li-ion battery pack end cap

End Caps meant for making your own Li-ion batteries (battery). These caps make it very easy to align your batteries nicely before you glue them together. They also provide some limited impact protection I will have a Youtube tutorial coming soon and will post the link here when I have finished it.

Please send me your comments as I would love to get feedback negative or positive.

I have included
2S, 3S, 4S, 5S, 6S and 8S versions for both 18650 and 21700 Li-ion batteries.

NOTE: I have not tested the 5S and 8S versions.
