Reply to "Lithium Batteries - Light Weight vs Cost"

leeaMember

I'm curious, has anybody seen data that shows cold performance? Lithium ion thrives at 25'c and performance will drop as temps get higher or lower....For a car exposed to Freezing the power from the battery is hindered significantly and may prevent a start.

At least, there is nothing about the specification here that suggests less than responsible engineering and care, esp the comments on "cell balancing" and detection for safety, the use of only UL approved Cells...It also seems that the design actually works at low stress--meaning, the battery cells are operated actually below their 'nominal' voltage. This is one reason that the costs are higher (since there is a lot of potential capacity in the pack that is available, but not used), and I'd think longevity on these would be very good (more than 3 years...)--Lee
