In-Vehicle DC-DC Battery Charger (R2-0) InterVolt system is a necessary part for your vehicle and overall off-road experience.

The DCC Pro is built to withstand the harsh conditions of Australia making it the perfect product to fit the needs of the South African off-road enthusiast. The unit is a standalone power conversion device designed to charge and maintain any auxiliary battery in an installation where the starting battery is used as the supply source. 

The DC to DC charger allows you to charge from two inputs (alternator and solar). In comparison to the previous model the DCC Pro 2.0 offers a 25 amp output, limited input and 3 stage solar charging. Along with updated charging algorithms, a 30-minute ‘short stop’ has been implemented so as to allow the DCC to resume working if the charge cycle is interrupted. A 4 metre lead comes standard with the kit. Display now shows input type DC (main) or PV (solar) and charging stage. Alternate screen shows battery type.

No modifications are not required to install the system ensuring the manufacturing electrical system is not compromised.  Furthering enhancing the worth of having in-cab display which in the end improves your overall journey.
