RE: New 1100 mAh A123 available everywhere and no word here!
I have the cells ordered from RC vendor and they have no tabs at all.
I have soldered directly on the cell, like I did with 2300mAh M1 cells.
M1A 1100mAh cells are soldered much easier, no special flux is needed.
In a split of a second, the solder is done and cell terminal cooled by wet sponge.
