How to wire batteries in series or in parallel, and what the benefits and disadvantages are of each method. For more information about circuits wired in series or in parallel, please see our video discussing this in more detail. For the purpose of this video we want to show you has this applies to batteries.
When thinking about how to wire multiple batteries, there are a few things that we need to consider. First is what is the voltage requirement of our load.
Most batteries produce 12 volts DC. So, if our load requires more than 12 volts, this needs to be taken into consideration when wiring our system. This can also dictate how many batteries are needed in our system.
We also need to consider the capacity of our battery, or how long the battery will last. This is determined by the amp hour rating of the battery. Amp-hours is how we determine how long a battery will last running at 1 amp. For example, if we have a 20 amp-hour battery, that battery will power any load at 1 amp for 20 hours. Or, it will last for 10 hours, when the load is drawing 2 amps, or 1 hour at 20 amps. So depending on the amp-hour rating of our battery, as well as the amperage requirements of our load we can determine how long our battery can provide power.

In a parallel wiring situation run the negative wire going to the load from one battery and positive wire from the other battery to make the circuit use both batteries more equally and throughly.
Great course! Short, simple and to the point. Thank you.
You're welcome!
Thanks, and well done tutorial.
Had physics in high school and your video confirmed what I thought I remembered (it's been almost 45 years ago!).
Mr Buckholz - Kokomo High School (Indiana) - was a great teacher!!!!!
Made physics fun!
Wow! They had batteries 45 years ago!!! 😉
This is nothing to do with physics 😂😂😂
You could put the load (red) on the second battery and still be in parallel which would give you equal charging and discharging capabilities. It would also increase the battery life expectancy because it’s better balanced. Often the battery at the beginning of a parallel circuit does the majority of the work will the battery at the end does the least. Food for thought. Balance your load. =] LoL
I'm so confused! Lol!
@@saltycreole2673 it’s just a better example of wiring a 🔋 battery bank. You always want the flow to be balanced so the best over all wear and tear because batteries 🪫 last longer if the use is slow both charging and discharging with a wired balanced load. There are plenty of diagrams depicting how to wire batteries in a balanced wiring array for our batteries.
but what if i wire more than 2 batteries?
@@theuntitledgoose it all depends on what you need. If you want the same voltage but more amperage you go parallel. If you want more voltage and the same amperage you go in series. Yes you can mix the two if you have two batter banks in parallel and want to double your voltage. There are a lot of wire DIY videos here on CZcams. Heck on my other channels I have a “series” of them LoL 😂 🔋 I hope I have answered you question.
@@Jenuin Still don't understand what you are saying here bro! Please elaborate more? Thanks brother. Out
Very helpful. Feel like I've had the theory of this explained to me a lot but never really been showen when it looks like in the real world.
Glad to hear it!
this is really smart way of explaining ,I my self so excited this channel , and I'm one of the subscribers , and I am suggesting to add more industrial equipments like transformers ,air, vacuum, and insulating gas breakers , switchgears and more like that thanks a lot and keep going.
I blew up 2 of my inverters because I connected them to two 12 volt batteries in series. Thanks so much.
Great and simple tutorial. Well explained and very helpful, thanks a ton!!

If I understand correctly. My heater in my RV is 12v 3.4amp
Which means it can only run a maximum of 2.x hours total.
I purchased another battery...I thought to connect in series but thanks to your video I believe I must connect parallel.
Please correct me if I am wrong?
I've been freezing my buns the last month...lol
You would want to run in parallel
If you had connected it in series you would have 24v and ruined all your 12v equipment...
thank you.
You're welcome
thanks!
Very nice
Sir thanks for your sharing of this video in these time I have an idea...thank you and god bless...
Great video.
Excellent explanation! Thank you!!!
Well, i'm about to brûise my ego by showcasing my ignorance, but hey, Safety First, right? So, my questions are :
A) Wiring an additional 6V battery into an existing system of 4 12V batteries in SERIES/ (New one also in seris). So, since i'm touching neg. to pos., is there any danger of creating à spark?....and,
2) Will thé different voltage be any problem? Thanks/ love your Channel - very well-spoken & to-the-point.

Josh - don't know if you are still at RSP - I have a question for you. My wife and I picked up two decommissioned (never cycled) Absolyte GX 24 volt, 2,000 Amp hour batteries that we intend on utilizing for off grid power. I would like to configure them into a 48 volt bank. I am reading manual for charging each bank and it is saying to charge them at 54+ volts. There are (6) 2 volt cells per string/rack on each 24 volt bank - how does the manufacturer charge at 54 volts+ on a 24 volt bank? I have a lot of learning to do before I install these. I also may need a very large solar array to accomplish the charging for these 2 banks (if it is even possible). Is there a AC to DC charger large enough to run off a generator to charge these style of batteries? We have looked into EG4 48 volt Chargeverter - but that unit only works for lithium style batteries (supposedly).
