I will ditto that.

 When soldering to nickel straps welded on batter cells I found no clean flux did not work well. RMA flux worked much better.

Hi Vlad - let's characterize nickel this way: in general, nickel is solderable with the aggressive fluxes. The majority of the flux formulations used by many of the High Performance OEMs are ROL0 materials which traditionally were not very compatible with nickel surface finishes.
The flux formulations being used are not aggressive.  So I have the some question as Ben - what's different about these new "solderable nickel"
surface finishes? I have subjected them to 150C bake for 4 hours and they meet the IPC-JSTD-002 testing criteria. Pretty impressive.
