one on the big 3

Hi there, thank you for look my post!

i got a question on this setup.The question is that i know i have to run a cable from the alternator to the positive of the battery but i was wondering that the alternator will charge the battery without any restriction, can the battery be damage???

i dont know if that cable will bypass a voltage regulator or something... that's my fear.

Thank you for your help!!

No.
The voltages does not go THRU the regulator. The regulator senses the battery voltage and adjusts the alternator's output (by varying the rotor current - hence a small rotor current change effects a much bigger output - ie, output current by changing/regulating output voltage).

And, you cannot "force" current into something....
The battery might be a small size (say 10A not that that means anything in reality - it doesn't matter whether the alternator is 10A, 100A, or 100,000A - the battery will only take what it can take.
[It's based on voltage. The only way to force more current is to increase voltage, but 12V batteries handle a max of 14.4V. Anything above 14.4V (long-term) is overcharging and that will damage the battery.]
This does not mean batteries are subject to a maximum current - eg, a 10A battery may only like being charged at a max of 2A, but that's not an issue for normal vehicle systems. (It is - but nobody worries about it - very few if any vehicles systems employ current limiting. Nor do "smart battery systems" (dual-battery & isolators etc) despite what they appear to claim!)

Thank you very much!!!!
