  • Power : 12V Only Power - 200 ah AGM Battery
  • Power : 12V Only Power - 200 ah Lithium
  • Power : AC/DC with 200ah AGM + 2000W inverter 30 amp Shore Power
  • Power : AC/DC with 200ah Lithium + 2000W inverter 30 amp Shore Power
  • Power : AC/DC with 400ah Lithium + 3000W inverter 30 amp Shore Power

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 2016 and newer Sprinters and Transits) that requires routing of a battery cable and signal wire from the primary battery back to the wheel well cabinet, and the installation of a chassis ground cable and shore power cable if applicable. 

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 multiple configurations up to 400 ah in capacity. 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.
