These brackets allow you to connect multiple of the 6s2p 18650 spacer holder by vapgames together to create a larger battery pack without the need for screws. I used the holes already present in the design to make a bracket to connect many of these in series. There is a screw on version, but the screws get in the way of the nickel strip and take a really long time to install. So, I made this pegged version that allows for quick and easy install. Now you can attach these holders together to make whatever battery pack you need!
