The thermal fuse you found on Aliexpress, even if not identical to the original, can fit the same and 10A is sufficient for your application.
On the other hand, the type of NTC thermistor you have chosen is not the right one: you have to look for the type as shown in the attached photo. (The spherical body is very small)
The characteristics are given by the color code present on the body of the thermistor itself, unfortunately the only photo I found is not sufficiently defined to be able to obtain certain data, at least I can't.
P.S. what wasedadoc told you is right: Only the spot welder is used for batteries.
