RE: Sounds like an excuse to buy a spot welder!




The welder's a neat little thing actually. It was cheap and can adjust intensity and duration. Powered by a suitable low internal R car battery...I just used the one from my Kei truck which was just fine.

The battery pack has a BMS which is needed as these little critters are unprotected, and high current high discharge....as they need to be in a power tool. I assume the BMS and charger talk to each other.

Funnily enough, the OEM Panasonic cells are coveted, no longer available, and commonly copied as fakes. The market? Vapers! Hahaha! The DIYers of the vaping community have their own forums etc, just like audio. They were actually a valuable source of information as to what a good aftermarket 26650 battery was.

BTW, it's not uncommon for old digital watches to have two pads or a sprung tab that need to be shorted to 'reset' the watch after battery replacement, or the watch will display a nonsense screen. I couldn't see anything like that in your pic, so didn't comment on it at first.
