I guess I am old school. But I still carry a portable lead acid battery jump starter in my vehicles mainly because the inside temperatures in the vehicles can reach 120 degrees F, which is outside the upper temp range of the Lithium jump starter packs. This is mainly a concern if I am going on trips and have to leave my vehicle out in the open for days on end.
.
Am I missing something or are there Lithium packs that can support higher temperatures (120+ F)? If so, I’d prefer to switch to them.

Apparently , yes.
I don't know where you're looking.
Every NOCO booster I checked (GB150, GBX45, ...) on their website ( https://no.co/), shows operating temps up to 50C (122F)
The even have "ultrasafe" models with some additional thermal management. i.e. GBX55
Wow, shoot, I stand corrected. 122 degrees F for operating temperature, you are right. I don’t know how I missed that. I know years ago I had looked for portable Lithium chargers and they were all less than 120 degrees F; I guess they improved on the design.
.
Since 122 F is the upper operating temperature, can we assume the storage temperature is even higher?
.
Also, any chance leaving Lithium charger in a vehicle can catch on fire?
the chance is always non-zero. So is getting struck by lightning but we never think about it.
Noco is a very popular brand. I don't think people would be buying it if it was setting fire to a lot of cars.
Ideal storage temp is 60F. Keep it as close to that as possible.
The cheap one that Scotty recommends has an operating range of -30°C to +50°C
Lead acid batteries suffer in high temps much more than lithium ion batteries do.
All the Lithium packs I see are rated for up to 113F. What happens to them at 120+? Will my vehicle catch on fire?
.
I trust the lead acid more in heat due to using lead acid in our car batteries.
Lithium-Iron-Phosphate (LiFePO4 or LFP) batteries are safer at high temperatures, but they self-discharge faster, and energy density (capacity) is lower than the more common Lithium ion chemistry (Li-Cobalt)

So, what should I do? I am concerned about the Lithium packs catching on fire if I leave in my vehicle, especially at the higher temps. Do I wait for LFP packs to come out?
they're already here

I can't tell you if they're any good

Same chance as leaving your phone in a hot car I suppose.

Why not do some research to see how common incidents of spontaneous combustion are with lithium jump starters? I've read of incidents where cheap, poorly-designed ones will short out or overheat when used and catch on fire. However I have no idea how often even leading brand jump starters might catch fire just being stored in a hot car.
