, from compact starting choices to larger capacity for dual-purpose and stronger onboard installations.

We process inquiries fastest when they include real vessel, engine, current battery, charging and intended-use data. The next step is a review of model, quantity, compatibility and quote.
Choose the goal: starting, service bank or dual purpose
Send vessel model, length and engine details
We review charging, installation position and battery quantity
We send a technical recommendation and individual quote
SulMate models differ in CCA rating, energy, dimensions and weight. The recommendation is therefore matched to the real engine, install space, charging setup and onboard loads.
The SulMate range is intended for Start and Dual Purpose use. In practice, the choice is confirmed against engine, CCA need, loads and charging setup.
The quote depends on the model, quantity, compatible charging, delivery and installation scope. After reviewing the vessel details, we confirm the current price and recommended configuration.
