Anyone replaced the under-seat battery with this 150AH KS-Energy Lithium?

This is all very clever BUT have you informed your Insurance Company of these modifications away from the Factory Specifications on which your Insurance Policy is based?
They may not mind, increase the premium or refuse cover.
In the event of an accident you have given them the perfect excuse to refuse to cover repair costs etc:.

Winter tyres/cross climate would be considered modifications away from the Factory Specifications. I doubt anyone considers or cares about informing that change/modification nor an 80 amp AGM instead of a 75amp. There are a lot of fears around lithium that are unfounded. Don’t take this to mean I don’t agree or disagree with the statement above. Just levelling it out a bit.

All Season tyres are a factory option and probably winter tyres on the Continent.
Similar battery technologies probably not a problem, but battery cost/value is different with different battery technologies.

I already have many non factory stuff like solar panels on the roof, wrong wheelsize for winter, non vw brake parts and suspension etc etc.
To me the most secure place inside the van for a heavy battery is behind the bench clamped down to the rails. What about all bluetti and jackery power banks people have in their vans, at best strapped down? In a crash they will be a dangerous projectile. In my case the batteries will sit so they are unable to move at all.

The stuff some people write is amazing. The logic of a child!
If you think a garage fitting Michelin Cross Climate tyres is equivalent to you doing a DIY fitting of some Lithium batteries you bought on the internet I worry.
But don’t let me stop you. Knock yourself out. A brave decision, as they say.
