Voltage?

[Gnab2 10+ year member]

I see that 14.4V is a common rating and most batteries deliver 12.5V. How can I step the volts up to 14.4V or 17+V?

you can get 14.4v getting a new and bigger alternator... lets say like 200amps-250amps

but 17v on the other hand is almost impossible for a "normal setup"

I just ordered a 220A from Excessive, should I be expecting 14.4v? Will I need a deep cycle battery to achieve this?

220Amp alt should get you to at least to 14v with a regular battery but if you can get a good batery you'll get more voltage

My stock system is running a little over 14.4

You can get 13.8V - 14.4V by turning on your car (depends on make)

battery, battery banks, adjustable voltage regulator, second alt ......................

I was thinking a 24 Volt Catapillar battery to see if it would work. Will this back-feed into my current system? And will it due damage that really SUX?

No amplifier that I am aware of can handle 24V, you'll smoke just about every one of them.

Along with that, if you ran that battery to your vehicle's electrical system, you'd fry every electrical component in the car.

You'll get more resistance to voltage drops, but hopefully not more voltage...anything much over 15V for a 12VDC battery could start a thermal runaway situation //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I can run two of the 24 volts in series to get a long run deep cranking 12 volts, True? Plus this would not get into the thermal issue and would charge right? I know that there is some great after market batteries out there but I have these one hand. Now will a voltage regulator block return voltage?

Most batteries are 12VDC batteries, but have you not noticed that when you turn your vehicle on you receive around 14? Most batteries, without pressure will provid 14.4V to the vehicles electronic components.

Wrong. Two 24V batteries in series will have a combined voltage of 48V...you're confusing it with wiring in parallel, which leaves voltage constant but increases the Ah.

There's no way to get 12VDC with 24V batteries.

SORRY it has been a real long day and I have not been thinking to clear here lately. I am just looking to get the most from my amps. Most of the amps are not rated at a true 12.5 volts. I am looking at pushing things to the limit and then some. I here mixed reviews on using Caps. I have used them in the past and see some improvement but I want more. Thanks Everyone.

get an alternator that put out a good 50 amps more than what you decide your entire electrical system needs. I got mine from mr. alternator and originally i would be at 14.4 at idle with nothing on and 13.9-14.0 with my vent blower and electric fans on. With the new 200A alt i sit at 14.7 as idle and 14.3-14.4 with the vent blower, elec fans and radio on.
