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.
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.
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!
