BatteryProtect 12/24V 100A by Victron Battery Protection

The BatteryProtect disconnects the battery from non-essential loads before it is completely discharged (which would damage it) or before it no longer has enough power to start the engine.

The BatteryProtect automatically detects the system voltage.

The BatteryProtect can be set to turn on or off at several different voltages. The seven-segment display then indicates which setting has been selected.

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

This is important for lithium-ion batteries, especially after shutdown due to a low voltage level. Please also refer to our data sheet on lithium-ion batteries and the VE.Bus BMS manual for further information.

To prevent sensitive loads from being damaged by overvoltage, the load is always disconnected when the DC voltage exceeds 16V or 32V.

No relays, but MOSFET switches, and therefore no sparks. Output for delayed alarm The alarm output is activated when the battery voltage drops below the preset shutdown value for more than 12 seconds. Starting the engine therefore does not activate the alarm. The alarm output is a short-circuit protected open collector output connected to the negative (minus) rail. Max. current 50 mA. The alarm output is normally used to activate an audible signal, an LED or a relay.

The load is disconnected 90 seconds after the alarm is activated. If the battery voltage rises again to the connect threshold within this 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 exceeded the preset reconnect voltage value.
