Wiring Batteries in Series and Parallel.m4v

Correct and remember with parallel to keep wire lengths the same. If you have uneven lengths the shorter set with lower resistance takes the bulk of the work cause heat issues. Especially important on low voltage high amperage DC circuits. Very important.

Is there a way it can be all connected that I will still get my 48volts with 21Amh ?, then will that be harmless for my e-bike which should be just 48volts 20Amh ? Thanks.💞

Bunmi Ajibola Instead of each battery being 12v they’d have to be 24v.. Pair of 24v batts = 48v Add another pair, wire in parallel and then you increase amps and runtimes

I had same question. In Parallel, Pos1 to Pos 2 to inverter/motor positive. Neg2 to Neg 1 to inverter/motor negative. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-C63I8VT6CHo.html

First and last Batteries

BS.

Hahaha

is this true or are you trying to burn someones equipment?

@@camit6237 it is true + to + and - to - keeps at 12v is how semi trucks run on with 4 batterys.

No it’s correct information. Look it up on a different site if you don’t trust the video. I will tell you this: any different answer than the one found here is wrong. Retired 36-year electrician.

Shit I have 14 batteries in parallel. With 6 100w panels. It's been 5 years with no problems.

It is painful answer has not been provided for this your question, that would have been a great help for my planned 48volts 20Amh battery now.

According to my research ....the bet way to change for more than 2 is to arrange in series

@@frankfrankmusyoka8050 I've got an old 24v bus that I'm doing up ... retaining the 24v system including HUGE inverter. My solar controller is auto selective 12/24v & Im using 4 household sized solar panels & 4 truck batteries, wired in parrallel. No good using deep cycle batteries because I require the crank amperage! Truck maintains charge when rolling. Generator for emergencies only. So I'm 240v constantly (inside) & 24v for the mechanics.

Just like charging a golf cart. All at once.

As per my knowledge you no need to charge separately ,do it all together

Sounds like your batteries will never reach the voltage required for the car unless it's like a 7volt car.

approx. 24 V cause 24V || 24V = 24 V.

+sharikosatia because he isn't completing the circuit on any or all of the batteries. 1- to 2+ is just a link, had he also done 2- to 1+ then the circuit would be complete and with nothing to take the load it would be a short.

Yes you can charge them with 24v supply too....

If you are trying to run multiple ups. Off one battery i would put a switch on the positive cables of each ups to prevent conflict during charge basically keep one on and the others off then when power goes out simply flip the switches and unplug the others from the wall incase power comes back. But you will lose battery power allot quicker . i have an ups connected to my security system and a 12v battery to run 12v 16w l.e.d spot lights

I wonder if there is a device on the market that will let you do it automatically?

Solar charger with an inverter may be a better less sophisticated option for you . you can get solar panels and a charge controller relatively cheap

Great real-life question; unfortunately, I don’t know the answer.

Get an 24v inverter... Or in an emergency you can disconnect one battery so you get 12v.

+Jessica Chon Just gotta duplicate the process over and over till you reach the voltage or amps you want. It's the same no matter how many batteries you use. Just gotta use thicker wire the higher you go.

King, this man is 100% correct. I spent 30-years as an aviation electrician and I learned the same way. Also, when electrical things “fry” typically it’s from someone not being familiar with electricity, in too deep for their experience level, of flat out a person that shouldn’t be allowed to purchase tools. If you have proper training and experience working around electricity makes sense and you damn sure respect it! If you don’t know codes or aren’t sure call a qualified electrician. His rate is dirt cheap compared to rebuilding your burnt down home. See it too many times.....

Parallel is pos to pos and neg to neg. Series is neg of first to pos of second, neg of second to pos of third, neg of third to pos of fourth. And just to be clear when hooking them up to whatever you want to hook up to. The pos of battery one is your positive hookup. The negative of battery four is your negative hookup. You never ever want to let the positive and negative terminals of a battery contact each other through an accidental wire touch or if the ass end of the wrench you are using to tighten one terminal comes in contact with the other terminal. I did that once when I was a teenager. Wrench went through my terminal as if it were mash potatoes.

Do volts or amps kill you? So, back to which kills you, the amps or volts. Given your body is a constant resistance, it really is a combination of both. Higher voltage means higher amperage, and thus higher voltage has more potential to kill. It takes only 100mA to stop your heart. Dec 29, 2003 ~> 2020/20/06

If one battery capacity is 12 volt. we can use two 12 volt battery. connection +- =24 volt. we can see other two terminals show 24 volt.it is called series connection . I am Bangladesh. welcome for comment. I hope you replied me

Linking them in series doubles the voltage, 12, 24, 36, 48 ect. Linking parallel doubles the amps, 18, 36, 54, 72 ect. So 2 in series is 24V at 18A, Hook up 2 in parallel to that and it will be 24V at 36A. (2S2P) Series is Voltage, Parallel is Amps.

Exactly thats my question too
