I work with lithium ion batteries, porsche, bentley and RR has had them for years now.
They are not hot swappable, meaning if you take a cayenne with a lithium pack battery (usd 1900 cost) and try to replace it with a plain or AGM (250 usd cost) because you cannot afford it, it wont work as the battery charging voltage, amps and decay life timer is completely different than any lead acid unit.
I understand that you love to use youtube as a āguideā but dont fall for it hook line and sinker! It can get very expensive very quickly. Do your own due diligence first before vouching for it. Chrisfix is in business of making youtube videos, not in business of auto repair,
There are lots of videos out there showing absolute asinine procedures for repairs (we in this trade literally laugh at those) - some jackwagons show how to replace the rear main seal on old I6 bmws and when it still leaks - they claim, bmws leak oil forever
While completely overlooking the fact that they never cleaned the oil seal carrier bolt threads and never bothered with thread sealer. š¤£
Such info isnt needed from a book for us in this industry but just a simple thin straw etc, if the hole isnt blind, it needs thread sealant or it will wick and leak. For us its basic common sense. Too bad youtube university doesnt teach that to āyoutubersā
