The Victron Energy 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. 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 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 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.• 12/24V auto ranging• Bluetooth programming made easy• Instant readout• Special setting for Li-ion batteries• Ultra-low current consumption• Over-voltage protection• Ignition proof• Delayed alarm output• Delayed load disconnect and delayed reconnectSpecsMax Continuous Load Current: 65APeak Current: 250AOperating Voltage Range: 6 - 35VCurrent Consumption: 1.4mAIP Rating: IP67Connection: M6Dimensions: 1.9"H x 2.2"W x 4.2"D Uni-directional device can only deal with current in one direction Bluetooth programming made easy with instant readout Over-voltage protection & ignition proof | Expion360 Victron Energy Smart BatteryProtect 12/24V 65A in Blue
