Converted a soldering iron to lithium power, pack welded with the UF20B — version 2
The wires in v1 were too thin and got hot, so this time I went with 2S 21700 plus a 30A BMS, and double-layer nickel strip. This machine is seriously small — it sits in a corner of the bench without taking up space, recharges in a few seconds, and I welded 40 spots in a row without ever having to wait. Best part when it was done: not a single spot needed re-welding.

Your soldering station has way too many fiddly tools and accessories, does everyone really have that many? I think simpler is better

Check out my hand-built budget T12 soldering iron, cost ¥8, dug 3 18650s out of the neighbor girl's bag and stuck them in a box, perfect right

My AWithZ sat for half a year and starved to death twice. First time a day and night of charging revived it, second time 36 hours of charging didn't, ended up sending it back. If you don't use it often, better not buy the big-capacitor kind

The 245 has plenty of play in it, you can make your own tips and graft them on
