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

I use #4 store-bought for that job. Never a problem. Length depends on how close you get the batteries to each other--end to end or side by each. Be sure to balance the load though, so each battery takes about half.
That is, put your inverter and other wires across the pair with pos to one battery and neg to the other battery
If you want the load wires to go to the same end of the pair, put your parallel links cross-wise X so your load posts are both closest to the inverter or whatever.
I would use two #1 from inverter to batteries as short as you can in the set up.
I see the point above about if one battery fails the other takes all the load, but IMO in real life the one battery would then have such a voltage drop the inverter would shut down and now no problem!
