hi tx for the image

what do these 2 do?

the second is a special container for 18650 right?

It's a cell. Like an 18650 flashlight cell, but 25Ah. You don't have to weld it, because it has terminals that you can clamp to directly.

Maybe you should do some reading.

i search Threaded posts but there are so many thing with that name. would you have link of such battery specs and price plz?
why ebike people dont use them as much as 18650? do you know?

Lack of imagination? Herd mentality? Automotive cells didn't become available to hobbyists until after flashlight cells?

All I know is that big cells with obvious ways to attach to them are much easier.

Panasonic PHEV2

But there are plenty of other choices that aren't small enough to fit in a personal vibrator.

The last ones I got were from a Mercedes Benz, in a 12S module that only needed power leads and balance wires attached.
