Tesla 21700 battery holder. NO WELDING !!!
thingiverse
Everybody know Tesla 21700 elements has a aluminium positive contact. As I know, reliable way how to solder or weld it in to one battery not exist.I designed this holder to make battery from 1S1P to 12S or 6S2P easy and reliable. You can print one, two or more boxes and connect it in to battery via 8mm x 0.15-0.2mm nickel string without soldering or welding. You can combine different holders to get needed battery configurations.Battery siiting in place pretty tight and has a good and constang contact.I used PETG with 0.5mm line width. No support required.IMPORTNAT NOTES: when you will insert battery in to holder slot - do it fast, due to some spark possible. And also you MUST fix all 21700 elements in holder to prevent its movement.
