This device ensures that both batteries are optimally charged without affecting each other. ### Microprocessor-controlled operation Thanks to the advanced microprocessor, the BS400 automatically connects the batteries in parallel when one of the batteries reaches a voltage of 13.2V (for 12V systems) or 26.4V (for 24V systems). This indicates a charging status. The connection is broken when the voltage drops to 12.8V or 25.6V, indicating discharge. ### Advantages of the BS400 - **No voltage loss**: The BS400 minimizes voltage loss, so the output voltage of alternators or battery chargers does not need to be increased. - **Easy installation**: The existing circuit does not need to be modified, simplifying installation. - **Starter battery protection**: Prevents excessive discharge of the starter battery by prioritizing its charging. ### Technical specifications - **Input voltage**: Automatic detection of 12V or 24V - **Output voltage**: 13.2V or 26.4V - **Maximum current**: 100A - **Dimensions**: 46 x 46 x 80 mm - **Weight**: 110 g ### Applications The BS400 is ideal for use in: - **Motorhomes**: Ensures reliable power supply while traveling. - **Boats**: Keeps both the starter and service batteries in optimal condition. - **Caravans**: Provides an efficient energy management solution for mobile living spaces. ### Reliability and quality SAMLEX is known for its high-quality products. The BS400 is ISO 9001-2015 certified and undergoes strict quality controls to ensure reliability and durability. ### Summary With the SAMLEX battery isolator BS400, you are assured of an efficient and reliable solution for managing dual batteries in various vehicles. The combination of advanced technology and ease of use makes this product a valuable addition to your electrical system. ## Breadcrumbs - [Brands](https://www.auto-service.be/en/brands) - [SAMLEX](https://www.auto-service.be/en/brands/samlex) ## Related products -
