Product Description


The all new KickAss Ultimate Battery Box is a breakthrough design providing and all in one plug and play solution for providing auxiliary power outlets, charging and isolation of your 12 volt deep cycle batteries. Featuring an advanced built in and ultra powerful 25 Amp 3 Stage DC-DC Charger / Isolator system, the  Ultimate Battery Box is able to correctly charge a variety of battery types including AGM from multiple sources. Charging can be either from the vehicle as well as solar panels or separate DC sources and impressively they can charge all at the same time!

For solar charging an inbuilt MPPT regulator is built in for maximum efficiency. All of the charging sources can be easily connected to the Ultimate Battery Box by the 50A Anderson style battery connector points, making it truly plug and play, no complicated wiring is required, all you have to do is purchase a KickAss 12 Volt 120AH KA12120 battery and install it into the box!

Another great and equally important feature of the Ultimate Battery Box is its built in battery isolation technology. This fantastic feature will automatically ensure your vehicle's start battery is fully disconnected from the Ultimate Battery Box when your the engine is off an not charging. This means that the Ultimate Battery Box will never drain your start battery when the vehicle is not running.

The Ultimate Battery Box is also packed full of standard and heavy duty power outlets to cater for for everything from charging your phone or digital camera, to powering your fridge or higher current devices (see the specifications tab for a full listing of all the included outlets). It even includes a LED display volt meter so you can easily check your battery charge at the push of a button.
