Wiring Batteries in Series and Parallel.m4v

This video demonstrates how to wire batteries in series and in parallel. Series means connecting a negative terminal of one battery to the positive terminal of another battery to increase the Voltage . A Parallel connection on the other hand, means connecting "like" (Positive to Positive and Negative to Negative) terminals of batteries together. This does not increase the voltage, but it doubles the Amp-Rating or Runtime. The video demonstrates how to get 24 and 36 volts from a series of 12 Volt batteries.

Hi,I'm sorry I didn't get back to you sooner,we went camping in Maine.I plugged the fridge into a killawatt,on startup it uses .93 amp and 83 watts.The marine battery has 675 marine cranking amps,105 amps,and 182 minutes reserve capacity.On the frig the only reference to amps is 1.4 amp input current.Thank you MrDavey,this will be a great help to my family.Rob

[@dsdsmitty2]

Exactly the thing I was looking for and it was great that it was no longer than five minutes! Thank you, thank you!!!!!

[@ChicharonyPresidente]

Yes, you can. You can do the two 12 volts in series. You do need to keep in mind the amps you are drawing and the capacity of the batteries for your application. Two batteries in series will double the voltage but will keep the same amp hour capacity.

[@GeraldPUR]

This video has aged well! Thanks!

[@umxrr8677]

This is what i have learned: Connecting in series : increase volts but same amperes Connecting in Parallel : increase amperes and same volts

[@mds1986ms]

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.

[@artjiblaframes.7190]

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.💞

[@skywalker859]

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

[@gregg2742]

yes you can wire 4 12v in parallel and increase the amp capacity the volts stay the same .. in series the volts add up 12-24-36-46>> the rc( reserve capacity also climbs ) so a series 3x12=36 rc per battery is say 140 you have 3 batteries in series then you have 720min

[@twilightprod]

The terminals in the video are M6 (They take a 6 mm metric bolt) They came with the batteries. The NB Terminals on your batteries require a small nut and bolt which should come with the batteries, and a ring terminal. Secure the ring terminal to your wire and thread the bolt through the holes in the NB terminal and ring. I hope that helps.

Thanks for this simple and informative video. I do have a couple questions that aren't really addressed in these type of tutorials for the series-parallel configuration. Firstly, from which terminals should I connect a charge controller and/or an inverter? And second, can DC circuit breakers be used in place of fuses to protect the batteries in a LiFePO4 battery bank? If anyone can help clear this up for me I'd greatly appreciate it.

[@ChicharonyPresidente]

Small in size but powerful in nature is what the ideal battery would be. Look for batteries that have the amp hour rating to suit your needs. The more amp hour a battery is rated for the longer it would last. All other items kept equal. Solar power applications are best suited for the "deep cycle" type batteries.

[@oilbay54]

As you see the voltage of the battery pack on the right was 25.4Volts and that of the left pack was 25 Volts. When connected in parallel the overall voltage became 25.2 Volts. So where did this 0.2V go? Simple, it discharged on the second battery. So if you don't have to, do not connect the batteries in parallel since no two batteries are identical. The one(s) with higher voltage discharges on the lower ones and this shortens the battery life. I think the batteries in this demo are 18AH. The price of these batteries are nearly 30 USD. The 36AH batteries are sold for 55 USD. So it is cheaper to use one battery. Note: I think these batteries are very old and discharged. The fully charged battery voltage is 13.6 Volts for this type of batteries

[@Philiam1973]

Thanks for the demo. I've been trying to find a video for this. Is it possible to link 3-4 12v batteries together and keep the voltage at 12v so I can use a 12v automotive type AC power converter?

[@juniorizq2342]

Im sure that if you bring the voltage up it brings the amps down vice versa which is why semis use 12v system. Because the starter draw alot of amps

[@StephenTrenewablenergy]

That makes it easy for people to understand.

[@rich1051414]

Lots of confusion below. Although there is a saying, volts dont kill, amps do, that is only partially true. The reason he is able to touch the two terminals without a shock is because the voltage is too low to overcome the resistance of the body enough to complete the circuit. If he had wet hands, he would have felt it... and we would have known it. Basically, don't try it at home. As you put more and more in series you are making it more and more dangerous. A single battery has enough amps to kill you, but the higher the voltage, the more likely you are to be shocked via your bare hands, or through insulated handles/gloves. The amps do kill you, but the higher the voltage, the easier it is for it to bite you. Converting to AC makes it even worse, because how the current alternates, shocking you in short bursts over and over again, typically around 50-60 times a second. Sure fire way to kill a heart.

