The Victron Battery-Protect BP-100 (MPN BPR000100400) disconnects the battery from the less important loads before it is completely discharged (which would damage it) or before it no longer has sufficient energy to start the engine, etc. The BP series also has an overvoltage protection which disconnects the load at 16V or 32V and protects it from damage. In addition, the BP series has overvoltage protection that shuts down the load at 16V or 32V battery voltage and prevents damage. The BP supports AGM, lead-acid, gel and lithium batteries.6 different switch-off thresholds can be setThe Battery Protect is very flexible and can be set to different switch-off voltages. The following cut-off thresholds can be activated on the device: 10.5V / 21V, 10V / 20V, 9.5V / 19V, 11.25V / 22.5V, 11.5V / 23V,11.8V 23.6VDIn addition, there are different reset thresholds that can be selected for most cut-off thresholds. This device is the right protection for your battery and ensures a maximum lifetime, because most voltage converters or charge controllers have an undervoltage protection, but this only intervenes at quite low values, which are usually in the range of 10.5V / 21V. The higher this switch-off threshold is, the more the battery is protected. The higher the cut-off threshold, the longer you will be able to enjoy your batteries, which are usually quite expensive. Selection of the cut-off thresholdDepending on the battery type, different minimum battery voltages apply that must be adhered to in order not to damage the battery.
