Mini spot welder
« on: July 17, 2023, 17:01:03 PM »
One of those things that as soon as you try go “why I did not buy one earlier!”  ::)

As I am slowly transitioning to Li-ion batteries, like my good old niamh packs, I decided to make them myself and after doing the usual soldering, decided to invest in a mini spot welder.
And God, I should have invested way sooner! Makes batteries in minutes, clean and very strong!
Did a couple of spot weld on a 1850 battery, and could not tear apart the nickel that was welded with pliers!

Anyway, look at the photos, took me 5 minutes to weld those batteries, and already looking forward to my next batch 😁

For info, there are tons of those spot welders available, the one I have is the SeeSii spot welder. Came with what looks like a lifetime supply of nickel strip, usb charging cable, battery holders and a small file to clean up the connections.
Education is important, but flying RC planes and gliders is importanter!
