Default What solder / flux to use to solder lipo cells

the "solder tabs" on my lipo cells are made of a material that does not lend itself to normal soldering. It may be aluminum. The factory was able to solder on the original leads, so this proves it's possible. I have only tried Oatey No. 5 solder paste (good for all metals except aluminum, magnesium and stainless steel).

I have three individual cells salvaged from other packs and would like to make up a 3-cell pack.

Rosin Core solder is what I use for all electronic stuff. Hope that helps. Oh, and no flux is needed when using rosin core.

This is not standard "electronic stuff". I am fairly experienced at soldering in general. But this material (the tab that comes out of the lipo cell) is not standard steel and regular solder (rosin core or otherwise) will not stick at all. I have cleaned it very well, roughed it up a but and the solder will not stick. I think the material may be aluminum or stainless or some other metal - perhaps nickel-based alloy.
