Bless this forum for being here. I have 2 poly lithion 3.7 batteries, matched pcm, 2 amp poly switch,and know where the wires go. My question is how do I attach the wire to the battery leads? Solder them on like a regular lead? Any other thoughts I should be aware of? I have read all the warnings.

Thanks agian

Hmm, depends on the battery.. Sometimes the tabs are aluminum, so you'll need some special flux and solder like here:

Sometimes there is a tin tab welded to the aluminum so you can solder to that one with normal tin/lead solder and flux.

Be sure not to overheat the cells or else you can melt the seal and the batteries will go bad pretty quick. If you think you're getting it too hot let it cool off for a bit and then try soldering it again.
