18650_Li-Ion_battery case

thanks a lot for the person with initial design. I've only added + and - to it and made a bit longer with a bit bigger whole cutouts so that i can put thicker wires. Also I've used proper AAA battery terminals (couldn't find AA terminals). the remix is a bit rough but it was good enough for what i needed. Charging the battery of B6AC v2 via xt60 connector.
