pop quiz

just to see the differant opinions out there

1 12v battery
1 16v battery

ran in a system wich one will perform the best???????????

the amp doest matter, but say pulling a 700 amp load

12v.......

my bad state your reasoning

The amperage is better on 12v..

12V. My reason is because you said so. I believe you said it was because the plates in a 16 volt battery are thinner than a 12 volts plates so they can fit more cells into a battery of the same size. By having thinner plates it can't flow as much current as a 12 volt. Amperage is more important than voltage. although you still need to have voltage

12v batts have 6 2v cells 16v batts have 8 2v cells your correct bo

DAMN JEFF ANYMORE COOL INFO LIKE THAT MAN WE CAN HAVE CASUE I WAS GONNA SAY 16V

What should we look for as far as esr on a battery when looking I've heard different things?

12v will do better

on limited batts 12v will work better

call me dumb oh fearless leader but what is a esr on a batt.

Are you asking what is esr or what is esr on a battery?
esr stands for equivalent series resistance. Most battery companies don't include esr ratings. I know that Kinetik does. But, I don't recall the numbers.

I guess I'm dumb too cuz I was bout 2 ask that 2 dave...lol

Jeff,

I understand your reasoning based on the available products on the market. if the batteries had equivalent amp-hr ratings the 16 volt would win out. However, as stated, with current technologies for car batteries(excluding the new lithium batteries for electric cars) size vs. size the 12 volt battery can have significantly higher amp-hr ratings.

For example, lets say we have an amplifier making 8000 watts at 90% efficiency. We will need to supply the amp with 8000/0.9=8888.88 watts of power. At 16 volts we need 8888.88/16= 555.55 amps, whereas at 12 volts we need 8888.88/12=749.74 amps of current to make the same power.

My point being, the 16 volt batteries that are the same size as a 12 volt battery will have less amp-hr rating and current supply capability than the 12 volt due to the things discussed above. However at higher voltage inputs, you need less current to make the same power. A properly designed electrical system is another key component of a winning installation. I just didn't want people to misunderstand what Jeff was saying here and think that 12 volt systems are better than 16 volt, there are more parameters involved than just the potential across the terminals of a battery.

im with matt on this on.

amp-hr and discharge rate will really come into play when u limit to 1 batt. if a sickeningly high amp-hour 16v batt with a very low esr was availiable...16v it would be


by the way...if u can find one, i'll take 20

Similiar to ohms of a sub. Lower esr quicker discharge.

umm matt you have to know i already knew what you just said lol, and i was making a thread that would bring out facts to enlighten those that dont know

there is not a reat 16v battery thats why we always had to run a Dung Pile load of them to get our systems to here optimal potential

I know you knew this already, but the way the information was presented could confuse others. I was reinstating what you were saying with some more info I personally preferred the 8 volt batteries in series over the 16 volt batts if you had the space.

dude i gave them the food i wasnt going to spoon feed it to them also

Good topic.

Come on Jeff, they want to be spoon fed.

We are always considering new products for new applications. Since our 2009 model D1000, and new 2010 model D1600 are by for the most powerful 16V models available, why would we need an even more powerful 16V? If there is enough volume to justify the development of a new model, we would be happy to consider it.

a 16v battery needed to be good enough to only run about 4-6 of them to support the number of amps in the larger classes will take them past the 800sqi rule due to the thickness of the plates needed

scottie is correct the demand wont justify the need
