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 try and choose each part of the system. We have done it and matched each part to each other. 
  • 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. No $$$ for installing dual battaries or multiple parts. 
  • Easy to Use as all the parts are inside like DCDC charger and you just need to plug it in. 
  • Plenty of grunt for all needs 3000W (6000w Peak) and 300Ah
  • 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. 

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. Plus if you want to power something external you can treat your car like a battery generator and power caravan with the normal 240V RVD lead. 
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. Or install it in your caravan and that is your battery setup done. 
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.

Compare To Others

What else is out there. So you have the option to buy all the parts and build your system so that is a DCDC charger, Solar Charger, Battery, Inverter etc. We will not even cover that. But we will look at other lithium battery boxes and see what we have. Remote box with USBs, Anderson Plugs, Cigarette Plugs for running 12V further from box.

  • RedArc -100AH GOBLOCK PORTABLE DUAL BATTERY SYSTEM – Great brand but this is only a 100AH and has no inverter and we have heard issues with the DCDC charger when it gets warm. Plus its $3198.00. So you are missing out on 200AH extra amp hours that we have and also no inverter. 
  • BLUETTI AC180 Portable Power Station | 1,800W 1,152Wh – $1099 but not really in the same level this would be ideal more for camping and just charging laptop, running lights etc. It really does not have enough capacity to suit our market as you have to think even a car fridge will pull on average 3-4 amp per hour so over 24 hours that is 84Ah. 


  1. You will need to use the brackets provided to mount it where you need it or use straps to mount it down as it is heavy and you do not want it to move.
  2. You will need to run a + and – cable fro m your main battery and a ACC power cable to the DCDC input to allow charge from your car. It will charge only when the car is running and will work fine with smart alternator’s. 

You just need to download the app onto your phone and then you can open the app you will be able to see power usage, charger and capacity. 

Like all our products you will get a 3 year warranty on it!
