Battery Bank Options + Wiring Solar Batteries from 6v to 12v vs 24v

[@DuetJustusFam]

Hope you guys enjoyed the video 😊 Be sure to share this info with anyone you know who is interested in solar power. It really helps us out. Thanks for watching and I'll see you in the comments!

[@battery_solar_ev]

not aiming to step on your toes but 9:03 12 volt set up your outputs need to be off set for a balanced drain and charge so that one battery is not taking all the drain or charge first. Path of least resistance always stands with batteries. The way it is set up in the video one battery is always playing catch up and the one that is the first out is the first to fail. Good effort on the breakdown and explanation. Have a good day

[@youtubecommentpolice2043]

Duet Justus what about these 12v batteries that have 75a. .....they are like $30. Would these work for a small system

[@davidstephens1092]

Something for you to consider for your next comparison is lead carbon batteries. The negative plates are treated with carbon to reduce degradation . They have similar performance to LiFePo4 , 3000 - 5000 cycles at 70% DOD , they are designed for Partial state of charge operation (PSOC) are a lot less expensive and are safe. Yes they are heavier. The other point I would like to raise is ,With the way technology is advancing, Is it worth going for something that will last 20 years, when it could be out of date in 10 years.

[@mikeshargent8948]

Not certain about the points made but ,if anyone else wants to uncover homemade solar energy try Magonsi Solar System Expert (just google it ) ? Ive heard some great things about it and my co-worker got amazing results with it.

[@buffalo_chips9538]

In 2-3 years the solid state batteries will make all of these obsolete.

[@mikemecklenborg5412]

The best video for connecting batteries together I have ever seen. I clearly understood how to connect my three 12 volt lead acid batteries to maintain a 12 volt system to run my 12 volt to ac converter and to connect my 12 volt 100 watt solar panels to charge these batteries. I got the batteries for free from my son-in-laws business and had the wires built 9" long to connect them all together in parallel from a website on amazon and everything works great. I have 300 ah at 3600 wh and divide that in half or 50% of usage of the batteries gives my 1600 wh of usable energy. I was just given another 12 volt battery to connect to it so I am glad I order 4 set of negative and positive cables. I'll then have 400ah at 4800wh divide by half and I have a 2200 wh of usable energy. Its running great.

[@mikebushert594]

Thank you. Confirmed my purchase. Also learned I have less usable energy than I thought, but the longevity of my first purchase of 6 Volt lead acid did last a satisfactory 8 years.

[@solardiymadesimple.3779]

I’ve been running most of our home off grid for around 4+ year now and my lead acid batteries are doing just great. Yes I agree you have to maintain them regularly but if done correctly they will last years. Just waiting for these batteries to give up before considering changing over to lithium batteries,that being said it all depends on the price.👍

[@DuetJustusFam]

Thanks Vincent, You are very welcome! 🙂

[@xanataph]

A couple of things to consider with lithium ion batteries. If you *do* end up over charging or discharging them they'll probably be toast. And if they catch on fire, have fun putting the fire out! Lead acid batteries might be old tech, but they are far more robust. They can handle more abuse and are probably the better choice for someone beginning with solar power.

[@DuetJustusFam]

I really do like my lead acids. It’s definitely a trade off and if I were to install again, I would definitely need to weigh all the options. Thanks for taking the time to share this info 👍🏼

[@xanataph]

Cheers for replying. There's a couple of other interesting battery technologies out there too. Nickel-Iron (Edison) batteries & Salt Water Cells. And of course some people run industrial size NiCd cells too.

[@giottodiotto1]

the FIRE problem is practically non existent with LiFePo4 batteries, people must make a study on the differences in Lithium batteries, the mostly in small batteries used chemical is LiOn (18650) and YES they are a bit dangerous, the LARGE prismatic cells in LiFePo4 chemistry are in fact very hard to ignite, so check out the BIG difference between these.....

[@xanataph]

Agree, LiFePo4 batteries are far more stable and safer. But at the expense of reduced capacity. But practically all those involved in making DIY power walls and the like are predominately using Li-ion chemistry cells recovered from old laptop batteries etc. It's triple jeopardy really; using unstable cells, second hand with different lifespans left in them, some people not really knowing what they are doing. Did you see that video on the VW combi going up in smoke when a pack of Li-ion cells was left charging?

[@brianjackson38]

Lithium ion batteries are more safer, its very hard to ignite them due to the fact that the constituent cell is made up of small finger-like batteries that are also inside a metal exterior. On the other hand, lead acid batteries release hydrogen gas when charging and sulphate at the terminals over time.

[@Kecarter1]

Great diagrams much appreciated. Have been chewing on an upgrade for our trailer for longer dry camp times with litheom ion batteries. We where not sure on the solar for the moment since our preferred camp sites are heavily wooded and light limited. But the 80% useage helps camp stay and also we can run generators for some recharge as needed. This video is helpful as we work toward this goal. Thank you.

[@snek9353]

His depth of discharge info is wrong, the AH ratings take that into account already. For an RV, unless you are getting really into it lead acid is the easy choice as it pairs up well to be charged from the tow vehicle.

[@ryanslut5607]

Do you get much wind??

[@grovedas]

God bless you for explaining all of this so calmly and slowly and clearly. Because of you, I finally understand how to wire a battery bank. Thanks again.

