The protection device on my Trustfire went out.Cell will charge but with a voltmeter it will only deliver 1.5-2.0 volts,reads 1.9-2.1 volts but charger will read that it is delivering 4.19-4.2 volts. I will get using Zmax V3 screen but only for a second,I'm using thread conductive and I have a copper washer under spring for good ground. What are the dangers on non protective cells?Zmax directions say to use an unprotected cell,but it seems everyone uses protected cells. Can someone provide a link to removing protection cap? Can protection be replaced be replaced?Only 10-15 cycles on a new cell,don't really want to toss it.I can see protection cap,I cut a little of heat-shrink away and there is the protection cap.How or can it be removed?
