The only thing that concerned me was after I soldered the wires to the thin tabs I bent them a little and noticed the solder peeled right off...it took with it a shiny thin metallic skin that was on the tab leaving it unshinny. So i tried to remove the rest of the shinny plating this way with no luck. I hope the solder holds!!:yikes: I tried to pick it off but it seams like it got a good bond to the tabs now. don't know what that plating is or why its on the tabs.An excellent use for this battery type. Also great for ignitions and digital cameras. Bad choice for a flight battery.
