You should not charge on a single cell. use positive on cell number 1 and negative on cell number 4, your batterys will charge better and prolong life. You will also get a more stable output.
You are correct! I've learned this as well, thank you for your comment!
YOU ARE CORRECT. I HAVE 4 HARBER FREIGHT AGM 12 VOLT 35 AM BATTERIES HOOKED UP IN PARALLEL AND CHARGE THEM YOUR WAY. THEY HAVE LASTED 5 YEARS AND ARE STILL GOING STRONG.
I was just watching to research that same thing
Cheers!, good info!!!
Would this apply to a x3 battery solar controller charger setup ?!? Positive on one battery and negative on 3rd battery ?
Your batteries connections are ok, between battery 1,2, 3 and 4. The thing is any load or charging device should be connected by the negative of battery 1 and the positive of battery 4 (or vice versa while connected to each other’s like in your video). This way all batteries will be in balance (amp wise...) in charging and/or load usage, otherwise you’ll be putting too much strain on battery 1 (or to whatever battery you’re connecting the positive and negative on) due to their each and own resistance.
Thank you for your insight.
Can you charge them all like that too?
@@ethanhooper403 Yes, it is actually the best way to do so or to have a load on them. I took the liberty to attach a web site link to better help you visualize what I’m talking about:
www.leadingedgepower.com/support/help-with-batteries/battery-bank-wiring.html
Hope it helps, good luck👍
@Fulvio .Abbate, so awesome of you to share and be helpful. You're a good man!
@@fixintodoitall I’m glad to help :)
Thank you for the video. What caught my attention with your video was the batteries you use. I am using the same name. Your question about the science and why they hold their charge at 95 percent is a good one. I bought my latest battery a week ago and have noticed after turning the inverter off my 4 batteries refresh themselves quickly amazing I would like to know the science too. Thank you, Alicia from Texas.
Don't connect your leads to first battery with parallel battery bank. Connect positive lead to first battery then connect negative lead to forth battery or vise versa. Then connect to charge controller. Your draw will be 13.35 amps to 11.6 amps to 11.6 amps to 13.35 amps that's 15%. The way you have it by connecting your charge controller at one end of your battery bank your draw will be 17.95 amps to 13.10 amps to 10.20 amps to 8.9 amps. There's also another way you can draw 12.5 amps straight across four batteries, but your battery bank needs to be wired differently in parallel. Hope this helps!!
@@TheShackLadylook up "balanced battery bank wiring". They show how to wire the 4 batteries in parallel to get 12.5 amps across.
Yes first battery, and last battery. Polarity
This is great, thank you for the video. I’m doing a dual battery set up on my truck and a quad battery set up for my Travel trailer
Clear and to the point, love it!
Can i parallel batteries with different AH.? And will it fully charge them all even with different capacity..thank you
Good info thank you! I’m your 1k sub. Congrats!!!
Ha, that is awesome! Thank you, I will remember.
Yes they do run them in 24v configuration it helps h
With some applications to run high load appliances
One helpful tip bit is the shorter your cables the better. Since your shooting for 12v your guage is probably ok.
Right cause that how I got my shed wired up from battery 1 to 4 from two 30 amp charge controller some say the battery don't work solar but I'm been with these batteries from last summer throw winter now here to another winter and I'm still reading what I started with so my renogy system never much get touched cause the Marine battery system so I agree 💯
Thank you for your feedback, and thank you for your support!
Outstanding!👍👍👍
get two flat thin copper bars that will go across the top of all the negatives and positive terminals. drill holes in the bars where the terminals are then strap all four positive and other for the four negative. You won't need all the wires and it makes a better connection. when you hook up the charger hook it up to the center batteries you will be able to charge all batteries full. Use the center terminals to draw from too. better use of batteries
Lol, that sounds risky. Should work, but I wouldn't recommend this to anyone. ;o)
Great VIDEO
Excellent insight.
Thank you!
can they be wired in 2S2P two in series and the two series banks in parallel?