[@Xxxcappie23]

great vid, what would the voltage be in the last configuration with series and parallel between the positive and negative when connected . Will it stay 24v or will it be more?

[@adigrimlock]

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

[@ChicharonyPresidente]

There are some gaps in your question. How many volts is the panel putting out? You want to match the volts that your panel is rated for to the volts of the batteries. In a car, the alternator charges a 12 volt battery at about 14.4 volts or so. you need to match the panel's voltage to the battery or batteries voltage in the same manner. Too little and it will not fully charge, too much and you can damage the battery.

[@robviolin1]

Thank you very much. It helps a lot . Keep making electric vids.

[@greasyamado]

Excellent video and to connect 8? A 24v increasing amperage would be the same?

[@davidjames9935]

A few comments: Doubling the Ah rating of a battery bank does not double the runtime. The runtime of a constant "reasonable" load of 4 of your batteries (24V) verses 2 of your batteries (also 24V) should be about 220% runtime, not 200% runtime. This is because the 4 battery bank "sees" a relatively lighter load. Another example is your 12V 18Ah batteries are probably rated at the 20 Hr drain rate. However, at the 40 Hr drain rate, they are probably rated at 20Ah since that would require a lighter load. So my point being that the Ah rating of a battery is not a constant, but rather a function of the load on it. The industry standard is using the 20 hour drain rate which may or may not be representative of what it will be used for. For example, in a golf cart, the 20 hour drain rate specification is not very useful since the cart will not last 20 hours when used. A more accurate number for that application would be the 2 hour drain rate so a golf cart battery rated at 210Ah for example (20 hour drain rate) might only be half of that at the 2 hour drain rate ( 105Ah equivalent). Also, for jumpers, it would be better to have a "neutral" color like yellow or white to indicate they are jumpers and not wires that need to go strictly to negative or positive. It makes a series/parallel setup easier to look at and understand quickly.

[@Asadullah21]

+David James Please help me understand. So there are 2 ways to connect batteries. 1. IN SERIES: only increases voltage. 2. IN PARALLEL: Increases Amps and Voltage at the same time. is this correct? thank you!

2. IN PARALLEL: only increases voltage .

[@davidjames9935]

***** Well it depends. If you connect a 6V battery in parallel with an 8V battery then what would it mean the voltage stays the same? Same as what/which? It depends on many things including load, where you check the voltage at, the state of charge , how the batteries are connected.... Also, there is such a thing as series/parallel (combination) hookup. For example, if you had four identical 12V 150Ah batteries, you could wire them in series/parallel for 24V 300Ah. I used to do that when I had those batteries and also had a 24V 36A (max) charger. Worked well.

[@abbason5064]

maybe you can help me out , I use a electric wheelchair that calls for 12v sealed acid battery am I able to add a 6v sealed acid battery and push 18v my moters?

[@davidjames9935]

Yahshua Worshipper - Are you sure it is only 12V required? If you are sure, I would try 14V first to see if there is any difference. You would then likely have to use a different charger. I have used a 6V and an 8V battery is series for 14V for projects and it works well but I have a special charger for it since a 12V charger will not work on a 14V bank. The charger will either already think the bank is fully charged (when it is really not), or it will stop the charge prematurely which is bad for the batteries. However, there are easy ways to charge a 14V battery bank. What is your goal with more voltage? Do you want the wheelchair to go faster?

[@oafyvonskidmark316]

Series circuits the "loads" are wired "nose to tail" as circus elephants, in single file. Parallel circuits the loads are wired like rungs on a ladder with the ladders rails being the 2 sides or "legs" of power. The same thing goes for batteries, Two 6 volt batteries in "series" = 12 volts, that is wired Pos to Neg to Pos to Neg like circus elephants in single file connected nose to tail to nose to tail. Two 6 volt batteries in parallel = 6 volts , that is wired like ladder rungs with the 2 legs or sides of power being the ladders side rails.

Connect a jumper wire from battery1 P+ to battery2 N- Connect your appliance to battery1 N- and battery2 P+ This will give you 2 x 12v = 24v For a SERIES array, each terminal can only have ONE CONNECTION. If there is more than one connection per terminal, you have done something wrong.
