There is a need to replace 45, 90, 180,
etc. Volt dry batteries using common 9 Volt batteries and an
adapter. This is my first attempt at a 45 Volt stick. It
has been designed to allow connection of multiple sticks in series to
get the higher voltages. It also has large snaps on the top to
emulate the 455 45 Volt battery electrically, but it is not physically
the same size as the 455 battery.
There are narrow spots on the traces to each of the big snaps so that
the snaps can be electrically isolated from the local batteries.
At the left and right side in the photo below there are jumper
positions to allow a series connection of the sticks to make 90, 180,
etc. voltage battery packs.
