My spare 18650 cells are tagged but one tag on one cell had broken off, the spot welds have failed. I would not attempt to re-attach it by soldering. The other two cells could have their tags removed so I could end up with three un-tagged cells, which could be recharged individually in an individual cell (as opposed to bundled cells) 18650 charger.
Another possibility occurs to me, I have a good supply of Makita 18 Volt professional power tool batteries, I could easily get a broken drill or other suitable tool and cannibalise the battery mount. These batteries have capacities of 3Ah and 4Ah, well more than enough to power the Astro Mount for days, weeks even!
Why, oh why, are all these batteries different. The cells inside are largely the same, as are the voltages, yet each manufacturer has their own proprietary style of attachment and termination.
