    HELP - noob needs help with WF500 & 18650

    OK - removed all heatshrink from outside of cell to find surface of cell completely smooth, no bumps, no pcb, no strips nothing. If, as I am being led to believe, this is an unprotected cell then why is it behaving like a protected one? :confused: Its not that it never worked, it did work at...

    HELP - noob needs help with WF500 & 18650

    first of all, hi from a noob!! The problem I've got concerns my brand new WF500 and the batteries that came with it. It came as a package with 2x ultrafire 18650 2400mAh 3.7v batteries (the BLUE ones, not sure if they're protected or unprotected?) and the WF-139 charger. Unpacked it all, put...
