<div class=Section1>
<p class=MsoNormal>I’m having trouble getting ordinary silver bearing
solder to flow and bond with the metal tabs at the end of some 5000 mAh LiPo cells.
What’s interesting is that I can re-solder to any spot where it was
originally soldered by the manufacturer, but I can’t start a new solder
joint. I’ve tried extensive cleaning of the metal, no luck. Does
anyone know what the material is that those tabs are made from? Is it an
aluminum alloy of some type?<o:p></o:p></p>