A better way to confirm the entire load is to connect the positive at one end of the bank and the negative at the other on the charger/tester.
This is correct--Thank you!
Consider how the hot wire (+ or anode) literally touches the cathode ( or negative terminal) of the adjacent battery. For a TH-cam demonstration this is fine of course, but if these batteries are exposed to vibration or abrasion the insulation could eventually wear through presenting a catastrophic failure risk for all 4 batteries. You might consider adding in-line fuses.
Have you ever seen battery cables that have worn through the insulation from sitting on top of something? Not passing through a firewall or loosely secured where there would be movement and chafing. Just saying to get those cables which are prolly 6ga even vibrating your vehicle would have to be on a rough road. And if they were vibrating, they’re moving freely rather than rubbing against the terminals so even if those terminals were razors it wouldn’t be likely the insulation would be cut under the weight of the cable vibrating.
@@dirtyaznstyle4156 It's not clear to me the point you're trying to make. Is it simply "that won't happen"? As I stated "For a demonstration this is fine..." As for the "rough road" comment, my statement was "if these batteries are exposed to vibration or abrasion..." The pre-existing conditions are irrelevant: vibration happens in some situations. I said nothing of vehicles or roads. And your final point of "terminals were razors" I'll just say this: abrasion built the Grand Canyons. It should not be underestimated. See "oscillating tool" for a demonstration of what vibration and abrasion can do. For reference, I work as a repair technician for an ag. electronics company and regularly repair damaged harnesses. The manufacturing industry knows all too well about these risks, which is why most harnesses in vehicles are contained within convoluted tubing. I hope this helps you understand the risks, but all this discussion is really irrelevant: ANY situation which uses large [capacity] batteries and presents a risk of a short circuit, a breaker or fuse should be used, period. Good luck!
how much do you think that bench IN HIS HOUSE is vibrating?!
is this dangerous to do ? it give you lots of amp...
is this setup would old good in canadian winter? -20 c / -4f or -30 c / -22f
i was thinking of using motorcycle hand heater with solar pannel to keep them warm.. is this a good idea ?
To charge these equally, are you supposed to attach the positive cable to one of the batteries on one end of the row and the negative cable to the battery on the other end of the row? Thanks
Yes, correct. It's important all batteries have the same equal amount of charge before wiring them in series with each other.
@@fixintodoitall doesn't it apply to parallel connection also?
I knew this before watching this, but just watching this made me feel right lol. Im 26 and preparing for a world corrupted event. Everyone needs to know 100% what they do. I take notes i write and type them. Copies of all notes in hand. Solar and all. I am digging in to making my own power. I am in a populization of oilfield workers. Their corps are warning personally to their workers that it can shut down in the matter of a moment. Its been like that. Those people will be the ones who rebel on corrupt government control and will drill wells with what they are in knowledge of the old time ways of creating energy that will last for some time.
Good luck and god bless
Thank you for your comment!
I sure hope you are correct.
also I replaced my starter battery recently.vw t4 2.5tdi .got yuasa 100ah.was thinking could parallel my old starter battery up front.would it make new battery last longer?my stereo been upgraded.got hold of 2 Kenwood power amps and Kenwood 7x10 and made a subwoofer 10inch fosgate diy cabinet.when stereo on and using 2 amps the voltage drops 0.3 volts but usually have engine on with stereo.and both amps have control lead power so amps click off when stereo off.
@Steve, it might, but I'm not sure.
Steve, your old battery will decrease the life and capability of your new battery. Not a good idea to mix old with new.
hi.i have 2 x 110ah leisure batteries in my camper .have got dc to dc charger connected and have Waeco fridge on all time.works good.my batteries in adjoining cupboards.in camper van.when bought van another leisure battery is next to crank battery,it had split charger connected to it.ive kept it there as its handy to connect my spotlights that run off main beam switch .I used to have another 110ah leisure in back but would it be better to have 3 batteries close together in parallel.they not same age but same ah different makes .so I should charge separately sometimes you think?I have a ctek charger .steve
@Steve, I don't believe a difference in age of the batteries would matter.
