Victron Smart BatteryProtect 12/24V-220A deep discharge protection

SmartBatteryProtect 12/24V 220 A by Victron Battery Protection with Bluetooth

The BatteryProtect disconnects the battery from less important consumers before it is completely discharged (which would damage it) or before it no longer has enough energy to start the engine.

Bluetooth: Easy programming
By using Bluetooth to program the Smart BatteryProtect, all required on/off thresholds can be set.
Alternatively, one of nine preset on/off thresholds can be set using the programming pin (see manual).
If necessary, the Bluetooth function can be disabled.

The BatteryProtect automatically detects the system voltage.

The BatteryProtect can be set to switch 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 load breaker between a battery charger and a Li-ion battery. See the wiring diagram in the manual.

This is important in the case of lithium-ion batteries, especially after switching off 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 consumers from being damaged by overvoltage, the load is always switched off when the DC voltage exceeds the value of 16 V or 32 V.

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

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