2 Versions are available based on your requirement. Larger diameter holder and a smaller compact diameter holder.
8X 2M*6mm screws would be required along with several washers.
Drill the center hole according to your wire gauge. (2 18awg wires and 3 22awg wires fit perfectly through it)
I am not responsible for any accidents or injuries, do it at your own risk. Wire the battery carefully.
I'm a student so any tip is greatly appreciated! :)
