The Smart BatteryProtect 12V/24V-220A from Victron Energy (MPN BPR122022000 ) offers solid battery protection for 12V and 24V batteries of various designs. Compared to the previous series, the Smart version has an integrated Bluetooth module that connects the Smart BatteryProtect (Smart BP-220) to a smartphone or tablet. You can program all required on/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 the BP-220 Smart the perfect battery monitor.

Performance characteristics of the Smart BatteryProtect 12V/24V-200A

  • 220A maximum switching capacity
  • 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, optionally switchable
  • 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 threshold values ​​selectable
  • an external alarm, an LED or a relay can be connected to the alarm output
  • The load shedding of the BP can be controlled via relays by external events that cannot be programmed in this way

Delayed alarm output

The alarm output will be activated when the battery voltage falls below the preset cut-off value for more than 12 seconds. Turning on the engine will therefore not activate the alarm. The alarm output is a short circuit protected open collector output connected to the negative (minus) rail. Max current 50mA. The alarm output is normally used to activate an acoustic signal, an LED or a relay.

Solid battery protection for every battery type

Thanks to its wide range of configuration options, the Smart BP-220 is the perfect protective device for your battery and thus ensures a maximum service life, because most voltage converters or charge controllers have an undervoltage protection, but this only intervenes at fairly low values, which are usually in the range of 10.5V / 21V. The higher this switch-off threshold, the longer you will be able to enjoy your batteries, which are usually quite expensive.

Note on deep discharge protection:

When using the Battery Protect in connection with voltage converters, there may be problems with the restart function.Larger VT models (>1500W) may require very high capacitor current during power-up, which may put the BP into error mode. This can be circumvented by briefly cycling the VT.

The protective function of the BP remains.
