joseluisgzz the component you are pointing to is reference designator L7130 and it is a PIME103T-4R7MS 4.7UH 20% 8.5A inductor. The max current for this is 8.5A so it is possible that it is heating up due to overcurrent. I'd be checking Q7130 (component just above L7130) MOSFET. Get the datasheet for that from here. Of course you can always check L7130 with a multimeter (simple go-no go) as well as an oscilloscope. Check on here for an idea. I'd check mouser.com as well as digikey.com as well as many others for a replacement if you really need it.

First of all thanks for your answer. I already ordered the inductors just in case I need them. The data sheet link is broken. Could you point me what mosfet is the one I need. I know you said Q7130 and I'm looking all over the web, but I think this is the "label" on apple schematics, but I don't have schematics. Thanks
Q7130 is a RJK03P0DPA which is a 30V 20A 7.0 mOhm power Mosfet
Thanks a lot, I will update as soon as I receive the parts.
I received the inductor today , but the resistance is 20mohm, would it work??

That's a choke for power delivery, presumably for the battery (whose connector is right next to it).
If you're comfortable with soldering, you can try replacing the choke with an IDENTICAL choke; make sure you get the right one.
If you're not comfortable, then the only solution that I can think of would be a main logic board replacement. I don't think it's a problem with the battery, but rather the power delivery to and from the battery.

Thanks a lot, I think I've got the skills to solder the choke. Do you have any idea where could I get one? Maybe search for a damaged logic board that has one?
That's one option; you could try looking for the model # on eBay, Amazon (although I'm not sure how much luck you'd have with that). Good luck on your repair!
I got same issue. I ordered this: https://es.aliexpress.com/item/329004020...
and after replacement my mac came back from death. Thanks for your comments!
