Victron Energy BatteryProtect BP-100 100AMP Battery Management System for 6-35 VDC Systems

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 high-performance battery management device designed to safeguard your battery bank from damage caused by over-discharge or over-voltage conditions. With a current capacity of 100 amps and a voltage range of 6 to 35 volts DC, this unit is suitable for a wide variety of automotive, marine, and renewable energy applications. Its intelligent design ensures that critical loads are disconnected before the battery reaches a dangerously low state, extending battery life and maintaining system reliability. The device automatically detects system voltage, providing seamless operation across 12V and 24V systems, and features user-friendly programming with a seven-segment display that indicates the current setting. This allows users to customize cutoff and reconnect voltages to match their specific battery chemistry and usage needs, including a dedicated mode for Li-ion batteries controlled via VE.Bus BMS. The BatteryProtect’s ultra-low current consumption is especially beneficial for lithium-ion batteries, reducing parasitic drain during shutdown periods. Over-voltage protection prevents damage to sensitive electronics by disconnecting loads when voltage exceeds 16V or 32V, depending on the system configuration. Its ignition-proof design employs MOSFET switches instead of relays, eliminating sparks and enhancing safety. The device includes a delayed alarm output that activates if the battery voltage remains below the set threshold for more than 12 seconds, preventing false alarms during transient voltage dips. Additionally, load disconnection occurs 90 seconds after alarm activation, with reconnection occurring 30 seconds after the voltage recovers, ensuring system stability during engine startup or other transient events. Built with reliability and safety in mind, the Victron Energy BatteryProtect BP-100 is an essential component for maintaining optimal battery health and preventing damage to your electrical system.
