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

Single aught twelve inches in length can pass 900 amps continuously with very little volt drop. The problem with using extremely heavy cable is lateral shear force on the battery terminals. It doesn't take much to shear Pb. I dislike the work but I resoldered dozens of battery terminals a majority of which were caused by a loose cable in a 24-volt system failing under a starter motor load.
I see now Silicone 1 AWG is available on eBay. This stuff is far and away the most flexible electrical cable I have ever worked with. It is to welding cable what welding cable is to THHN construction wire.
I have seen idiot sailboat builders connect a 120 amp alternator with 2/0 cable. The ring terminal is frightfully close to the bearing boss.
the 150 amp charger I am building has several short-length 6 gauge component to component bridges of silicone wire. The actual charger to clamp duplex wire is # 2 cable.
I base my decisions on electrical engineering discipline plus actual MEASURED full potential voltage drop. Methinks many misjudgements are afoot :)
