[QUOTE="Thnking, post: 2441333, member: 571105"] LOL, oh really…and what exactly is the capacitance value in proportion to surface charge. Give me a break, 1V…LOL. Even with 20’, the resistance is going to be under .002ohm. 1V=I*.002 That’s 500A, which also is well above any recommended ampacity for the 1/0 wire. There’s nothing wrong with relocating the battery, but it’s not going to have any significant effect on Vdrops along the line. I never said resistance is negligible, I said resistance in wiring should be properly matched to load to minimize opposition to current. Once that is done resistance isn’t significant. Competitors use batteries based on completely different reasoning. Banks of batteries are easier to install and provide very large amounts of current for short durations. 1 battery may be able to discharge 400A for a sec over 2V potential. But that in 2 banks of 4 batteries, and we have very large capacity. Trying the same thing with an alternator is much different. Alternators increase current output, to begin with, with an increase of mechanical energy. They also are regulated to produce variable fields. Those make them difficult to properly adjust for purely a competitive standpoint. They also, aren’t made regularly to provide as much current as a large battery. And 4 alternators don’t fit under any hood I’ve ever seen. Only if the dimming is very bad, or voltage drops are very large…in which case the alternator isn’t large enough to begin with. Wiring and source (alternator) should be matched to the load, period. [/QUOTE]
