Need help reseting system for new house batteries

[DrivingMissLazy]

the answer is 464 ah

gotta run

chris

It that answer of 464 amps from Heart? Is the the maximum setting of the Heart?

The capacity of the three strings is 696 amps at 12 volts. Something does not sound right.

OK....I called the manufacturer and they told me 696.

Thanks much guys

[Hartley]

Phil, you should set your amp hour capacity at 700 on the Link.

I don't know why Dave wants to do the division, but he's mistaken in this case.

If you look at the examples in your manual, you will be able to figure it out.

Enjoy your new house bank.

Maybe what I actually meant was correct, it didn't quite come out that way when typed. No I did actually mean 232 amp hours @12 volt.

For his 3 banks @ 12 volts the 696 ah rating would be correct.

[Hartley]

I have to believe that Dr. Dave and GMbusguy1 went to a different electrical/electronic school than I did. I would also have to believe that ideas such as theirs could have caused them a lot of problems in the past. LOL

Richard

No not really.
Was running low on Bud Light..wasn't paying attention...

Problem solved.

A lot of this confusion comes about solely because someone in the past incorrectly decided to use Ampere-hours as a measure of energy when in fact it is a meaningless unit.
As an example, if you say your pump draws 10 Amps so uses 240Ah per day if it ran all day, and I say my pump draws 5 Amps so will use 120Ah in one day, whose pump is more efficient? The answer is, there is no possible answer given that information.
It may have made a little sense when all batteries and systems were 12V but when there are 24V and 12V and now even 48V automotive systems, it just causes a lot of confusion.

Power is measured in Watts (=Volts x Amps), NOT Amps, and Energy is measured in Watt-seconds or more usually in domestic situations kilo-Watt-hours, NOT Amp-hours or Amp-seconds. Have a look at your electricity bill. A battery stores Energy so connect several batteries together and you add the individual energies together to get total stored energy.

A little reading to get up to speed on connecting batteries in series and parallel.

Six 232AH 6 volts hooked up as said will give 696AH at 12VDC or about 348AH (50%) usable to get good life out of the batts.

Now I am completely lost. How do those # add up?

[gus]

Amp-Hrs is not meaningless, it is a measure of reserve battery power (Capacity).

It is very important for deep-cycle batteries.

Its real value for start batteries is when your alternator fails or the engine takes longer than normal to start.

The primary measure of start batteries is Cold Cranking Amps, this tells you how well the battery will spin the starter.

A-H tells you how long it will keep up that spinning.

Bobsw....open "batterytender.com" link and find "SERIES / PARALLEL CONNECTIONS" & fig 4. Explain it very well.

So what is Don is saying "Six 232AH 6 volts hooked up as said (3pr or banks of 6v in series) will give 696AH at 12VDC (3 banks of 12v @ 232amps in parallel)

Hope it help if not please email me silverclip at aol dot com

FWIW

DR. Dave, Thank you for your explanation. I truly suspected that you had imbibed on a very bad batch of Bud Light. I even hesitated in replying to your post as I was questioning my opinion. 

I want to make clear to everyone that all or any of us can make a mistake. I have been following your posts for many years and I believe this was the first time that I have ever observed you making an error or mistake and I strongly recommend you get rid of the rest of that bad batch of brew, if you have not already done so. LOL

Richard

[H3Jim]

Dr Dave, I second DML's comments, your reputation made me question myself.

Send some of that brew over here, I need some after the day I had yesterday. )

[Hartley]

Actually I re-read what I said again.

In a way if you look into the calculation although it looks obviously wrong, the outcome is still correct. of 232amos@12 volts per bank. Then they are paralleled for 232 X 3 for the 696

It was a simple mistake of theoretically halving the available amps of each 232 amp battery to get to the 116 ... Then the 2 @ 116 = 232@12 volts

I simply ran out of beer that powered my calculator....

I had a brain fart and was figuring out some resistance values on something else that took a few complicated series-parallel values.

My next project is buildng a Flux capacitator and a Mr.Fusion to run my bus....

Write now its all confusion. Just because I can't explain it doesn't mean it wont work.... The Impossible we do immediately, The Difficult takes longer...

Thanks Guys,

Dave...

Two 232 ah @ 6v batteries wired in series provides 232 ah @12v.

Put 3 sets of these in parallel and you get 3 x 232ah = 696ah @ 12v.

That's what you should put into your meter so it knows how to manage the input and output amps.

[gmbusguy1]

Imagine that 2 brain farts in the same post on the MAK board hahahahah

who would a thought

LOL
Chris

at least I confess to mine  (this time at least)

[gumpy]

That last post was supposed to have been in good fun as it appeared several had run out of beer while posting their responses. After re-reading it, I think it may not have been taken as it was intended and for that I appologize to Chris and Dave. I'm going to
modify it....
