Victron Energy Smart Battery Sense Voltage/Temperature Sensor

Smart Battery Sense is a wireless battery voltage and temperature sensor for Victron MPPT solar chargers. When installed, the voltage and temperature sensor will charge batteries better, improve charging efficiency and extend battery life.

Improves battery charging
By measuring the voltage at the battery bank terminals, you can avoid errors caused by voltage drop due to cable resistance and thus ensure the correct charging voltage.

For lead-acid batteries, battery temperature information is used to adjust the charging voltage: cold batteries require a higher charging voltage and warm batteries a lower charging voltage. For lithium batteries, battery temperature information is used to stop charging when they are too cold. Charging a lithium battery at or below freezing can permanently damage the cells.

Bluetooth
The connection between Smart Battery Sense and one or more solar chargers is wireless: It uses VE.Smart Network - a wireless technology based on Bluetooth Smart.
The transmitted data can be used simultaneously by one, two or more solar chargers connected to the same 12V, 24V or 48V battery bank. The Smart Network is configured using the VictronConnect app.

Clean, simple – smart
Installation is simple, quick and clean. Simply connect the two loops of the device to the battery terminals and attach the Smart Battery Sense device directly to the battery with the Velcro.
