Electronics and technology blog    /    Materials for September 2023 year

In today’s world, there are many electronic devices, and progress is driving them toward ever-smaller sizes. Repairing them with a “grandpa’s” soldering iron is becoming increasingly difficult, though there are still areas where one can come in handy. But today we’re not talking about soldering irons. We’re looking at much more sophisticated equipment, intended not so much for home use as for professional applications.

As luck would have it, I got my hands on one of the new batteries from Molicel. It’s a very interesting cell, primarily because it combines relatively high capacity with a high rated discharge current. Inspection, tests, comparisons, conclusions—the usual.

I’m often asked about batteries, building battery packs, and where to buy cells without ending up with junk. Today I have a short article and video on the subject.
