Electrical

Electrical is the backbone of a modern overland build — it keeps fridges cold, lights bright, devices charged, and communications live far from the grid. This collection spans the full 12V system: auxiliary battery and DC-DC charging, power distribution and switching, solar, portable power stations, Starlink and satellite power, brake controllers, and the wiring that ties it all together.

National Luna's DC-25 and DC-40 power packs and distribution boxes anchor the dual-battery side; Big7Kits builds vehicle-specific battery cable kits for Tacomas, 4Runners, Land Cruisers and Wrangler JKs.

Before you buy anything, add up your actual power draw — a system matched to real loads beats one sized by guesswork.
