This can be used as a stand alone device or as part of a control system for a Lithium Ion battery bank. The Victron Battery protect is a solid state relay and is used to disconnect the load from a battery when it is becoming over discharged. It is controlled internally by programmable parameters for low and high voltage or when used with Lithium Ion batteries it is controlled remotely by the the VE Bus Battery Management System
 
Solid state relay for use with 12/24 Volts DC
Operating voltage range 6-35 Volts
Maximum continuous current 100 Amps
Maximum peak current 600 Amps (30 seconds)
Power consumption max 1.5 mA
Alarm output delay 12 seconds
Load disconnect delay when triggered by BMS is instanteneous
Load disconnect delay when triggered by low voltage of 10.5 or 21 Volts is 90 Seconds
Load reconnect delay 30 seconds when voltage gets to 12 or 24 Volts
Can be programmed to behave as a 12 or 24 volt solid state DC relay
The BatteryProtect disconnects the battery from non-essential loads before it is completely discharged (which would damage the battery) or before it has insufficient power left to crank the engine. The BatteryProtect automatically detects system voltage (12 or 24 volts)
