Victron Energy Smart BatteryProtect 65 amps 6-35 volts Bluetooth Capable Blue. Additionally an on/off input allows the user to manually switch the device on and off. To prevent damage to the sensitive electronic loads the device is also equipped with over voltage and short circuit protection. Additionally all operations are ignition protected. The separate control logic for the two MOSFET switch units prevents ground loops which would ground the device to the negative (-) supply rail. Furthermore the device has an extremely low current draw which prevents the device from being overloaded. Due to the MOSFET switching technology the device won't get overloaded yet still allows the user to operate the device. To program the device the user only needs to connect the device to his Bluetooth device (the device can be programmed with a keypad or entered manually). Once the device is programmed the user receives an email with the activation key. The keypad can then be used to start the engine. Once the engine is running the keypad will automatically activate the VE.Bus BMS in the background and the BMS will take over all control. Specifications for Victron Energy Smart BatteryProtect - 65AMP: Manufacturer: Victron Energy Color: Blue Voltage: 24 volts Amperage: 65 amps Features of Victron Energy Smart BatteryProtect - 65AMP 12/24V Auto Ranging: The Smart BatteryProtect automatically detects system voltage one time only. Bluetooth - programming made easy: 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 (see manual). If required Bluetooth can be disabled. A Special Setting for Li-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 interrupter in between a battery charger and a Li-ion battery. See connection diagram in the manual. Ultra-low Current Consumption: This is important in case of Li-ion batteries especially after low voltage shutdown. Please see our Li-ion battery datasheet and the VE.Bus BMS manual for more information. Over Voltage Protection: To prevent damage to sensitive loads due to over voltage the load is disconnected whenever the DC voltage exceeds 16.3V respectively 32.6V. Ignition Proof: No relays but MOSFET switches and therefore no sparks. Delayed Alarm Output: The 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. Delayed Load Disconnect and Delayed Reconnect: The 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.
