Battery Check harnesses the power of Bluetooth technology to provide you with real-time voltage information of your 12 Volt batteries directly on your smartphone or tablet, ensuring control and comfort at your fingertips. With the Seymo App, exclusively available for Android users, you can effortlessly manage up to four groups of batteries. This app allows you to monitor the voltage of each battery group conveniently from your mobile device.

Stay ahead of potential issues with the low battery alarm feature, which helps prevent deep and irrecoverable discharges. The app also provides a discharge percentage based on the battery voltage, giving you a clear picture of your battery's health:

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

The "OFF ALARM DISCONNECTED" feature ensures you're alerted when necessary. Additionally, the app includes voltage compensation for cable voltage drop to maintain accurate readings. For easy identification, you can rename each group of batteries, such as "engine battery" or "stern batteries," allowing for quick and efficient management.

The setup is straightforward, requiring only a negative wire and a positive cable for each group of batteries you want to control, up to a maximum of four groups.
