very much with you and GP on this. the route I personally take is to learn with small trials and error of what comments and advise is good and what is silly or outright dangerous. Places I frequent for such advise though aren't YT videos but forums where it's easy for others to call out silly ideas (which isn't always the case on YT). YT is at best a gateway to deeper content such as explosion-charts, repair and maintenance manuals, etc. I think batteries here are not too different than breaks, steering or suspension (all components I've grown comfortable to touch although not on my very first DYI project but years into messing and learning about the same vehicle).
