Step 1: Location, Location, Location!

Decide where to install your GoFurther battery box with the integrated iTECHDCDC25 charger. It could be in the back of your ute, in a canopy, on your boat, inside your camper trailer, or even securely in the back seat of your car. This versatile setup allows you to customise your power source for your unique adventure.

Step 2: Drop-In Your iTechworld Lithium Battery

Place your iTECH100 or iTECH120X PRO battery inside the GoFurther battery box, designed to accommodate your lithium battery and integrate our innovative iTECHDCDC25 charger. The iTECHDCDC25 is unique because it features dual inputs: one from your vehicle's cranking battery and the other from solar power, utilising cutting-edge MPPT technology.

Step 3: Plug and Play

Our Plug and Play Wiring Kit simplifies the connection process. One end connects to the GoFurther battery box, while the other links to your vehicle's cranking battery under the bonnet. This intelligent system allows your cranking battery to activate the iTECHDCDC25 charger, ensuring efficient charging for your lithium battery.

Step 4: Take it Anywhere You Need it
