battery wiring

planning on making a duo 18650 mod with both batteries in parallel question being that in parallel in theory 2 18650 batts at 2600 mah each would have a total capacity of 5200 mah and each battery can push up to ten amps so in parallel would both together should push 20 amps?

Correct. In parallel, capacity and current capability are combined, and voltage remains the same.

I don't think you should make home grown battery packs with lithium batteries. If one feeds the other (such as if they are not balanced in charge or not the same age), it can explode or catch fire. You can buy circuits that are intended to make packs, but you can't just connect the batteries in parallel. Good luck (and don't explode).

Good point! Important for stacked batteries (in series) not so much so for parallel, as they share the load. Albeit I would still use new batteries in the set up and always keep 'em in pairs.

I guess my goal is to achieve the high drain characteristics of high drain along with high capacity
