Hello,

In the next few months, I will have to rebuild 2 ebike Li-Ion battery packs.

Which point welder is recommended for a reasonable price that I can pay with this 2 battery packs?

Something like the Kekk K7 Pro would likely be a good choice for you:

Otherwise, something slightly lower end like this new unit from Kekk also works:

The firmware is not as flexible, but it still works well.
