You don't need a $100 iron to do batteries. Heck, my Hakko does an ok job on batteries, but
this does a WAAAY better job for $24.95. Now its next to useless for anything else in the RC world because its to big and cumbersome, but if you wanna do batteries it ROCKS.
Edit: apparently the link won't work correctly.... go to
www.homedepot.com and search for Weller. Its the 80 watt iron.