@@fixintodoitall I'm charging each battery overnight with my ctek .they were 12.6v when started .may install another 110ah I had at back of van.but got power amp there now.fixin to do it all -youtuber says 4 batteries in parallel keep charge lot longer ..so hows your weather in Texas ,we had snow after rain all day .you happy with new presisdent?trumps had his day now
Will it hurt to run those batteries in series for a big house tv and ice box house size or do I need to get a mini ice box off six batteries, even though i got two 30 amp mppt charge controllers on the bank
The more batteries, the more amp hours you produce…No limit. Your Wattage output on your inverter will determine how much you can run off your batteries. Thank you for your question, and for your support!
Keep it going
I heard if you connect batteries in parallel, they equalize on their own after a day?
This is true, they equalise somewhere between the highest and the lowest individual voltages, into an average voltage.
The time this happens depends upon their individual capacities and voltage differences.
@@user-pz6cx8zf2y Correct. Equalize, yes. Be fully charged? No.
@@iNowHateAtSigns The purpose of equalizing a battery is to bring one or more weak cells in equal charging status. When this charging level is achieved the battery is considered as fully charged. If there is no other problem in the battery, equalization cures practically the sulfation of the cells by dissolving the sulphate crystals into the electrolyte, bringing it to its original density. When this happens the battery is fully charged. That’s all about it.
It is simple my friend. Unity is strength
Can you use a balancer with parallel batteries? Or will just connecting them auto balance in parallel?
I'm going to look into this...
This is tricky - TECHNICALLY they will auto-balance. However if there is a great difference between the charge levels then they would VIOLENTLY auto-balance. This could lead to off-gassing which could damage or destroy the batteries. This is exactly what the balancer prevents. The best solution is to fully charge them all and then wire them in parallel, as shown in the video, with fuses in between (30A perhaps, depending upon application.) If the fuse blows as the batteries are connected, something is not right and you need to re-check your setup.

I am planning on building myself a Solar Generator, using 4 12 Volt, Deep Cycle Marine Batteries, and a 6000 Watt Pure Sine Wave Inverter. My intention is to use the Solar Generator to fully power my 22 foot Class A Motorhome while Boondocking in areas with no shore power access is available, and gas powered Generators are not allowed due to noise ordinances.
Thank you for sharing!
so... if i run a 12 inverter on the four battery system you hooked up , i believe what your saying is i am still just using 12 volts but the system would last longer.. i am thinking in terms of off grid living . also if i hooked this up to my trucks system with a longer cable from my motor to my truck bed i could charge all 4 batteries at once from my vehicle or am i just not getting this lol
Correct my friend--You've got this!
@@fixintodoitall great thank you
Lmao me too bro plans to do this with the 4 batteries paired with a scrap alternator for powering it all just incase shtf
Hi , one last question can I use a different make of battery as long as they are same amps say 2 or 3 60 amps?
Yes!
@@fixintodoitall cheers mate 👍
Ahh! No! The current rating ("amps") of the battery is irrelevant. If the batteries have the same VOLTAGE rating they can be tied in parallel, as long as they're the same chemistry. Meaning 12V SLAs can be tied together, but don't tie together an SLA with a Li-Ion pack. Of course this all assumes you understand the best battery is going to be doing most of the work. I would not recommend tying different makes of battery in parallel.
What exact batteries are you using? About to buy some for my Van. I have a isolator kit waiting on them.
Sorry I'm just now seeing your comment. I bought these from Walmart. They are EverStart MAXX batteries. 29DC, 845 Crank, 114 Amp Hours
@@fixintodoitall no worries. Thanks. Still happy with them?
You have to check your months of battery Same length of cable and charge from inside out
What does that mean to charge inside out?
i have 3 of them. is it the same? and how can i conect outlet cable on the last one
Same concept, minus one.
