Take control of up to 4 batteries or groups with the innovative Battery Check system. Using Bluetooth technology, you can monitor the voltage of your 12 Volt batteries directly on your smartphone or tablet, offering unparalleled convenience and comfort. Specifically designed for Android users, the Seymo App allows you to manage up to 4 groups of batteries, ensuring you stay on top of their performance at all times.

With Battery Check, you can easily view the voltage of each battery group on your mobile device. The system also features a low battery alarm, designed to prevent deep and potentially irrecoverable discharges, safeguarding your batteries' lifespan. Furthermore, you can monitor the discharge percentage based on the battery voltage, which provides clear indicators of your battery's status:

• 12.50V - 75%
• 12.20V - 50%
• 12.00V - 25%

The system also includes an OFF ALARM DISCONNECTED feature for added control. To ensure accurate readings, Battery Check incorporates voltage compensation to account for cable voltage drop. For easier identification and management, you can rename each group of batteries within the app—for instance, labeling them as "engine battery," "stern batteries," and so forth.

Installation is straightforward, requiring only a negative wire and a positive cable for each group of batteries, allowing you to control up to 4 groups efficiently.
