Effective lifetime of... forever. no need for replacement. insanely fast recharge. smaller (probably). What's not to like? I am not in a huge hurry to get into manufacturing, and I merely wanted to cost out what what it would do to the bom, any changes to the PCB, and get an estimate for the time it would take to do. I think it will bump the unit cost up slightly, but what price, forever? > -- > =A0 =A0 =A0 =A0 =A0 =A0 =A0 =A0Eric= S.
