Victron Smart BatteryProtect 12/24V-65A

Protects the battery against excessive discharge and can be used as a system on/off switch

The Smart BatteryProtect disconnects the battery from non-essential loads before it is completely discharged (which would damage the battery) or before it has insufficient power left to crank the engine. The on/off input can be used as a system on/off switch.

Key Features:

12/24V auto ranging

• The Smart BatteryProtect automatically detects system voltage one time only.

Bluetooth: programming made easy

• Using Bluetooth, any required engage/disengage levels can be set.
• Alternatively, one of nine predefined engage/disengage levels can be set with the programming pin (see manual).
• If required, Bluetooth can be disabled.

A special setting for Li-ion batteries

• In this mode, the BatteryProtect can be controlled by the VE.Bus BMS.
• Note: The BatteryProtect can also be used as a charge interrupter between a battery charger and a Li-ion battery. See connection diagram in the manual.

Ultra-low current consumption

• Especially important in case of Li-ion batteries, particularly after low voltage shutdown.
• Refer to the Li-ion battery datasheet and the VE.Bus BMS manual for more information.

Over voltage protection

• To prevent damage to sensitive loads due to over voltage, the load is disconnected whenever the DC voltage exceeds 16.3V or 32.6V.

Ignition proof

• No relays but MOSFET switches, ensuring no sparks.

Delayed alarm output

• The alarm output is activated if the battery voltage drops below the preset disconnect level for more than 12 seconds.
• Starting the engine will not activate the alarm.
• The alarm output is a short circuit proof open collector output to the negative (minus) rail, max. current 50 mA.
• Typically used to activate a buzzer, LED, or relay.

Delayed load disconnect and delayed reconnect

• The load will be disconnected 90 seconds after the battery voltage drops below the preset level.
• If the battery voltage increases again to the connect threshold within this time period (e.g., after the engine has been started), the load will not be disconnected.
• The load will be reconnected 30 seconds after the battery voltage has increased to more than the preset reconnect voltage.
