Smart BP-65 12/24V battery protection

Smart BatteryProtect protects the battery from excessive discharge (which could damage the battery) and can be used as an on/off switch.

Automatic 12/24V setting
BatteryProtect automatically detects the voltage in the system.

Integrated Bluetooth = very easy programming
Thanks to the integrated Bluetooth programming function of the Smart BatteryProtect, the desired voltage levels for connecting/disconnecting the load can be easily set. Settings can be made via smartphone, tablet or PC using the VictronConnect app. Alternatively, one of nine preset connection/disconnection levels can be set using the programming pin (see manual). Bluetooth can be switched off if required.

VictronConnect app
Download the app for free under the name VictronConnect app in the App Store or Google Play.

Special settings for Li-ion batteries
In this mode, Smart BatteryProtect can be controlled via the VE.Bus BMS.
Note: Smart BatteryProtect can also be used as a charge disconnect between the battery charger and the Li-ion battery. See the wiring diagram in the manual.

Very low power consumption
Low power consumption is very important for Li-ion batteries, especially after low voltage shutdown.

Surge protection
In case of overvoltage resulting in possible damage to sensitive devices, the devices are disconnected if the DC voltage exceeds 16 V or 32 V.

Spark-proof
Does not work with relay elements but with MOSFET transistor switches, no sparking occurs.

Delayed alarm output
The alarm output is activated if the battery voltage drops below the set value for more than 12 seconds. Starting the engine, therefore, does not activate the alarm. The alarm output is an open collector output on the negative bus, max. current 500 mA. The alarm output is typically connected to a buzzer or to a traffic light.

Delayed Load Disconnect
The load is disconnected 90 seconds after the alarm has been triggered. If during this time the battery voltage rises to the "connection threshold" level (e.g. during engine start), the load will not be disconnected. The load will reconnect 30 seconds after the battery voltage rises to more than the preset reconnect voltage.

BatteryProtect is unidirectional i.e. current can only pass from the "in" input to the "out" output. Reverse current flowing from the "out" output to the "in" input is not allowed and will damage the device
