Hair clippers are probably a good example of something where you’d want to replace the batteries and not just remove them.
Lithium ion batteries are typically rated to discharge at 2-4 times their capacity. So a 2.5Ah cell is rated for 20 amps, but if you run into something tough it will easily deliver far more amps than that.
Those cells look like they’re wired in series so they’d want 8V at potentially 20+ amps which is not a small amount of power to run some wires to.
Without prior experience I would not mess with anything with a lithium ion cell.
Linus Tech tips actually had a video on this recently where he removed the batteries from many small electronics in his house and showed how to power without batteries. Not sure what it was called but was probablyike 6 months ago

This one? https://www.youtube.com/watch?v=bTpKM43VhwA
It’s a good video but for powering simple removable battery devices. It’s different for ones that have cells and charging/protection circuitry.
Thanks, I found the link, i’ll see what I cando with that !
