I wanted to replace the battery pack in an old Black and Decker HC300 Dustbuster, so I looked up replacements and found one listing on aliexpress. The price isn't too bad, but I don't really want to wait ~3 months for it to arrive. I thought maybe I could source some of the individual Sub C cells locally and make my own instead. Is there anything I should be aware of when creating a battery pack out of these? Do I really have to buy ones with the little tabs on them and solder them together, or can I just have them touching like you would when sticking two AAs in series in a device?
