These are designed to hold 12 18650B cells in parallel, and be spot-welded together (DO NOT SOLDER DIRECTLY TO BATTERIES) using nickel tabbing wire.
There is one spot in the middle for holding a temperature sensor that can come into contact with multiple cells. There is also a hole on the top that is meant to house a tap for voltage sensing of modules.
The endcaps are designed to go at the end of each bank (or string) of batteries.
