Victron Energy Smart Battery Protect BP-100

The Smart BatteryProtect 100A (12/24V) disconnects the battery from non-essential loads before it is completely discharged (which can damage the battery) or before it has insufficient power to start the engine.

When using Bluetooth to program this Smart BatteryProtect, all required activation/deactivation levels can be set. The VictronConnect app is required for this. Alternatively, one of the nine predefined activation/deactivation levels can be set with the programming pin (see manual). The Bluetooth function can be turned off if necessary.

The Smart BatteryProtect 100A protects the battery against excessive discharge and can be used as an on/off switch system. For this 100A model, the maximum continuous current is 100A and the peak current (for 30 seconds) is 650A with an operating voltage range of 6 – 35V. The battery is disconnected from non-essential loads before the battery is fully discharged (which would damage the battery) or before there is insufficient power left to start the engine. The input/output can be used as an on/off switch system.

Automatic detection 12/24V
The Smart BatteryProtect automatically detects the system voltage only once.

Bluetooth: easy programming
When using Bluetooth to program the Smart BatteryProtect, all required activation/deactivation levels can be set. Alternatively, one of nine predefined activation/deactivation levels can be set with the programming pin (see manual). If necessary, Bluetooth can be turned off.

A special setting for lithium-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.

Super low power consumption
This is important in the case of lithium-ion batteries, especially after a low voltage shutdown. See our Li-ion battery datasheet and VE.Bus BMS manual for more information.

Overvoltage protection
To prevent damage to sensitive loads due to overvoltage, the load is disconnected as soon as the DC voltage exceeds 16V and 32V respectively.

Protected against ignition
No relays, but MOSFET switches and therefore no sparks.

Delayed alarm output
The alarm output is activated if the battery voltage falls below the preset disconnect level for more than 12 seconds. Therefore, starting the engine does not activate the alarm. The alarm output is an open collector short circuit proof output connected to the negative (minus) rail, max. current 50mA. The alarm output is generally used to activate the buzzer, an LED or relay.

Delayed load disconnection and delayed reconnection
The load is disconnected 90 seconds after the battery voltage drops below the preset level. If the battery voltage rises back to the clutch threshold within this time frame (e.g. after the engine is started), the load will not be disconnected. The load will be reconnected 30 seconds after the battery voltage rises above the preset reconnect voltage.
