Battery Box - All in One Benefits

Why we think our battery boxes kick butt and the benefits it can bring to you and your setup!

  • All In One: Not need to get each part of the system this has it all built in and is ready to go.
  • Can remove when not using or transfer to different car vehicle.
  • Move it around when powering caravan/camp site to suit you.
  • Easy to install / Use as all the parts are inside like DCDC charger and you just need to plug it in. 
  • Plenty of grunt for all needs. 
  • All parts are matched to each other and will work out of the box.
  • Saves you time and money getting all gear installed to match. 


There a few models as can be seen in the drop down when you add to car. The difference is just some have inverters and some do not and the only other difference is the capacity of the box (How many Ah). So really the you can choose what suits you needs in terms of capacity and weight/size. If your running two in parallel then you can just choose one inverter version and one non inverter version of same size. 

  • 300Ah with inverter 
  • 300Ah without inverter
  • 200Ah with inverter
  • 200Ah without inverter
  • 150Ah with inverter


Who It Suits

4WD/Camping: Easy to use instead of a dual battery setup just put this in the back and take it out when you are not using it or leave it in there. Easy to move if you want to leave it at campsite etc. Or if you change vehicles you can take it out and move it on. 
Caravans: Pair it up with a RVD safe cheat cable and you have a safe way to give your caravan the power it needs when off gird or stopping overnight. Enough power to run AC, Air Fryer etc. Even run a 2nd one in parallel to give you 600Ah of power.  
Power Bank: Need power on the go to run different things then this will keep you going. Great system for tradies, service workers or anywhere you need to whip out your air fryer to cook a pie.

  1. Took it away for a week off-grid. Team the fridge, lights no dramas. Even used a sandwich press and a hairdryer every day. Still came home with 78%. Great all in one system.

  2. Will know more when used with caravan in future
