B48 is the heart of the Searine system. Designed specifically for sailing yachts, the 48V lithium battery system delivers reliable power, flexible installation and scalable capacity to match your yacht and the way you sail.

Range depends on several factors, including the number of B48 battery modules installed, your yacht’s size and displacement, wind conditions, current and your speed through the water.
One of the biggest advantages of electric propulsion is its flexibility. In light winds, you can combine sail and motor to maintain a higher average speed in near silence—without diesel fumes, vibration or engine noise.

The example above shows a 38-foot Hercules equipped with ten B48 battery modules, achieving a real-world range of more than 80 nautical miles under electric propulsion alone.
In practice, many sailors combine sail and electric propulsion. As the sails provide part of the driving force, the motor consumes less energy, allowing the yacht to travel considerably farther on the same battery capacity.
The B48 battery system is designed to fit your yacht—not the other way around. Batteries can be distributed throughout the yacht to optimize weight distribution, maximize available space and tailor battery capacity to your sailing needs. Whether you’re heading out for a weekend cruise or a long-distance passage, B48 delivers a solution built specifically for your boat.
B48 is built around an intelligent modular architecture. Each battery module operates independently, allowing the system to automatically recognize, balance and manage every connected module. This enables scalable capacity, faster charging, improved redundancy and a level of flexibility not found in conventional marine battery systems.

Safety is built into every B48 module. In addition to continuously monitoring voltage, current and temperature, the system also monitors humidity and gases inside the battery. This allows potential issues to be detected at an early stage, providing an extra layer of safety and peace of mind on the water.
