Description

  • [VSR 2.0, Dual Battery Isolator] Equipped with the 2nd Generation 140A Voltage Sensitive Relay (VSR). Unlike outdated 1st Gen isolators, our upgraded chip features precise cut-in (13.3V) and cut-out (12.8V) thresholds. It ensures your primary battery is always charged and ready to start, automatically isolating the secondary battery to prevent total power drain while the engine is off.
  • [100% PURE COPPER & REAL 6 AWG CABLE] Don't be fooled by cheap and thin 7AWG or CCA (Copper Clad Aluminum) wires that cause voltage drops and overheating. Our kit features premium 100% pure copper 6 AWG power cables (20ft Red / 3ft Black). Rated for up to 105°C (221°F), these thick, high-conductivity cables ensure maximum current flow and zero compromises on safety for your dual battery system.
  • [EXTRA-LONG 20FT CABLE FOR VERSATILITY] Stop struggling with short cables that don't reach. Our industry-leading 20ft (6m) red cable provides the necessary length for large RVs, long-wheelbase trucks, boats, and campers. Enjoy the freedom to cut and customize the cable to your exact layout, ensuring a clean, professional installation without messy excess. Whether you're mounting the second battery in the trunk or under the chassis, it delivers the ultimate flexibility other standard kits lack.
  • [MARINE-GRADE DURABILITY & SAFE PROTECTION] Built to survive harsh environments. The isolator is IP65 weatherproof and vibration-resistant. Combined with high-quality marine battery terminals, heat shrink tubing, and insulated ring terminals, this kit prevents corrosion and short circuits. It’s the ultimate "set it and forget it" solution for off-road and marine adventures.
