Battery Holder for 14 21700 batteries and BMS

This was designed and used to replace the battery pack of a power wheelchair. It needs to be installed in an enclosed environment.
Two of the battery case inserts are needed to build one pack. The halves can be joined with pegs or glue. I found glue to be sufficient.
The 21700 washer is intended to protect the positive side of the battery.
This worked well for me. Use at your own risk. Incorrectly building a battery pack could result in fire or explosion.
