Hello, with petrol with pretty much everyone. More difficult with gas, as pure propane is not sold in Switzerland, but 70% butane + 30% propane, butane does not like to gasify at sub-zero temperatures and remains in the bottle, i.e. after 30% propane is used up, it goes out.
In combination with batteries, it is also important to note that LiFePo4 must not be charged at low temperatures.
If you are interested, I have an unused petrol-only model on Tutti.
