Introducing the Auxiliary Power Distribution System

Easy dual battery installation

The Auxiliary Power Distribution System (APDS) replaces many of the bus bars, fuse blocks and ring terminals typically used to build power systems for 4wd/off-road trucks, vans and RVs. All of the DC-DC charger, solar, auxiliary battery, start battery and ground connections can be routed through the APDS for a super clean and painless install. There's really no easier way to wire up your dual input DC-DC charger!

Make connections in seconds

All Tesota Overland products use genuine Wago connectors, just strip the wire or cable and insert them into the labeled connectors. No crimping or other tools required.
