Description
Smart Battery Sensor
Monitor your battery voltage in real time, prevent deep discharge and extend their lifespan. Compatible with 12V and 24V — 2 independent banks.
Sense4Boat Battery Sensor
The Sense4Boat battery sensor continuously monitors the voltage of your on-board batteries. Every voltage variation is transmitted to the Sense4Boat control center and compared to the thresholds you have defined.
Connect the sensor to two independent battery banks using the 3-meter cables provided with protective fuses. Receive an alert as soon as a low, critical voltage, or a charging anomaly is detected.
How the Sense4Boat system monitors your batteries
From the sensor connected to the terminals to the alert on your phone — continuous and intervention-free monitoring
Everything you need to protect your batteries
A standalone sensor that monitors, alerts, and helps you extend the lifespan of your marine batteries
Sulfation: the silent enemy of your batteries
Understand this phenomenon to better protect your investment
What is sulfation?
Marine batteries are expensive and often last only a few seasons. The main cause of premature death is poor maintenance. The golden rule is simple: a battery must always be stored in a charged state.
When a battery is stored partially discharged, a chemical process of lead sulfate crystal deposition occurs on the plates. This phenomenon — sulfation — is responsible for the irreversible reduction of capacity. The longer the battery remains discharged, the more crystals deposit and gradually reduce the available capacity.
The Sense4Boat battery sensor alerts you as soon as the voltage drops, allowing you to act before sulfation sets in. Manufacturers announce a lifespan of 7 to 10 years — with proper monitoring, you can achieve it.
Be alerted immediately, everywhere
As soon as a voltage anomaly is detected, you and your emergency contacts are notified simultaneously
Operational in less than 15 minutes
No complex wiring, no central unit — simply connect the cables to your battery terminals
