If you actually checked the specifications for electrolytic capacitors
you would have noticed that they're all specified to work a low
temperatures, you just need to take into account the temperature
dependence on their performance.
Which we have done, so although our boards are not specified to operate
below zero, as we can't get all parts specified for that, they're
otherwise designed to. And a lot of customer use them like that without
problems, you can usually expect our boards to work down to about -30 degC.
