[QUOTE="wew lad, post: 8667444, member: 665412"] 5000a at what voltage drop? it's marketing wank. Batteries have fairly high internal resistance. You could get away with 1 bank of caps and a HO alternator because the internal resistance of the caps is much lower. With a crescendo 4k wired at 1 ohm your current draw isn't going to be even 1/10th of 5000a so it makes no difference. There's basically two classes of "good" batteries. 1) Trusted manufacturers like East Penn who produce duracell and other AGM's 2) Premium manufacturers who offer higher purity lead like Northstar, XS Power, and Enersys. The cost/benefit for the premium isn't worth it, you'd be better off buying a bank of supercaps or more East Penn batteries or LTO cells The cheapest batteries you can get are not the same as trusted manufacturers batteries. Optima is about as low as it gets these days. [/QUOTE]
