Smart BatteryProtect Victron

The Smart BatteryProtect 12/24V from Victron Energy offers solid battery protection for 12V and 24V batteries of various types. Compared to the previous series, the Smart version has an integrated Bluetooth module that connects the Smart BatteryProtect to a smartphone or tablet. This allows you to program all the required switch-on/switch-off thresholds or set the appropriate value from 9 predefined thresholds.

The BatteryProtect 12/24V can also be used as a charge interrupter between the battery charger and a lithium battery. A wide operating voltage range of 6-35 V makes the device universally applicable. The ability to connect an external switch or alarm to the BatteryProtect makes it the perfect battery monitor.

Features of the Smart BatteryProtect 12V/24V-65A

• maximum switching capacity of 65A, 100A and 220A (depending on the version)
• For 12V and 24V batteries with automatic detection of the voltage range of the battery bank
• Explosion protection through integrated MOSFET switches that replace the relays and thus reduce the risk of sparking to zero
• integrated Bluetooth module, can be switched off optionally
• freely programmable switch-on and switch-off thresholds, easily and wirelessly via the VictronConnect app
• alternative programming and status display of the settings via seven-segment display possible
• integrated alarm output, 9 predefined thresholds selectable
• An external alarm, LED or relay can be connected to the alarm output
• via relay, the load shedding of the BP can be controlled by external events that cannot be programmed in this way

output for delayed alarm

The alarm output is activated when the battery voltage falls below the preset shutdown level for more than 12 seconds. Therefore, turning 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.

solid battery protection for every battery type

Thanks to its wide range of configuration options, the Smart BP-65 is the perfect protection device for your battery and ensures maximum service life. Although most voltage converters or charge controllers have undervoltage protection, this only kicks in at fairly low values, which are usually in the range of 10.5V / 21V. The higher this cut-off threshold is, the longer you will be able to enjoy your batteries, which are usually quite expensive.

selection of the shutdown threshold

Depending on the battery type, different minimum battery voltages apply that must be adhered to in order to avoid damaging the battery. For AGM/gel batteries, we recommend setting the Batteryprotect to a 11.5V cut-off threshold. For lithium batteries (LifePo4), a 12.0V cut-off threshold is recommended. Depending on the intended use of the battery, it may be necessary to change these limits. Manufacturers also provide different information about their batteries. Therefore, always check with the battery manufacturer which cut-off threshold is correct for your battery!
