What gauge wire needed to parallel 12v deep cycles

What gauge wire do I want to parallel two deep cycle group 27 batteries? The system will run through a 1200 watt inverter.

Thanks

  • After dividing 1200 by 12, dig out your trusty amperage chart. Your inverter manual will tell you.
  • Look in commercial boat stores for battery joining ready made jumpers. Likely 2 would be enough. Consider 0 for feeding your inverter if you actually plan on running 1200 watts for more than a few short minutes. 1200 watts = 100 amps times 12 volts.
  • Go biy some O welding cable and have some ends ceimped on. Best investment you can make
