No, it is the chargers.
I will repeat one more final time: The Porsche Charger is garbage.
This opinion is shared by many. Feel free to read up on this in numerous threads regarding the subject.

I think the charge clamps logo is there just because they don't want anyone treating it like a normal AGM/Lead acid battery. It's a LFP battery that shouldn't just be hooked up to normal 12V AGM batteries to jump start or something. But if you are using LFP compatible / li-ion compatible chargers and equipment, there's nothing wrong with connecting to the terminals directly.
