This is our basic entry-level auxiliary battery installation kit for those on a tighter budget, and those with minimal power needs. Read more in the 'Power Needs' tab.

Fits: All 1983-91 Watercooled Westfalia full campers, and powers your camper's sink, stove, fridge, and stereo.

For the following battery types: Flooded, Sealed Lead-Acid (SLA), and Absorbed Glass Mat (AGM) batteries. Not recommended for use with Lithium Iron Phosphate (LiFePo4) batteries.

Includes wiring, battery isolator solenoid, 50A circuit breaker, fuse holder, battery hold-down clamp, electrical connectors and instructions. This easy-to-install kit is designed to charge a second deep cycle battery (to be located under the drivers' seat) while the engine is running and isolate it when the ignition is off. This kit includes detailed, color instructions that allow you to rewire all existing interior accessories (such as lighting, stereo & cigarette lighter/12V outlet) to the new auxiliary power source. You can then safely run your electrical devices from the auxiliary battery without depleting the charge of your primary starting battery.

NOTE: If you also need a battery, please see our SLA1161, or purchase our Auxiliary Battery Bundle to save a couple bucks. 

*If you prefer to buy the latest technology we offer, pick up a GW-LIFEPO Lithium Iron Phosphate battery, a Renogy DC-DC Charger, and our Installation Kit. Or, save a few bucks by picking up our Deluxe Auxiliary Battery Bundle.
