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 that 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 very 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 reconnect thresholds available for most disconnect thresholds that can be chosen. This makes the device the perfect protection for your battery, ensuring maximum lifespan, as most voltage converters or charge controllers have an undervoltage protection that only activates at quite low values, typically around 10.5 V / 21 V. The higher this disconnect threshold is set, the longer you will enjoy your batteries, which are generally quite costly.

The choice of disconnect threshold depends on the battery type, as different minimum battery voltages must be maintained to avoid damaging the battery.
