Hey, co-founder here. It's very forgiving to temperature. Supercapacitors don't store energy using a chemical reaction, which make them a lot less finicky. On the low side, our power architecture also allows us to boost the voltage slightly if we sense that its cold outside, so we can account for the increase in resistance. It's also still go superior lifetime at high temps as well.
- chillingeffect 11y agofwiw, Wikipedia says "The lifetime of supercapacitors depends mainly on the capacitor temperature and the voltage applied." [ 1 ] This picture shows a 10x decrease in life when the temp varies from 25C to 65C: https://en.wikipedia.org/wiki/File:EDLC-Life_time_curves.png https://en.wikipedia.org/wiki/File:EDLC-Life_time_curves.png [ 1 ] https://en.wikipedia.org/wiki/Supercapacitor https://en.wikipedia.org/wiki/Supercapacitor EDIT: I'm not trying to inject bad feelings here or contradict Ohm. I'm just clarifying the effect of temperature on supercap life. There is some effect on cap lifetime at high temps. I hope the product succeeds. I know sailors have using lithium batteries for a while now, but as mentioned elsewhere, they are shockingly expensive (like $6k).

- conjecTech 11y agoThanks for the comment. It is something we need to look into a bit more. Generally we haven't seen the capacitors be the limiting factor in lifetime, but they might be in extremely hot situations. I'll do some more work on getting a definite answer here so we can be more careful/specific about our claims in the future.
