Sure - didn't mean that I'd use duct tape to form the electrical
connection, just to sheath the soldered-together pair so the will fit in
the same slot as the old pack, within the torch's body.

Most RC model (rather than toy) shops will sell both cell sized
(diameter) heat shrink and also straps to solder across non tagged
cells (as used with many top spec and diy racing packs). However you
will really need a big iron to solder them properly.

You could also buy the cells there etc.

Unlikely to buy single cells.

Try here

However these are not tagged, but can be still used: the technique is to
abrade and pre tin the surfaces to be soldered with a big hot iron, then
laying two cells in a channel use a hammerhead tip
(http://www.cheapbatterypacks.com/?ap...=GF132BCD6B)to
heat the solder between two cells, then slam them together as the iron
is removed.


Better to buy fro the USA for cheaper cells

Those guys will also sell you a pre soldered pack made to your specs
with flying leads, if the problems of constriction are beyond you.

I got a price of $12 for a two cell sanyo 1700 sub-C pack...
