Victron Energy BatteryProtect BP-100 100AMP DC Battery Disconnect with Over Voltage and Low Current Protection

BatteryProtect BP-100 - 100AMP - 6-35 VDC

Features:

• The 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.
• 12/24V auto ranging The BatteryProtect automatically detects system voltage
• Programming made easy The BatteryProtect can be set to engage / disengage at several different voltages. The seven segment display will indicate which setting has been chosen.
• 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 in between a battery charger and a Li-ion battery. See connection diagram in the manual.
• Ultra low current consumption This is important in case of Li-ion batteries, especially after low voltage shutdown. Please see our 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 16V respectively 32V.
• Ignition proof No relays but MOSFET switches, and therefore no sparks.
• Delayed alarm output The alarm output is activated if the battery voltage drops below the preset disconnect level during more than 12 seconds. Starting the engine will therefore not activate the alarm. The alarm output is a short circuit proof open collector output to the negative (minus) rail, max. current 50 mA. The alarm output is typically used to activate a buzzer, LED or relay. Delayed load disconnect and delayed reconnect The load will be disconnected 90 seconds after the alarm has been activated. If the battery voltage increases again to the connect threshold within this time period (after the engine has been started for example), 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.

The Victron Energy BatteryProtect BP-100 is a reliable 100AMP battery management device designed for 6-35 VDC systems, ensuring optimal battery lifespan and safety. This unit automatically disconnects non-essential loads before the battery is fully discharged, preventing damage caused by deep discharge and ensuring the engine retains enough power to start. Its auto-ranging capability detects whether the system voltage is 12 or 24 volts, simplifying installation and operation. The intuitive seven-segment display allows for easy programming of disconnect and reconnect voltages, enabling customized settings to suit various battery types and system requirements. An important feature is the dedicated mode for Li-ion batteries, which can be controlled via VE.Bus BMS, and it can also serve as a charge interrupter between a charger and Li-ion batteries, providing added flexibility for energy systems.

Features:

• Disconnects non-essential loads before battery is fully discharged to prevent damage and ensure engine start capability

• Automatically detects system voltage between 12V and 24V for seamless configuration

• Easy programming with a seven-segment display showing current setting, allowing adjustments at different voltages

• Special mode for Li-ion batteries, compatible with VE.Bus BMS, and useful as a charge interrupter

• Ultra-low current consumption ideal for Li-ion batteries, especially after low voltage shutdown

• Over voltage protection disconnects loads if voltage exceeds 16V or 32V, protecting sensitive electronics

• Ignition proof design with MOSFET switches eliminates sparks and enhances safety

• Delayed alarm output activates if voltage remains low for over 12 seconds, preventing false alarms during engine start

• Delayed load disconnect occurs 90 seconds after alarm activation, with reconnection 30 seconds after voltage recovers to preset levels
