    Operating Lithium Batteries In Cold Temperatures

    Holy shit you're obnoxious. I came to an engineering forum because I would like the help of an engineer to decipher this information. I have no idea what battery these images are based on. They start out at above 4V, so obviously not the one I'm using. If you're not going to help, please go away.

    Operating Lithium Batteries In Cold Temperatures

    I know that cold temperatures will impact the performance. What I'm asking is *how* it will affect performance. Will the voltage drop? By how much? I need to know that to design the circuit.

    Operating Lithium Batteries In Cold Temperatures

    This is not for drinks. It is for a large ice globe for decoration. I would obviously have to seal everything up to avoid short circuits. It takes a while for a globe that big to freeze, and I want to be able to make them well in advance. Hence why I can't use one of the commercially available...

    Operating Lithium Batteries In Cold Temperatures

    I'm assuming that freezing temperatures will affect the performance characteristics of a Lithium-Ion battery. What I'm trying to accomplish is making these: http://samjacoby.com/projects/ir-led-throwies/ And then freezing them inside spheres of ice. How will operating in these conditions...
