Victron Smart BatteryProtect 12/24V 65A deep discharge protection

SmartBatteryProtect 12/24V 65A from 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
Set the required on/off thresholds.
Alternatively, one of nine preset on/off thresholds can be set using the programming pin
set (see manual).
If necessary, the Bluetooth function can be switched off.

The BatteryProtect detects the system voltage automatically.

The BatteryProtect can be set to switch on or off at several different voltages. The seven-segment display then shows 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 case of lithium-ion batteries, especially after shutdown due to low voltage level. Please refer to our lithium-ion battery datasheet and the VE.Bus BMS manual for more information.

To prevent sensitive consumers from being damaged by overvoltage, the load is always switched off 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 shutdown level for more than 12 seconds. Therefore, switching on the engine 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 acoustic signal, LED or relay.

The load will be disconnected 90 seconds after the alarm is activated. If the battery voltage rises to the reconnection threshold again within this time (for example, 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 reconnection voltage.
