A friend brought his fresh-from-ebay macbook pro A2141 after he failed replacement keyboard plugging.
I fixed all the little problems he introduced.
I am unable to install macOS to this device. Both Sequoia and Catalina (from Internet Recovery) start to install, but after ~2-5 minutes into the installation the macbook does a hard restart (max fan spin for a split second, then reboot without chime).
I noticed what I think is a very high power consumption, like 20V/1.7A when activating WiFi for internet recovery, and more like 20V/3.7-4.1A while downloading the recovery...

From disk utility I deleted all partitions ( there was boot camp and macintosh ), created GUID Partition Map / APFS and I'm trying to install High Sierra from USB and its failing in half way, if I use Internet Recovery I have error apple.com/support -5101F, its shows me the option to go under support and mentions that battery have to be replaced.

I am hoping that someone more knowledgeable than me in the area of understanding installation logs, or someone that has had a similar issue in the past may have some ideas of what might be causing this.
The issue:
Unable to do a clean install of any macOS versions supported for this model, even after fully erasing and formatting the internal SSD,... -
