The Smart BatteryProtect 12/24V 65A disconnects the battery from non-essential loads before it is completely discharged (which would damage the battery) or before it has insufficient power left to crank the engine.When using Bluetooth to program the Smart BatteryProtect any required engage/disengage levels can be set.Alternatively, one of nine predefined engage/disengage levels can be set with the programming pin.If required, Bluetooth can be disabled.The Smart BatteryProtect 12/24V 65A is a uni-directional device. It can only deal with current in one direction, so either current to a load, or current from a charger, but not both currents at the same time. In addition to this, current only can only flow from the IN terminal to the OUT terminal. In case of use with a load, the battery connects to the IN terminal, and in case of use with a charger, the charger connects to the IN terminal. Features of the Battery Protect 12/24V 65AProtects the battery against excessive discharge and can be used as a system on/off switchThe Smart BatteryProtect disconnects the battery from non-essential loads before it is completely discharged (which would damage the battery) or before it has insufficient power left to crank the engine.The on/off input can be used as a system on/off switch. 12/24V auto rangingThe Smart BatteryProtect 12/24V 65A automatically detects system voltage one time only. Bluetooth: programming made easyWhen using Bluetooth to program the Smart BatteryProtect any required engage/disengage levels can be set.Alternatively, one of nine predefined engage/disengage levels can be set with the programming pin.If required, Bluetooth can be disabled. Over voltage protectionTo prevent damage to sensitive loads due to over voltage, the load is disconnected whenever the DC voltage exceeds 16.3V respectively 32.6V. Ignition proofNo relays but MOSFET switches, and therefore no sparks. Delayed alarm outputThe alarm output is activated if the battery voltage drops below the preset disconnect level during more than 12 seconds.Starting the engine will therefore not activate the alarm. The alarm output is a short circuit proof open collector output to the negative (minus) rail, max. current 50 mA. The alarm output is typically used to activate a buzzer, LED or relay. A special setting for Li-ion batteriesIn this mode the Smart BatteryProtect 12/24V 65A can be controlled by the VE.Bus BMS. Ultra-low current consumptionThis is important in case of Li-ion batteries, especially after low voltage shutdown. Delayed load disconnect and delayed reconnectThe load will be disconnected 90 seconds after the battery voltage drops below the preset level. If the battery voltage increases again to the connect threshold within this time period (after the engine has been started for example), the load will not be disconnected.The load will be reconnected 30 seconds after the battery voltage has increased to more than the preset reconnect voltage. Monitor, operate & control your systemUse the VictronConnect app to configure, monitor, update and diagnose your Smart BatteryProtect. It can connect to Victron products via Bluetooth, USB and WiFi/LAN/Internet.See the VictronConnect product page for more information.
