Seller: antenna_expert ✉️ (4,063) 84.6%, Location: Ranier, Minnesota, US, Ships to: AMERICAS & many other countries, Item: 161077392256 DUAL / AUXILIARY BATTERY ISOLATOR W/ CABLES-COMPLETE KIT! 150A RV BOAT CAR TRUCK.

This easy to install, high-quality system prevents discharge of your main / starting battery by drawing all 12 volt DC loads from your auxillary battery with engine off, yet charges both batteries when your engine is running. Never have a dead starting battery again!

COMPLETE KIT KINCLUDES ALL NECESSARY COMPONENTS:

  • (1) 150 amp (surge) / 80 amp (constant) battery isolation relay
  • (1) 10 foot 4 gauge high-quality water, oil, fuel resistant copper-clad aluminum cable terminated with solid copper lugs on each end. Lugs are soldered by HAND to ensure a superior connection, then heat shrink tubing is applied to protect against the elements and ensure a long-lasting, dependable cable. This cable connects the auxilary battery to one post of the battery isolation relay. All non-engine start / run loads (lights, sound system, TV, two-way radio, fans, etc.) also connect to this post.
  • (1) 4 foot high-quality 4 gauge cable (same description as above) to connect main / starting battery to the other post of the battery isolation relay. Engine start / run loads also attach to this post.
  • (2) gold plated AGU fuse holders with 100 amp fuses to fully protect both batteries and all vehicle elecrical components.
  • (1) 20 foot dual red-black 16 gauge cable with lugs to connect battery isolation relay and 3M 'Stab-Lock' connectors to connect switched (key/ignition) 12 volt positive and ground from vehicle to small posts on battery isolation relay. Relay 'closes' with key or switch (engine) 'on' connecting both batteries to charging system, and 'opens' with key or switch 'off' to isolate main / start battery from any load that can discharge main battery.
  • (1) sheet, installation instructions

*NOTE: If you have a high current / high power application (i.e., diesel or large engine, monster sound system, large inverter, etc.), please check our other listings for kits that utilize 100% copper cables that yield 40% more current carrying capability that will not overheat the cables.
