The Smart BatteryProtect protects the battery by disconnecting non-essential loads before it is completely discharged (which would damage it) or before there is insufficient power left to start the engine.
When using Bluetooth to program the Smart BatteryProtect, you can set any desired switch-on/switch-off level. Alternatively, you can set one of the nine preset switch-on/switch-off levels using the programming pin (see instruction manual).
If required, Bluetooth can be switched off.
The BatteryProtect function is not designed for reverse currents from charge sources.
Protects the battery from deep discharge and can be used as an on/off switch for a

12/24 V Automatic sensing
The Smart BatteryProtect automatically senses the system voltage, and only once.
Bluetooth: very easy programming
When using Bluetooth to program the Smart BatteryProtect, you can set any desired switch-on/switch-off level.
Alternatively, you can set one of the nine preset switch-on/switch-off levels using the programming pin (see instruction manual).
If required, Bluetooth can be switched off.
Special configuration 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 switch between a battery charger and a lithium-ion battery. See the connection diagram in the instruction manual.
Extremely low power consumption
This is an important feature for lithium-ion batteries, especially after a low-voltage shutdown.
Please consult our datasheet on lithium-ion batteries and the VE.Bus BMS manual for more information.
Overvoltage protection
To prevent damage to loads that are sensitive to overvoltage, the load is disconnected if the DC voltage exceeds 16.3 V and 32.6 V respectively.
Burnout protection
No relays, but MOSFET transistors, and therefore no sparks.
Delayed alarm output
The alarm output is activated if the battery voltage drops below the preset disconnect level for more than 12 seconds. Engine start-up will therefore not trigger the alarm. The alarm output is a short-circuit protected, open collector output that is connected to the rail (negative), maximum current 50 mA. The alarm output is typically used to activate a buzzer, LED or relay.
Load disconnect and reconnect delay
The load will be disconnected 90 seconds after the battery voltage drops below the preset level. If the battery voltage rises again to the connect threshold during this period (when the engine has started, for example), the load will not disconnect.
The load will be reconnected 30 seconds after the battery voltage has exceeded the preset load reconnect voltage for 30 seconds.
