If you want to
save your expensive LiPo battery packs from serious damage, then this is the
temperature label for you!
These neat devices are
unique temperature monitoring labels that can be used for monitoring the
temperature of your Lithium Polymer (or even Lithium Ion) Battery packs.
Lithium batteries are very sensitive to high temperatures and without monitoring the
pack's temperature, you can severely shorten the battery's life expectancy, if
not ruin the battery (or worse yet, cause a FIRE!)
thin, flexible temperature gauge labels are specifically designed to monitor
temperatures that range from 86 degrees to 140 degrees (Fahrenheit). These
labels also include a strong self-adhesive tape... all you need to do is peel
off the release paper on the back of the label and then apply directly to your
seven (7) indicating digits becomes easily visible as temperature increases.
Digits change from black (invisible), through the color spectrum, then back to
black as the temperature decreases (i.e. "reversible"). These are designed to
monitors temperatures from 30° to 60°C / 86° to 140°F. Rugged, unbreakable
construction without glass or plastic parts to shatter.

How They Work
The molecules in the liquid crystal thermometer are made of cholesterol, and
are called cholesteric liquid crystals. The molecules are rod-shaped. The rods
form layers in the liquid crystal, the rods in adjacent layers running in a
slightly different direction from those in the layer above or below. From one
layer to the next the rods form a structure like the stairs of a spiral
staircase. The spiral staircase rises through some distance before the molecules
twist around parallel to their original direction. When this distance equals
half-a-wavelength of BROWN light, the liquid crystal
will reflect BROWN light. When the distance is shorter,
matching half a wavelength of blue light, the crystal will reflect blue light.
(The wavelength of light is measured in the liquid crystal and is shorter than
the wavelength in air.)
The liquid crystals are usually encapsulated, packaged in microscopic plastic
This allows the material to be cut. they are also thermally rugged which allows
be laminated to protect them from hard handling in a high temperature laminating
