Solid ABS construction with multiple input and output port that provide the ability to connect a range of devices at the same.

4 x 50A Anderson style input/output ports, or 12V outlets with 10A fuses with two USB ports, a 175A Anderson-style outlet to jump-start your car using the optional battery jump cables (sold separately).

Designed to be charged direct from various sources, solar or directly from the vehicle’s main battery.

The large digital display provides accurate charge and voltage information. Built to last, industry grade, heavy-gauge internal wiring and quality connectors.

Please Note: the VSR is supplied as a kit and needs to be installed by you.

The VSR acts as an isolator for a dual battery setup. The deep-cycle battery inside the box can charge directly from the main battery while the car is running. When the vehicle ignition is switched off and battery voltage drops below 12.8V, the VSR automatically cuts the link between the deep-cycle battery and crank batteries.

Notes on VSR Kit Installation:

  • The VSR Kit Installation Instructions describe disconnecting one of the incoming positive wires from one of the four Anderson plugs to connect to the VSR
  • However, the positive wires from two of the four Anderson plugs are crimped together into one eye terminal
  • It is not necessary to split one of the positive wires off from the eye terminal, the double positive wires can be connected to the VSR
  • In doing this option, the only thing to be aware of is that those two Anderson plugs can only be used for either 12V input or output when the VSR is active, i.e. the VSR switch is on when voltage is above 13.2V
  • The other two Anderson plugs that are not connected through the VSR can be used to power 12V devices regardless of the VSR state, provided the main switch is ‘On’
