This 18650 case is designed to fit a 3S8P battery with the balance board.
There are 2 different designs:
The Spacer files are for people that are using the 18650 spacers to make their pack
The No Spacer files are for those who are not using the spacers. this case is slightly smaller but can't be used if you are using the spacers.
There are 4 lid styles:
No holes if you just want a cover
1 hole for just the banana plug connector
2 holes for the banana plugs and a power switch
3 holes for the banana plugs, a power switch, and a volt meter
Here are the exact parts I used that the holes are sized for

My battery pushes 30amp so I did not use the Amp meter part of that display but if your going to be drawing less than 10amp from it you can use the amp and the voltage part
The author remixed this model.
Took this amazing Project box and resized it to work as a battery box.
