Victron Battery protect with Bluetooth Capabilities, 48 volts, and 100 Amps
p/n: BPR048100400
Availability: In stock
This is the 48 Volt version of the popular Victron Battery Protect.  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 48 Volts DC
  • Operating voltage range 24-64 Volts
  • Maximum continuous current 100 Amps
  • Maximum peak current 250 Amps
  • Power consumption max 2.0 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 48 Volts
  • Can be programmed to behave as a 48 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. This BatteryProtect is only for 48 volt systems

The BatteryProtect can be set to engage / disengage at several different voltages using the seven segment display to indicate which setting has been chosen.  For Li-ion batteries the Battery Protect can be controlled by the VE.Bus BMS. The Ultra low current consumption is important in case of Li-ion batteries, especially after low voltage shutdown. This is a solid state device using MOSFET switches instead of relays and so is ignition protected.

The alarm output is activated if the battery voltage drops below the preset disconnect level for more than 12 seconds. Starting the engine will therefore not activate the alarm. The alarm output is a short circuit proof open collector output to the negative (minus) rail, max. current 50 mA. The alarm output is typically used to activate a buzzer, LED or relay. The load will be disconnected 90 seconds after the alarm has been activated. If the battery voltage increases again to the connect threshold within this time period (after the engine has been started for example), the load will not be disconnected. The load will be reconnected 30 seconds after the battery voltage has increased to more than the preset reconnect voltage.
