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

You use at least the LARGEST cable hooked to the battery.. Figure either battery may be called upon to deliver the total current of the load should it's partner fail "High Resistance" so the biggest cable is the jumper size.
Correct answer IMO. There is no good reason to use a jumper that is larger than whatever leads are supplying the coach. If you've got some additional large leads, for an inverter for example, you will want to at least match those, or go up a size to handle the combined load.
