Should I trade my P15 Gen 1 for a P1 Gen 2 + cash?

Title. I received an offer to trade my P15 Gen 1 (i7-10750H + Quadro T2000 + FullHD LCD 500nits + 90% battery health (<100 cycles)) for a P1 Gen 2 (i7-9850H + Quadro T1000 + 4k Oled Display + 70% battery health (+-250 cycles)) + 200 dollars back. RAM and Storage are the same.

I am currently building a desktop PC so I dont need that much power, and I would like the portability. I would get the P1 and immediately order a new battery from AliExpress + repaste with PTM7950 and Upsiren Pro.

There is anything I should be worried about it? Some chronical problem, damage, hinge situation, performance issue, etc.