Hi there! Thanks for reaching out with your question. It sounds like you've got an interesting project on your hands with those Absolyte GX batteries. Typically, lead-acid batteries like the ones you have do require a higher voltage for charging than their nominal voltage. This higher voltage ensures that the battery reaches a full charge without overcharging individual cells. As for charging them with a generator, you'll want to look for a charger capable of delivering the required voltage and current for your battery bank. While the EG4 48-volt Chargeverter may not be suitable for lead-acid batteries, there are other AC to DC chargers designed for this purpose. It's essential to ensure that whatever charger you choose is compatible with the specific requirements of your batteries to ensure safe and efficient charging. Good luck with your project, and feel free to reach out if you have any further questions!
Thanks!!
So does it matter where it pulls from on the parallel batteries? If I had the positive and negative wires coming off of one battery to my system, but connect the other batteries in parallel to that same battery, would it increase that way? Or should I move one of the main negative to a different batteries negative (while still keeping all batteries in parallel)
Hi, can yo uplease advise before I purchase the batteries. if I buy 6x12v 75ah batteries can I achive 24v 300ah or do I need 8 batteries?
Hey, can you link in parallel two 12v batteries, but different aH, say 110ah and 180ah?
No problem
So if I wanted to add a second bank of battery's to a existing set to increase amperage not voltage I would wire my second bank to the first bank positive to positive and negative to negative. Maintains the same voltage while increasing the amperage, right ?.
yes
Is a typical flashlight with two batteries an example of wiring in series? ....since the positive of one battery is touching the negative of the other..
awesome thank you 🙂👍🏼
You’re welcome 😊
Thank you for the information.
I do have a question, how to double maximum wH? I have a battery of maximum 2560wH but need around 4000wH
Thank you for this info! No I am not trying to make my son's electric jeep 24v powered 😆
Awesome thx
Where can you find the wiring harness to wire 2 wires to the same f2 terminal as you showed here in the “parallel configuration”
What about ..the other battery has higher amps/Hour ..can u connect them in series
is there any way to do this parallel without having a special double cord?? my batteries only have normal singular cords
Could the 10 amp hour battery supply .5 amp for 20 hours? That wouldn't be between the two values you said
What If I have 12v1amp load with a 12v 4amps source, can I use it for 4 hours continuesly?
nope 12/4=3hours
What about adding a charger to either of these ways?
Great
ca we connect two 12v batteries with different amp hour rating in series. for example 65 AH to 100AH?
I am trying to find these Y splitter cables for F2 connectors, but I am having a hard time. Any recommendations?
Hello. Great video. What’s the maximum number of batteries you can safely connect in parallel? I have 5 x 12v/100Ah LFP batteries connected in parallel with 4/0 welding cable and tinned cooper lugs and wonder if it’s safe to add three more. Thank you kindly.
nice thanks idol
Example 2batt.100ah .1batt.200ah ..can u connect them in series to reached 24 volts...
if you have 2 batteries, 12v each, in series, equaling 24v, aren't you increasing the power as well (P = VI)?
If i have a 12v to 220v 1400w inverter connected to 12v 200ah battery but i want to add 200ah another battery is it better to get 24v inverter or connect them in parallel and stay with my 12v ups ?
If I have 2 batteries both 12 Volt... one 100 amp hr but the other is 200 amp hr can we still connect them in series or parallel... if not do they have to be the same amp hours...?
Should it spark on the last hookup
With the same load applied, would these two configurations have a different runtime capability? I.e. to power the same load, would parallel (higher capacity) be able to power the load for longer? Or would the two configs provide the same runtime as a 24v load would draw half the amps as on 12v?
This is the answer I'm also looking for
If I need a 72v 60 amps battery for my electric scooter but only have a 72v 43amps battery will it still work?
What are the wires and connectors I need specifically for 12v12ah battery terminals in this video, thanks!
you can use any connector you want
He doesn't seem to answer.
I would look at gauge wire you have for your solar to battery and use that gauge or higher.
If more than one solar set up...increase the gauge a bit
Thank yoy
How do we calculate the wire size for interconnects?
I have a large Ah 24v battery bank I'm putting together but don't know what size wire to use. Been searching....
Oh, I have four 24V 230Ah batteries.
Please I need an advice! My questions is....Can it be possible to wire SIX batteries of 12V 220ah in SERIES AND PARRALLEL to give 48V 880ah for a system Inverter of 3.5kva 48V?
