Anyone has ever tried to put A123 on Gorilla chassis?

I believe there is a vent on one end, and a filling hole that is sealed on the other- I foregt which end each is on. As for soldering, you just go around them- I used a piece of 14g wire either side of the vent, though you can buy special A123 battery bars that even have a hole in the middle for balance tap wires:
