Product Description




The McGrath 4X4 Dual Battery Installation / Wiring Kit comes with everything required to wire in a VSR based or DC to DC battery charger based dual battery system

Perfectly suited for DIY, Our installation kit requires no crimping or soldering, it’s simply plug and play.

Before deciding on creating our dual battery wiring kits we first looked at what was already available. 
What we found were numerous substandard kits that left out key safety features and left you with crimping or soldering cable lugs to cables and used undersized cable

What we wanted to create was a very simple to install kit that was safe and easy to install.

Dual battery systems need fusing at both batteries. The heat generated by a shorted 6 or 4 B&S cable is immense and can result in a fire incredibly quickly.


  • Easy to install kit

  • All crimp terminals heat shrinked
  • Fused for full protection
