Here is the rewritten text: Here's a box to assemble a 6S Li-ion 21700 battery. Designed as a drone battery case, it also works well for a TS100 soldering iron ground battery. It includes a balancing port and an XT60 port. The 3D printed parts are: the cover, the top, the welding jig, the centering triangle, and the bottom. Transport plugs for the ports are made of TPU. You'll need: Samsung INR21700-40T 4000mAh - 35A batteries available here: https://www.nkon.nl/samsung-inr21700-40t-4000mah-30a.html Nickel sheets 0.15x8x100: https://fr.aliexpress.com/item/32962881106.html Silicone cable for balance wires 24 AWG: https://fr.aliexpress.com/item/32835871902.html XT60 connectors: https://fr.aliexpress.com/item/32955886178.html JST XH 7P balancing connectors: https://www.amazon.fr/gp/product/B079MJ1RYN/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1 Lead, soldering iron, hot glue I made a spot welder using a microwave transformer and a control board. https://fr.aliexpress.com/item/32808302953.html I printed the cover and top together at the same time (see Simplify 3D screenshot), which saves supports and produces a nice finish. Avoid applying too much pressure, or you may encounter issues separating the cover from the top. Note: Be careful with the XT60 and JST connectors, as their pins are exposed! You'll need transport plugs made of TPU to handle them safely. It weighs 460g.
