Flat Top to Button Top: cheap & quick 18650 conversion

I realized my Sofirn Q8 will not take flat top 18650 cells which were the only ones for sale at the time. So I had to come up with a solution:

thank you. I had a couple of 10440 cells that were flat tops, and were not long enuf to use in my Acebeam UC15 light. I’m not good at this stuff but I gave it a try, and they now work. It’s not pretty, I needed a large solder blob, a got it.

thank you for spurring me on….

Thank you! If I can do it with my unsteady hands and my cheap equipment anyone can do it :wink: BTW it is really difficult to get button tops over here at the moment. Amazon.de used to carry many lithium ion cells but those days seem to be over.