If you don’t have all 4 batteries of the same amp hours, as I understand it, you will only be able to pull as many amp hours as the smallest battery. So 3 100 ah batteries and one 80ah would only pull 80 ah x 4 for 320 ah. This means 160 ah from a lead acid battery without possible irreparable harm to the batteries.
That sound 100% correct to me. Thank you for your comment!
Great video and demonstration but little advice with connecting batteries, always connect positive first than negative, reverse order for removal , negative first than positive 😀
Thank you for your comment!
@@fixintodoitall So who is correct?
@@forgetyourlife I've always connected the negatives first and will continue to connect the negatives first. I've never had any problems with connecting the negatives first. This is how I was taught, but I don't have a scientific answer as to why.
@@fixintodoitall thanks, I thought it was strange to read an opposite opinion without explanation. I’ll read up on it. Seems 12v stuff has a lot of different “right” ways to do it. AC you just get fried. 😆
@@fixintodoitall what about connecting 8 battery, 12volt each with 10kva 48volt inverter?
when you hook them this way are the Amps stay the same or they double?
They remain the same. You're only extending charge life. Thank you for your question!
Wiring multiple batteries in parallel increases available charge, measured in Amp-Hours. This setup can be used to increase current capacity (measured in Amps) but it must be understood that the batteries are not perfectly identical inside and the best battery (lowest internal resistance) is going to be doing the brunt of the work. Strictly speaking, this will increase available current.
@@iNowHateAtSigns If you have 4 batteries in a vehicle parallel do all negative batteries have to be connected together or can the batteries be grounded Separately and still work the same??
@@MrPolomitch The negative terminals must be tied together. If the batteries are in different locations on the vehicle, they can all be tied together using the metal chassis of the vehicle.
@@iNowHateAtSigns Thanks for the quick reply 👍..
Are all 4 batteries the same cranking amps or will this cause a problem
Mine are.
Cold cranking amps (CCA) is in part a factor based upon Internal Series Resistance (ISR). The battery with the higher CCA rating will do the most heavy lifting, and wear out more quickly than the lower CCA batteries. This isn't necessarily dangerous, and can be done, just expect the best battery to last the shortest amount of time.
THEY BALANCE EACH OTHER.
can this work with a electric polaris 4x4 connected to 100 watt solar panals
Great question, I'll look into this...
After seeing the date codes, I see there are 8 months different between the oldest and second oldest. Good luck. =)
Thank you for your feedback.
Can i parallel with different AH batteries? And will it charge all of them even with different capacity?
Good question. When it comes to electrical and even batteries, it is important to use the same electrical, batteries with the same capacities, etc. Never, ever compromise electricity. When you compromise electricity, you're only looking for trouble one way or another. This is the safest way my friend!
Yes, within reason, as long as they all have the same voltage rating. For example, a 5V 20Ah cannot go with a 12V 20Ah. Similarly, a 12V 1.5Ah shouldn't be paired with a 12V 500Ah. However a 12V 500Ah and a 12V 400Ah will balance fine.
For more info research battery Internal Series Resistance (ISR). This all assumes you're talking about Lead-Acid batteries as in this video.
*thanks for sharing it was very helpful I have two lithium batteries I’m going to do today. Did the wires come together like that from Walmart*
Glad I could help. The wires were sold separately. Good luck to you.
So wanting to do this to my truck cause I got strobes and want to hook a inverter to them so I can put a plug in in my truck bed if not obvious I drive a service truck
Try it out, let me know how it works out! Good luck!
Okay here's the problem I'm having, I have virtually the same deep cycle batteries and I have four of them like yourself, I try to put a trickle charger on them to keep them all charged up while they're just sitting not in use, this is a backup system if the power goes out for the freezer, however when I put my trickle charger on there the only way I get an indicator light saying that it is actually connected correctly and charging his when I put the negative to the positive and the positive to the negative which doesn't seem to make sense to me
One or more batteries might be bad.
