Is that expected to be sufficient? Typical automotive electrical components are rated over -40C to 85 or 105C. I think the engine compartment is typically hotter than 50C when a car is running. This might be more suitable to a car that mounts the battery remotely: I have seen BMWs with the battery in the trunk.

We're being conservative with the temperature rating for now. The components are rated better than that, but we're still running cycle tests in our temp chamber and waiting to get the system tested by an outside lab.

It's not sufficient in Canada. We regularly see temperatures below 30 C. Hopefully they can push it lower, because a battery that quits when it's cold out is pretty much worthless up here.
