[QUOTE="Doxquzme, post: 8924115, member: 689267"] It's not unequivocal; it's conditional - not everyone, actually, 95% of the people setting up 2k systems are EVER going to need an upgraded alternator, that's a fact, not an opinion. LifePo4 and Lithium options not only store enough reserve ( and replensish it quickly when not needed), but they will also deliver a burst at much faster rates than a flooded or AGM can, not as fast as a cap, but your 5 farad capacitor, with little to no reserve (and one reason to actually have an HO alt) well, it's tapped out long before a similarly priced LifePo4 battery, not even close. One has to take into account the balance between the various options, and what works best, which is to say, one is not more "correct" or "incorrect" than the other. There are considerations with upgrading an alternator, such as different pulley sizes, belt sizes, reduced mileage, and reduced power. In a Mustang GT, you're not going to notice, so there is that. It's a far more difficult option, almost impossible in some newer cars, not so much in older ones, due to various electrical functions that are tied to the way it operates. Additionally, not everyone can get under the hood and change out an alternator, and while I'm fully capable of such, it's locatioin makes it a real PITA for some. All these options are viable; one is not better than the other, unless the system demands it, and then it's likely going to be a combination of both HO alt and lithium support. In the 2-3k wattage systems, new battery tech provides an absolutely viable option, an option, and in my experience, that is an easier and often less costly and less labor-intensive option as well.
