Create your own portable power station.
Our heavy duty battery box allows you to turn a regular deep-cycle battery into a convenient portable power station, or create a simple dual battery setup using either a DC-DC charger or our optional 50A Voltage-Sensitive Relay (VSR) and Dual Battery Wiring Kit. It is suitable for a range of battery types including AGM, Lithium, Wet, Gel and Calcium, and can handle batteries up to 330mm (l) x 180mm (w) x 240mm (h) in size.
The battery can be charged from a range of sources (including solar panels) by simply plugging into one of the 50A Anderson-style ports. The battery’s charge status and voltage can be easily seen via the large digital display.
Key features
- Constructed from UL 94V-0 compliant fire-resistant ABS plastic
- Multiple port types allows you to connect a range of devices
- Easily connect a DC/DC charger or solar panel to charge the battery, or use the optional 50A Voltage-Sensitive Relay (VSR) and Dual Battery Wiring Kit to charge directly from crank battery
- Can be used to jump start vehicles using our optional 175A Anderson jumper cable set
- All ports are recessed into the body to reduce likelihood of damage
- Easily see battery status with large digital display
Easy dual battery setup
Using a battery box combined with a VSR is the easiest way to create a dual battery setup in your vehicle.
The VSR acts as an isolator, allowing the auxiliary battery (inside the box) to charge directly from the crank battery while the car is running. When the ignition is switched off and battery voltage drops below 12.7V, the VSR automatically cuts the link between the auxiliary and crank batteries.

Simple to install, well built, great option for DIY setups. Love it

Great box , much better than the cheap flimsy stuff , lve added a 20a dc dc mounted on top ( for air flow ) drilled 4 x 25mm vent holes high on the sides , with steel mesh to stop bugs entering
Running a 100ah lithium in it , found the volts readout is not accurate its around .5v out , rendering useless , but l have a direct link to the battery via its own monitor so it doesn’t matter , just something l noticed
Highly recommend this box , great build and price

My current set up is my first 12V set up and I'm extremely glad I went with Hard Korr.
I deliberated for a long time as to whether I go with other brands and once I saw the construction of the other boxes, which my fellow campers use (namely Adventure Kings), I was glad I went with this one.
The fittings are well organised and the wiring inside is very neat. One of the workers at a Jaycar store actually commented on how impressed they were with the finish quality under the lid.
I use this with the VSR kit which was super easy to install. I have a 2011 NT Pajero and the VSR kit works perfectly with the "smart alternator".
Some people have raised a very good point with the isolation switch sticking out so it could be prone to breaking off.
I have mounted mine easily out of the way of potential damage so it's not an issue for me but I can see the concern.