I challenge you to prove me wrong, but I don't think you're actually keeping charge despite what the battery tester reports. The balancing of the batteries by tying them in parallel ensures they remain at the same voltage, and this effect takes a while to wear off when they're separated.
Try this: separate the batteries and let them all rest for at least one hour. Then test the batteries. I suspect you'll discover the weaker members of the group will no longer read the same as the stronger ones.
Thank you for your comment!
@@fixintodoitall It appears this is one of your top 3 most viewed videos. And while I can see TH-cam isn't your primary focus in life, I'd still like to see the test I suggested above performed if you're willing to take the time. As an EE your results don't track with my understanding of SLA batteries, and I'd love to do more research if you disprove my theory. Merry Christmas and Happy New Year.
I hv 2pcs of 100ah AGM Battery connected parallel, during charging with my mppt one of it get's warmer and the another ones, anyone knows why?
What does this means? Thank you if anyone who could help 🙂
I do have an e scooter trike which runs on 3 (6-DZM-12) each of them a single 12 Volt Battery Pack so 3 in a row making it 36 V. They are lead acid batteries. I took my 3 old ones out and set up the new ones exactly and wired them exactly as the old ones were in there. I put the 3 prong charger into the back of the scooter and then into the socket. The indicator light is flashing green red which I read indicates that it must be hooked up wrong with the polarity. I did not do anything different then it was before. It is exactly the same way although I think one connection is somehow missing from one to the other battery. I bought a multimeter and checked the batteries all of them are 12.7 V reading so all good. Then I checked the the charger with the multimeter. Also good. I am somehow thinking really something is wrong with the wiring. Is anybody maybe knowledgeable to help me when I am sending pictures ? I have never done this here before and I really enjoy my bikes but right now the are permanently parked 😞. I would appreciate every help I could get.
Wish I could help you with this. Anyone else?
How do I wire up four 12volt batteries to make a 48 volt battery I will be using this for a boat motor
I don't think you can. You can get 24 volts at the end from 12 volt batteries. This is my best answer :o)
series bruz
@Roblando33 all in series will give 48v He needs to do 2x batteries in paralell then connect them in series gives 24v with 4 batteries there are vids on how to do it its simple
Take the positive one the first battery and then the negative to the very last battery in the bank. So positive on battery one. And the neg on battery 4.
Thank you
4 batteries connected in series last longer for the same reason 4 horses pulling a heavy wagon live longer. Less drain and exertion on a single horse.

I'm trying to keep my 500w ebike charged as I'm riding. I have a 4lb scooter battery that powered on a 750w power inverter. So I thought about plugging the ebike charger in the inverter with just 1 small scooter battery. So I asked the man that works at the battery store he told me since the charger is 48v , he said I need to have 4 small scooter batteries to make it 48v. Do I need 4 batteries or can I just use 1 battery. He said if I use less than 48v it can mess up something. Is that true or false ??
I believe that to be true about having the four batteries. Attempting less could cause unwanted damage... Sounds like good advice to me.
@@fixintodoitall ok cool. Can I use different scooter batteries, even though they all are 12v. Like two of them are the same name brand and the other two might be different. Is that ok ? And I want to know the lightest weigh electric jump starters that has 700-1000w that has a 120v Ac power inverter. That might keep the e bike charged as I'm ridding ??
@@drrobotnikmeanbeanma I don't want to be mean, but you shouldn't be attempting this. Based upon the questions you're asking it seems likely you're going to hurt yourself or your ebike long before you achieve success. Consider doing MUCH more research before connecting anything. And remember: batteries can be dangerous.

@@drrobotnikmeanbeanma Okay, thanks for taking the time to reply. I'm an Electronics Engineer, but be safe and good luck.
You really should be using red cable for the positive terminals
Good suggestion, especially if others are using these batteries. The store didn't have red, and it's just me using this set-up. Thanks for your comment.
Since you dont have red cables, use some RED electrical tape on each end of the black positive cables. Just as a reminder that these are indeed positive cable.
