What are my 18650 laptop pull cells useful for?

@Sirstinky Where are the temperature sensors for temperature protection? If they don’t also measure at the battery I suppose that leaves a safety risk. In general, medium or high would be plenty, but I’m trying to get a broad sense of the safety risks.

@Cereal_killer According to New Sofirn SP33 V3 !! - #3 by Lux-Perpetua the SP33 v3 is now using a FET driver instead of a boost driver, and seems basically identical to the EC01.

It would be great to have clarity on when it’s 100% safe or not. Sounds like the drivers and other electronic protections are the determining factors, and I’m not too knowledgeable on that topic yet.
