    Super slim enough to fit behind the back seat of my triton. Came in the full setup lit and took just 3 hours from delivery to fitted and working. So easy my mum could do it. I wanted a setup that meant i didnt have to keep opening the back seat.

    This thing kicks ass.

    The slimline battery was just what I needed due to the very limited space I had to work with. Installation was easy, basically just plug and play. The remote battery monitor with bluetooth is brilliant. It looks like a rugged piece of equipment and should serve me well. Yet to use it in anger, but it has to be an improvement on my old lead acid setup!

    Impressed beyond expectations

    Excellent option for a replacement to the AGM and battery box I had in the back of my GX Landcruiser 200 Series.

    The battery has integrated Anderson plugs and USB outputs which means it's not just a battery, it incorporates the features of my battery box in one component.

    Also, it has Bluetooth battery monitoring which is a huge plus for me.

    Finally, as it's ultra-slim, I was able to remove my old battery box and AGM and mount it up out of the way and claim back my entire cargo area in the back of my cruiser, as the old setup annoyed me as it took up valuable space.