What will those 4 battery's power and how long for? Cheers
Depends what size inverter you have. If you have a 2000 watt AC Inverter you can run a small air conditioner or a small space heater for a short amount of time. I plan to do a video soon with an inverter and solar panel. Life is crazy busy.

I haven’t combed thru the comments yet, but did yah ever find out why they don’t lose charge over a month??..
That is definitely an odd phenomenon
I have not received an answer. I would imagine over a much longer period of time they would lose their charge at a much slower pace. It just blew my mind there was no drop over 1-month. 12-months, I'm sure there would be a drop.
Can you eliminate temperature as a variable?
No

How to connect 3 x 12 volts deep cycle batteries with 1 x 24volts inverter, please guide with pictures.
I'm unable to do that at this time. Thank you for your comment.
If each battery was labeled A,B,C,D.
You should have them wired as
A to B, B to D, D to C on the negative side.
A to B, A to C, C to D on the positive side
Then your load/charge should be on
Positive = C
Negative = B
How do I connect four batteries 12 volt to get 48 volts at the end

In series
Nobody explained it here?

Single batterie will have a depressed voltage being alone 2 batteries are happier ther not alone 3 or more it's a battery party😀
Are they good
Mine still works. I've been somewhat satisfied with this charger.
How are your 4 batteries doing so far?
Good as new.
@@fixintodoitall Great to hear that. How often do you use them? Every day? Ones a week? What charger do you use to charge the 4 batteries in parallel? Have you ever charged them using a solar charge controller with solar panels? And finally how old are your batteries. I ask because I want to buy 4 also.
No problem, glad to help. All 4 batteries are 3-years old. We use them seasonally, about 6-months out of the year in our 5th-Wheel. I use this same charger during the off season to maintain their charge. I am happy with these batteries, but keep in mind these have got to be the least expensive batteries you can buy...they mught be junk in the next 1-3 years. If you have a higher budget, there has got to be better batteries you can buy. Just a thought.
@@fixintodoitall 3 years old is impressive. That means that the Maxx 29 DC with 2 year warranty aren't necessary. I was thinking of purchasing 4 Everstart H8 AGM batteries because of their 4 year warranty. But if your batteries last 3+ years I might as well buy the basic 29 DC. Do you add distilled water on your batteries?
I have not added water. Thanks for the idea!
what battery tester is that?
Schumacher. I bought it from Walmart.
You should always connect the positive battery cable first then the negative. If you connect the negative jumper cable first it makes a ground and that allows the positive cable while connecting to spark which could do damage to your electronics system. And for disconnecting your jumper cables from your battery you should always disconnect your negative first that will make it so the positive does not spark when you remove it. This is all my opinion research it before you do this.
How many battery's can be needed for 3000watts inverter for 1kv transmitter for a UPS connection
that is only for batteries in a vehicle, the frame is ground, so if your wrench touches ANYTHING in the engine compartment while its touching the + terminal, its a dead short to the frame & ground
I have same setup. Can you please tell me how to work out ccurrent draw on 4 batteries in parallel at eg: 50 amps in hrs to safe discharge? Deep cycle batteries down to 12 volts? Or is it 10.5? Any reply appreciated cheers from Australia 🙂👍
That is an awesome question. If you find out, please let me know.
12,04 is about 50%
I would never take a lead-acid below 11.8V. As other commentor stated, 12(.04) is a good cutoff point. So at 12V you have approximately 50% of Ah rating remaining. So, e.g., qty. 4 of 12V SLA batteries @ 50Ah each all in parallel, expect to run 50A for roughly 2 hours or 25A for 4 hours, etc.
@@iNowHateAtSigns I have 4 deep cycle batteries at 105AH each??? Any reply appreciated cheers.
@@dragan3290 Draining from a nominal ~13.8 V to ~11.8V, with all 4 batteries in parallel, you should expect about 210 Ah of actual available energy. If you want to go below 11.8V, I'd recommend you find a datasheet (or call the manufacturer of the battery) and inquire with the minimum safe voltage and DOD.