No, you need 16 batteries.
I have seen 195 AH @ 25amps. So, does that mean I can run a 25amp draw for 195 minutes?
If I connect the 2batt.series 100 ah 24 volts but still cap. Doesn't increased NOW if I connect the other 1pc 12 volts 200ah ..in parallel .What will happen ..Is the CAPACITY will increase?.
Hi is it possible to wire different Ah capacity of battery but same in voltage? Lets say i have a 48v 200Ah and i want to parrallel a 48v 100Ah. Is this possible? Thank you
so whats beter for solar, series or paralel? does it matter?
sir what is the battery and power required for electric motor having 24V,350W with current ratings of 16.5A. thanks
You just answered your own question, the answer is 24v and 350w at 16,5Ampere max power consumption ... So you need a battery that can delilver 16,5A at 24v at least... And how big capacity battery depends on how long you want to run that motor at full power. A 24v 50Ah lithium battery will be able to run that motor at max for 3 hours.
I have 4 12v 7 ah batterys that I'm trying to get 48v out of and can't figure out
Will it be better to hook the batteries inseries or parallel cause I'm using them for a 500w ebike. Can I use two of the exact same Scooter/Motorcycle batteries with a 750w Power Inverter to power my 500w ebike ?
If you connect the batteries in series you get double the voltage and will ruin your bike...
So will the two batteries I have give me more amp hours if I connect them in parrellel or just use 1 battery at a time ? What will be better so I can get more distance for my ebike ?
If you're looking for Amp hour increase, I believe you should use the circuit method. You're essentially just doubling the battery.
Connect them in parallel or else you double the voltage... When connecting 2 in parallel you double the ampere hours. If you use 1 battery at a time and change them or connect them in parallel do not matter, you get the same distance out of them.
What is a “bus”?
Hi people
I have 10 Batteries 6V 12Ah, bike batteries. How many of them can I charge in paralel connection charging? Does anybody know? I use them all in once and would like to find a way for speedy all together charging because I need to use and charge them every day.
What wire size are those?
Please explain why the A/H does not increase? does anyone Know why
Here's a good tutorial on basic electricity, explaining power. In short, voltage is the power, and the amperage is what is pushing the power. The amperage/amH is how long that voltage can be pushed. czcams.com/video/zYS9kdS56l8/video.html
What capacity? Say ampere or current, capacity is not written in the labels
Any of you electronic geniuses out there know how big of a battery I would need to power 2 technics turntables, a Rane ttm56 mixer, a laptop, a sine wave inverter and an amp/speaker (maybe a 100watt total)?
Would a 12v 50ah be enough to go 4-5 hours?
Also is there a way to hook up a solar battery charger to the amp and the inverter at the same time? So the it's charging the battery while the inverter feeds off of it?
One Duracell battery and an annoying stevie wonder rabbit with a drum will do the trick.
I have 4 12v 7ah batterys and I'm trying to get 48v out of the 4 batterys
12v times 50ah = 600watt hours or 100w for 6 hours... (actually more since the battery is more then 12v). But if it is lead acid type battery or similar like AGM you need double the watt hours or a 100ah battery because you ruin the battery if you use more then 50% of the total capacity. Lithium or Life-po batteries can be used to 100% with 2000 to 3000 charge cycles while lead acid only can take about 600 charge cycles to 50%.
Does running the two 12V batteries in parallel just double the Amp Hour capacity to 15, or is that calculated some other way?
new friend #PINAYUSA #HUNTERUSA
Makes no sense because a 24v system uses less amps when you're running lets say a 1200 watt appliance. You can double your running time because you're using less amps (using the same (2) 100ah 12v batteries...all because 24v allows more volts but it's the ah that matter.
Response: Thank you for your comment and for sharing your perspective. You've raised an important point about the relationship between voltage and current (amps) in electrical systems, especially in the context of battery setups.
Indeed, increasing the voltage while keeping the capacity (amp-hour rating) constant can have advantages, as you mentioned, particularly in terms of reducing the current draw for a given power output. This can result in lower resistive losses and potentially longer running times for appliances or devices connected to the system.
However, it's crucial to consider various factors when designing a battery system, including the specific requirements of the load, the available battery options, and the overall efficiency of the system. While increasing the voltage can offer benefits in certain scenarios, it may not always be feasible or advantageous depending on the application and available resources.
Additionally, balancing the trade-offs between voltage, current, capacity, and other factors is essential to optimize the performance and longevity of the battery system.
We appreciate your insights and encourage further discussion on this topic. If you have any more questions or comments, feel free to share them!
i need more ah so i take parallel
