The Weller WMRS should be fine as long as you flux the surfaces
properly first.  When I was building the Li-poly packs it provided
sufficient dT/dt to solder the tabs without resulting in exploding
cells later on.  Don't forget to get some tip tinner if you crank the
WMRS all the way up, I'm pretty sure we're out.
