But don't b= e suprised if it IS a LiPo and has no special protective circuitry - i've had china-made electronics just like that before (and actually I had one of those "spy cam" keyfob video recorders fail when the battery puffed up and split the case). If you're taking things apart, take the working one apart (when it is 100% charged) and measure the voltage of the cell. 4.2V would further confirm th= e lithium polymer type. Once you are sure that the cell is a Lipo, I think it would be safe to replace it with another one, if you transferred the protection electronics (if there are any). --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
