I fail.
Say you're drawing 300A. Which is what a good 5k would draw on music. 300A X 12.6v = 3,780w assuming 100% effeciency. Now step that up to 14.4v. 300 x 14.4 = 4,320.u will gain a lot more then a few extra watts when alt is charging at 14.4-14.5 compared to 12.6.If u need help I'll guide you through it.
That's a grand total of 540w. 500w on top of 3,800 is MAYBE 3-4 tenths. Worth it when you're making your alt work 100% load all the time?
Not for me.
And that's IF you had a 300A alt.
