big tip on the iron!
if its small then it doesnt matter what "wattage" it is, it wont work.
the cells suck all the heat out of the iron if the tip is small and you end up holding the iron on too long and heating the cells up.

make sure your cells are tinned, I usually put a lil blob of solder on the cells so i can put the battery car on top - iron on top of that and then poke a bit of solder in..

all a bit hard to explain like, but practice makes perfect.
the flux in your solder cleans the join, solder will never stick without flux, so if youre having a problem melt a bit more solder to get some flux going, but if you have too much flux on then the solder can just bead up and float on top!.
If it gets like that, i just rub the iron around a bit on the join and the solder eventually bites..
if you get stuck on a cell for a while then leave it and do another, come back to it when its cooler and try again.


sorry that was a total mess and confused me too! lol
