I would say like any product, use it the way you need to use it. These things are overbuilt to be idiot-proof, 100% isn’t really 100%. It’s only on niche spaces like Reddit that we freak out about never charging more than 80% or whatever. Most people are treating these like gas cars and charging them up to 100. Will the life of the car be shorter? Maybe a little. Probably not much. I bet you lose 5 more miles of net range after 5 years or something small like that. But your car’s life will be a lot shorter if you have to sell it now rather than use it.

I drive a bolt and have taken 350 spots before, mainly when the only 150 spot was also the only Chademo spot and there were other 350 spots available at the time. My rationale was I was blocking a more scarce resource at the slower charger by screwing over leaf drivers. Not sure if that applies to you.
