Victron BatteryProtect 12/24V-220A

BatteryProtect 12/24V 220A from Victron battery protection

The BatteryProtect disconnects the battery from less important consumers before it is completely discharged (which would be damaged) or before it no longer has sufficient energy 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 connection diagram in the manual.

This is important in the case of lithium-ion batteries, especially after shutdown due to low voltage levels. Please also refer to our data sheet on lithium-ion batteries and the VE.Bus BMS manual for further Information.

To prevent sensitive consumers from being damaged by an overvoltage, the load is always switched off when when the DC voltage exceeds 16 V or 32 V.

No relays but MOSFET switches and therefore no sparking. Delayed alarm output The alarm output is activated when the battery voltage falls below the preset value for more than 12 seconds to shut down. Therefore, switching on the motor does not activate the alarm. The alarm output is a Short-circuit protected open collector output connected to the negative (minus) rail. Maximum current 50 mA. The alarm output is typically used to activate an audible signal, an LED or a relay.

The load will be switched off 90 seconds after the alarm is activated. If the battery voltage rises within this period (for example, after the engine has been started) again up to the threshold for connection, the load will not switched off. The load is reconnected 30 seconds after the battery voltage reaches the specified voltage value exceeded, reconnected.
