Victron Energy Smart Battery Protect 12/24V--220A BPR122022000 Battery Isolator

The Victron Battery-Protect BP-220 disconnects the battery from less important consumers before it is fully discharged, which could cause damage, or before it no longer has enough energy to start the engine. Additionally, the BP series features overvoltage protection, which disconnects the load at 16 V or 32 V battery voltage, safeguarding against damage. The BP supports AGM, lead-acid, gel, and lithium batteries.

Six different disconnect thresholds are adjustable. The Battery-Protect is highly flexible and can be set to various disconnect voltages. The following disconnect thresholds can be activated on the device: 10.5 V / 21 V, 10 V / 20 V, 9.5 V / 19 V, 11.25 V / 22.5 V, 11.5 V / 23 V, 11.8 V / 23.6 V. Additionally, there are different reconnection thresholds available for most disconnect thresholds. This makes the device the perfect protection for your battery, ensuring maximum lifespan, as most voltage converters or charge controllers do have undervoltage protection, but this typically activates at quite low values, usually around 10.5 V / 21 V. The higher the disconnect threshold, the longer you will enjoy your batteries, which are generally quite costly.

The selection of the disconnect threshold depends on the battery type, as different minimum battery voltages must be adhered to in order to avoid damaging the battery.
