Does anyone know of a current source (March 2020) for replacement batteries for the TSU3000 and 3500?
All 3 of mine have failed. The vendors on eBay and Amazon are all(?) selling general purpose battery packs that do NOT have a thermistor in them, and thus none of my 3 chargers will work with them, they just blink (error).
In the past, I have had to cut open the old dead packs and remove the thermistor and then cut open the new pack to install it. Doable, but a pain in the butt.
Or for that matter, does anyone know the correct value of the thermistor?
