Did you lightly sand (or Scotchbite) each terminal and apply a thin
coating of NoAlOx before connecting? No? Then you have to redo all the
connections. They will give you no end of grief. (Ask me how I know. :-) )
If you don't do this connection treatment, the dissimilar metals will
corrode, over heat, and behave badly in general. Often, the cell
terminals arrive with a lot of corrosion formed during shipping.
Bill has it right! I've had Thundersky, CALB, and GBS cells, and *all of
them have at least one aluminum terminal. It is devilishly difficult to
make reliable low-resistance connections to aluminum.
I've even wondered if there is some way to plate them with copper or
nickel; or spot-weld some easier-to-connect metal tab to the terminals.
