Making End to End Stick Packs
by Charlie White
With the right tools and just a little practice,
it is not difficult to make your own battery packs.
TOOLS:
1. A Weller SP40 soldering iron.
2. A "hammer head" soldering tip.
3. Solder - a 60/40 lead solder.
4. A "V" block/form to hold the batteries.
5. Some way to clean the battery terminals
6. Emery paper to keep the tips of the soldering iron clean.
HOW IT IS DONE
1. Clean the battery terminals with a wire brush,
emery paper, or what ever will work for you.
2. Very lightly tin the battery terminals to be
joined together. Lightly tinned means a small amount of solder
applied to the terminal(s) with the hot soldering iron in a area
about the size of the end of a pencil easer. Be careful, NO blobs of
solder.
3. Place the batteries into a "V" block or some
type of a cradle/holding devise.
4. Place one tip of the soldering iron against
the + terminal and the - terminal against the other soldering iron
tip. Count "1 Mississippi, 2 Mississippi, 3 Mississippi" and maybe a
"4 Mississippi", depending on the air temperature.
5. Pull the soldering iron up and away form the
batteries and GENTLY press the batteries together. DO NOT press the
batteries together too fast or too hard as the molten solder can
splatter creating little balls of solder between the terminals.
All very simple and very easy!
Batteries can be separated while holding the
batteries, one in each hand, with a quick, positive, strong snapping
movement.

There are many Advantages of soldering batteries
is way. The first one being that once you build your first packs and
get good at doing it, its a very fast way to build packs. Its
cheaper then using battery bars. Less resistance then battery bars.
The packs built this way are narrower then side by side packs. Cells
are soldered together quicker, so less damage to the cells from
overheating them while putting on battery bars.
The only disadvantage of building them this way
is its harder to disassemble the built pack if one battery in the
pack dies. A trick to breaking them apart is putting them in the
freezer, then twisting the cells in opposite directions. Sometimes
the cells may become damaged.
