Unregulated dual 26650 box

I just finished building a dual 26650 box unregulated, the batteries are mnke 26650 with an impedence of 13 milliohms, I used 14 Guage wiring, is that enough? I'm gonna be firing a .08 build for the first fire. Should I be concerned?

This was a semi-mechanical dual 26650 parallel box mod my brother ordered..
He told me the lowest build he liked was .3 ohm, anything lower was too hot...(semi mech because it had a built-in voltmeter)
My brother gave it away when he got the 150w VW IPV3...just sayin

Those are good batteries. At .08 you are going to be drawing 52amps. If I were you, I would head over to https://www.reddit.com/r/OpenPV and ask questions about your box build. There are many of the well know box builders in the US that hang out there. But be prepared to post clear pictures and handle criticism.

edit... you can google the amp rating of the wire you are using. I seem to remember seeing 14g solid core at 24amps, but could be wrong. You also need to be using the proper mosfet or you will fry your firing switch

I like that you put them in parallel that thing must push out some real power.

What wood and 510 connector did you use?

My parallel 18650 mod pushes out more power, but this one doesn't disappoint. I glued 2 pieces of maple to a piece of oak, and I just bought the 510 and button off ebay.
