battery question

[tropic420]

My electronics is really old 20 yrs but can you put 2 batteries in series parallel or do you need 3. I know its basic but I just cant remember I guess Alzheimer's is setting in

Not real clear on what your asking Tropic.... Can you explain what your wanting to accomplish?

You can put as many batteries in parallel or series as you like.

In series you increase the voltage with each battery you add...capacity remains the same.
2 1.5v 900aH batteries in series = 3.0v 900aH
3 1.5v 900aH batteries in series = 4.5v 900aH
4 1.5v 900aH batteries in series = 6.0v 900aH



In parallel you increase the capacity with each battery you add...voltage remains the same.
2 1.5v 900aH batteries in parallel = 1.5v 1800aH
3 1.5v 900aH batteries in parallel = 1.5v 2700aH
4 1.5v 900aH batteries in parallel = 1.5v 3600aH

I was wondering because. What if you made a holder or something that put 2 batteries in series parallel wouldn't that increase the voltage and amperage or do you need 3 batts for that?

Batteries in series will never increase amperage. The amperage remains the same/constant, only the voltage will increase. If you put 2 batts in parallel, voltage would remain the same and amperage would increase.

Tropic, your "Series Parallel" Statement is like saying "Turn Left Right" when giving someone driving directions... Series and pararllel are two different circuits...

Here is a link that may help as a refresher... wiring diagrams comparing the two circuits you mentioned... 94 Battery Wiring Diagrams

Hope that helps,

what i am saying is say you have 4 batts 5v 1amp. you then pair up 2 batts in series to give you 2 pairs of series batteries to give you 10v. Then you put those 2 pairs in parallel which gives you 2amps so you would have a series parallel circuit which gives 10v and 2 amps. Huh, I just answered my own question you cant put 2 batts in series parallel because if did they would just be in parallel. sorry for the confusion, the mind is a strange place

yup ... pretty much Sometimes its easier to diagnose when put on paper.

LOL Tropic Yes it is.

Glad you were able to answer your questions