I wonder how long it would take to charge them lol
You always connect + 1st & - 2nd
I dont see any answers to your question.
The voltage across the terminals can not be used to determine the remaining amount of energy. To measure the energy you must discharge it.
Its better to keep lead acid batteries on a tender, so they are always topped off when you need them. even a 1W 12V solar panel will hold them up.
hooking 4 identical batteries together will not alter their discharge rate. I suspect your experience can be explained by the battery temperature when you measured the voltage or how cold they got while sitting for 3 months.
Interesting, thank you for sharing your insight.
It kind of sounds like with too bad you couldn't do it sounds like you might have a bad battery or going to have a bed better really soon and don't be surprised you could also buy a brand-new battery that is actually bad too.
Correct way is to connect to positive one end and negative other end
Wrong, that is series the voltage will be 48v = 12 x4 = equal a fried RV system, you really don’t understand parallel versus series....sad....
Ask Will Prowse😂
Thank you for your comment!
Unfortunately every one here is wrong. Wiring= positive,1 to 2, 2 to 4,4 to 3. Negative= 4 to 3, 3 to 1, 1 to 2. Charging positive to battery 1, charging negative to battery 3. This will give you a perfectly balanced charge. No disrespect intended I install large industrial solar systems for the military. Windy City as well as a few other have good one lines on series and parallel wiring. I hope this helps and good luck.
First off. You will have problems when charging battery's in parallel because the internal resistance of each battery is different. So if one has less resistance or the gravity of the battery acid is different strength then some will have more of a burden on the others. Yes the other battery's are loosing the voltage to the less efficient ones, so they may be draining while the others are charging, without the charger.
Now using the charger, if you have one battery that is at the highest voltage and another one is lesser, the charger will average the voltages and some will not get the top charge they need. Your better off charging them separately. Another thing if the tops of the battery's are not clean they provide electrical paths to discharge faster. Also the battery's will discharge faster if left on the ground. So they should be stored on clean insulating material to prevent that.
Make sure that all the connectors are super clean when connected. One way is to use a voltmeter across each jumper wire to see if there is a voltage drop indicating that there is a loose or dirty connection. even 1/8 of a volt can disrupt easy starting or charging without good and tight connections.
The most of this comment is correct for batteries connected in series. Not for paralleled connection.
Best comment so far .
Cliff jones whens yo nxt lesson cuz i just learned alot
Why do people make videos when they aren't sure what they are doing? Charge them all at the same time put positive on battery number one and the neg on battery number four,this will charge your whole bank even.same with your solar panel hook up to get the best charge.thank !you for trying to help but make sure you know what your doing before trying to teach others.
You can't get the last 15% out of any lead acid battery. So your claimed 488 amp battery is really a 414.8 amp hour battery. Then at a discharge rate that is considerably higher than the 20 hour rated discharge rate, after a 50% discharge, you really should pretend it needs to be recharged because the discharge rate begins to drop faster. So a 400 amp hour battery should be considered a 200 amp hour battery if it's a lead acid battery. Lithium is a whole another world.
your statement is not correct
at 100 A-hr battery will deliver 100 amp hours at the current in the spec for that battery.
if you drain the battery faster its output is derated
if the battery is cold its output is derated
you can find the battery discharge curves on the company website
I can tell you the difference where I won doesn't work very well why two don't work very well with three don't work very well what food don't work very well why 17 don't work very well wire it up like you do cuz I wire mine up that way the problem is if you take it and drain it down to almost nothing everyday which you're not supposed to do the last least and typically they should last you at least 10 years regardless but that's just a lie. The problem is if you lower your battery is down to almost nothing all the time the battery loses charge it's better if you don't hard to use the batteries all together would use in all the power but just some of the power and the battery's last about 20 30 40 years I know I have some batteries that old that still works like a charm they're called lead acid batteries.

