12V power system for TK Wheel well cabinets

 TK Wheel well cabinets - with power system

This 12 V auxiliary battery system is appropriate for all full sized vans. This system is a complete turn-key solution. The only assembly or installation required is for the dual battery controller or DC/DC charger ( for Sprinters) that is installed in the engine bay and the related routing of a battery cable back to the wheel well cabinet. 

We spent a lot of time researching and testing all of the components that matched up with our requirements.. We wanted a maintenance and worry free system that was easy to monitor and charge and was programmable to allow for either AGM or lithium batteries in the future. We also knew from past experience that most battery monitors did a poor job of showing "state of charge" and we wanted a more reliable way to judge our batteries charge and health. Safety was paramount,  so all circuits and the battery are protected separately in accordance to ANSI/RVIA LV  guidelines.

Note: there is additional storage space available in all sizes of the wheel well cabinets.after the electrical system is installed.
