Soldering battery packs

[Elliott Hopkins]

I'm trying to knock up three 6x1 sets for Newbury on Sunday. But I'm making a real fist of it (it's my first time). I've whacked the soldering iron up to full power, but I'm paranoid I'm going to cook one of the new cells.

I need to apply an impulse of heat instead of slowly heating the cell up don't I? The bars at the positive terminals go on fine, but the bigger -ve terminals are a real asspain.

Can anyone direct me to a good tutorial on battery pack construction?

Thankyou.

Elliott.