You sound like trump to me. U should do impressions! :)
Hmmm... I wish my bank account looked like Trump's. Hahaha
Connecting the Neg to pos ? Wouldn't that cause an explosion!
Yes, if you do that on a single battery, but not if building a series string of batteries (in order to increase the nominal voltage).
Hahaha, yeah and fun to watch. But I never recommended it. Lol
I've given you a simple chart so you will understand how your maintaining your amp hours and voltage. I hope this helps you understand. If not just enjoy your batteries.
×%÷12=80h×495^12.7%vt=420÷4=400+1.2×24 =28.80vt@95%
Why does 41 battery checked the other batteries as if any other battery was lower all the bears equal out into the same power level by shoving all its power to that battery until the equals out to the exact same the gold put a half dead battery on the end of watch it just jump down into almost nothing until equals out but won't jump down to nothing but you sit decrease quick quickly that's what I run has ever start lead acid batteries 1000 amps 135 amp hours. I have to do two different systems all that as a batteries because that's what I get for that $93 a battery two different systems always 212 make a do test because everybody wants to complain and say something different so I was tried over and over and over again and get the same thing proving them wrong yeah I got a big asset that I used to run my house or part of my house anywaysb, because I don't have enough solar panel to run my house.
Can’t any of you guys that do these videos JUST PLEASE Show quickly how to wire the batteries without talking about STUPID MISTAKES OTHERS DO. A Simple showing of the wires would suffice for many of us. The Stupid Mistakes RV ers make is another video day for you.
Tt
Thank you
Guy you shouldn’t be explaining things if you need people to help you in the comments . Also any newbie can’t see where the wires go at the top of the screen. You physically can’t see the whole picture.
You hold more with 4 because resistance is same as the field making full in the bank if u halfed that it is half the bank taking 2 times the heat still and that on a lead acid is acc on both batts being due to "the piggy backs".
If u know a circle (physics u are eqaul to "4=to pie (3.) 3 is a 1/3rd of 4 a circle, pie is =to sin (.5of that/ cosine .5 of that oppositly posative negative, sin and cosine is =to soh-cah-toa in its pythegreum/ Kerchofs law/e=mc^2 >fourier function displacements time energy pushh pull rotation/laplace/and degree in its space to heat and time to its conserved power at witch is 12v cells with alt (maximum) field of primary windings and secondary, diodes/magnets(emf)/ frequency fundementals/AS well too pwm (comunications or other communications /protocals)
Parrallel "4" 4÷2is =2vcells
2÷2 from wires being parralel is "1"
Thank you for sharing!
@@fixintodoitall nooo, :p thank you for sharing
.001 maybe wrong but im talking 100 and that is 3 times the vallue to place ment tho divide in paralel terms and parralel is half that of what cosine is which is =to its maximum in independence takeing what it needs supplying the next ( just like a electrical tower supplying many houses and not droping untill rlly demand alott or weather is "negative degree making below atmospheric pressure" the atmospher is the minerals of anything matter.. really tis atoms and molocules
Trapped in a "space" its space like us in the midle of gravity being pulled from north and pushed down south(up), from south pushing/pulling north cause north is oposite so (west and east are 90° apart shifted in perfect radius to times aspect of space and pressure.. well pressure is a density of somsort with a mas of some form or mechanical or elecricaly imnduced force making "X times the power (^2to9=3:2:1 at witch elswer time could be 1423 exurted pressures elsewer to a number in time to a power 1423 we do know is a firing order or pattern of a 4 cyclender is 120pounds.. injectors. Tho thats a maximum half that is eqaul to the pressure it is trying to pull/pushh being equall everywer else to its resistance of force in time to its space in wire as resistance and independence is independant to its space compared to its maximum resistance in asked for demands to voltage and current compared to its capacitance of within resistance of itself (battery) but anything even house power from 480 made 240 120 plus 10 is 250 6phase same can be said in alternators and components of circuit boards (kerchofs law/ohms law)
Wrong
Thank you for your comment. What’s wrong?
