I purchased protected cells just a few days after i ordered the uConsole after seeing that it shared so many components with the DevTerm. That was well before it was revealed that the uConsole was using a revised motherboard. The protected cells i have are a lot more snug, but fit without issues and without modifying the battery holder like i was originally thinking i would need to. According to the uConsole store page the uConsole’s battery holder is a bit larger allowing for a wider range of compatible cells.
