Copper pipe connector bars...any issues?

[Solarfun4jim]

I'm wondering if i could use two copper pipes (22mm + 12mm), putting the smaller one inside the larger, and beat them flat with a mallet to form a solid copper connection bar, to hook 3x 48v(100A discharge rate) lifepo4 battery packs in parallel. Any easy calculators to see if the copper pipe over say a 2 foot conductor length, would safely carry the amperage? .....(either that i need to get me some lightning conductor copper banding(lol).

I have seen others use it for battery jumpers, etc. It isn’t the same as electrical cables designed for power transmission. Oversized to accommodate resistance would be wise...
try a google search for using pipe for conductors...
