i always do this if soldering batteries :
1. i use dremmel the surface of the cells and pre tin with flux.
2. then, i put a small amount solder, make sure the solder is perfectly melt, take the solder with iron, push the "turbo" button on the iron about 5 second then put it on the cells.
3. do the same thing to those battery bars.
4. solder those bars to the cells...
make sure you do it with quick & clean....
