How/why is it that two batteries with the same voltage may preform at different levels of power based on their amp hours? For instance, a 2Ah battery powering a weed eater at full charge, and the weed eater not working as powerfully as it would with a fully charged 4Ah battery?
Forgive me, I’m new to hobbies involving power tools but I’m excited to learn!

The 2Ah rating means the battery should be able to provide 2 amps of current for 1 hour.
An extra rating of a battery is the C rating.
The C rating multiplied by the Ah rating tells us the maximum current the battery can constantly provide.
Eg:
* 2Ah battery with C rating of 10 could provide 20amps
* 4Ah battery with the same C rating of 10 could provide 40amps
