There is nothing on this item that falls short of my expectation, even a functional protective bag and a spring loaded, fold flat carry handle, great!

Photonic Universe is an official distributor of products from Victron Energy - the globally renowned manufacturer of high quality hybrid power electronics. Victron Energy products have a longstanding reputation for their outstanding reliability, innovative design and superior build quality.

This Victron 100A 12/24V automatic battery protector offers protection for the discharging of your battery system, preserving your battery health and protecting appliances.


  • Low voltage disconnect: when battery charge is low, the Battery Protect disconnects the battery from nonessential loads to avoid deep discharge and preserve battery health.

  • Programmable low-voltage threshold: easily customise the disconnect threshold based on discharging needs.

  • Overvoltage disconnect: when battery voltage gets too high, the BatteryProtect disconnects the loads to protect them from damage.

  • Automatic system recognition: the BatteryProtect detects the system voltage (12V or 24V) on start-up, allowing easy installation and setup.

  • Ultra-low current consumption: avoid further drain on the battery to preserve battery level, especially after low voltage disconnect.

  • Remote switch and alarm connections: connect input and output relays to control the BatteryProtect remotely, manually turn loads on and off, and use custom alarm systems.

  • Compatible with Lithium batteries: specialised modes for use with Ve.Bus Lithium battery management systems, and as a charge interrupter for Lithium charging.
