These are solderless caps for Tesla Model 3 Batteries (21700) to build your own battery pack. Batteries are $2.49 available at [Big Battery 21700](https://bigbattery.com/product/model-3-2170-cells-w-cap-box/ "21700 Cells") Designed in TinkerCad, the cell cap is available here: [21700 Cell Cap](https://www.tinkercad.com/things/6coSHTIBZYW "21700 Cell Cap") and the Cell Cap Corner is available here: [21700 Cell Cap Corner](https://www.tinkercad.com/things/1shPb0KE9VC "21700 Cell Cap Corner") The holders are for Tesla Model 3 style 21700 Batteries. For this build I bought 100 batteries (98 are used for a 14s7p battery pack that is 52 volts and 35 amp hours). You can purchase the batteries for $2.49 per unit at [Big Battery](https://bigbattery.com/product/model-3-2170-cells-w-cap-box/) The machine screws and nuts can be purchased at [Bolt Depot](https://www.boltdepot.com). This is what I ordered for my 14s7p batter pack.