[@whitelfner4582]

You do understand that forklift/traction batteries are designed to go down to 20-30% state of charge DAILY and are warrantied to do so for 5-7 years, You CAN go below 50%, and with a home system you can plan to do so rarely and be fine. My Forklift battery is 24V 660 ah and would cost $2700 to replace, It is 12 years old and will need to be replaced in the next year. Comparable LiFePo4 would cost $4500 (today 2022) and it would also have to be kept warm, my lead acid battery banks have always lived outside. So some additional cost there, something you neglect to mention.

[@DuetJustusFam]

This is great information. Thank you for taking the time to share it. 👍🏼😎☀️

[@DankDadReviews]

You should be an instructor. The way you explain things always hits home. I’m having so many ah ha moments watching your videos. Just awesome!

[@khalidiqbal5567]

Agreed

[@rossallen738]

I found this super helpful. I am converting a school bus into an off grid tiny home. For me, the Lead Acid batteries just make more sense. Yes, you have to maintain them, yes they don't last as long as what they claim lithium ion batteries last, but I don't plan on keeping the school bus for 20+ years so I wouldn't get the full value of the lithium. I honestly only plan on living in the school bus for 5 or 6 years. Also, The cost in this video is slightly outdated or not well researched for lead acid battery cost. You can find 215 Ah lead acid batteries (6v) from Sams Club for $90/each. Duracell brand which from my research, these particular batteries are rebranded Deka batteries. So I can get 8 Lead Acid batteries for the price of a single Lithium ion battery. Sure, I can only use 50% of the capacity, but its MILES cheaper. With proper maintenance, those batteries should last me the entire time I live in the school bus.

[@KD0CAC]

One of the better videos on this subject , but you could have bumped it up a little with the + , - of charging of each and the issue's of charging in parallel / series . Thanks

[@Rhythmfiddle]

Great presentation of a challenging topic! However as they say, the devil is in the details. As a part time RV'r my needs and long term prospects are different than a full timer. For example, your cost per AH implies premium batteries which can handle some extra abuse. As a part timer, I'm very satisfied with 2nd Tier AGMs such as the Universal that can be had for as little as $1.75 per AH. Also AGM batteries (and Li-Ion) do not need venting, and for cold weather are best placed inside the camper. A security issue for many small rigs with outdoor battery storage. My batteries only cycle about 100 times a year, and I plan on keeping the camper only about 6 years. So Li-Ion will never really pay for itself as I'll beat my rig to death on bumpy Interstates before it gets retired. Also in 10 Years some new battery tech will come down the pike and my $5 per AH Li-Ion battery investment will become "Old news". Lastly is the issue of the inefficiency of the 24 - 12 conversion losses needed to power all the 12 V appliances, lighting, and chargers an RV would have. That can offset some of the efficiency gains of of the lower line loss of 24V systems. Thanks again for a great presentation and channel!

[@markwattsoregon]

Besides the four categories considered here I also would add weight as a significant advantage of the lithium ion option over the lead batteries.

[@jdwilsun]

I really appreciate your beautifully clear explanation putting everything in perspective. I am feeling rather stupid as I must have missed the obvious point! In my mind, if Li @ $3,000 is 5X ledAcid @ $600, & Li last only 5X longer, the cost is equal. (maintenance & replacement work aside). I imagine in 5 years there may be a superior battery to any now?

[@dakdjonsey2398]

Depends on how long you'll actually use them. Old timers like me may not love 5-10 longer. Or, somebody may trade off their rig in 3 yrs for whatever reason. Be sure to figure in longevity in your thought processing... hahaha

[@joeo7257]

Great Video! Super basically: When you take the covers off of your car battery, you will find 6 holes filled with fluid. Each of those are individual cells producing around 2.2 volts. They are internally wired in series making around 13.2 volts. (but called 12 Volts). If you use 6V golf cart batteries, they won't do you much good unless you want to start a tractor or own an super old Volkswagen bug. They only have 3 cells per battery, so you will have to add 3 more cells. (another 6V battery). By running a cable from positive of one battery to the negative of the other, you wired them in series and you will have a large12V battery. When you read your battery it will tell you how many amp/hours it has in it. You were able to double your voltage, but you can not double the Amp/hrs, they will remain the same. A parellel circuit requires 2 cables (obviously) Positive from one battery to Positive on the other battery, and on the other cable Negative to Negative. If you wire two 12 Volt batteries this way you do not double the voltage,(which is good) but you get twice as many usable amp/ hours. This is very common on RVs. Keep in mind, two six volt batteries wired in parallel will have allot of amp/ hours, but still only 6 volts, which will not work on your RV or car.

I have two questions. First, I don't remember what channel I got this from, but they were saying you can take a 24 volt solar panel array, feed it thru a MPPT controller to a 12 volt system. Can this safely be done. Secondly,, with lead acid batteries one cycle would be when the batteries reach a fifty percent charge? Thanks

Thank you *very much* for the comprehensive yet straightforward explanation of the advantages and disadvantages between the 3 main battery types, costs, and performance capabilities! You conveyed the information virtually as straight and simple as I’ve seen- and I’ve watched MANY videos on this topic only left feeling more lost, dazed and confused most of the time. But I obtained a much finer and more accurate understanding of the energy storage solution I will likely use (3rd one) and precisely how to configure/combine them safely and properly- especially for higher Amp-hours, minimal maintenance and years of sustained performance and Energy output over the years which I absolutely need. I am currently actively planning out my home solar power system now, scoping out the best components I can find (a real toss up sometimes) and literally can’t wait to become more energy independent all-around!! The only other thing I would have really appreciated was if you also included salt-water batteries in your comparisons and explanation... Bravo and well done! Thanks again for taking the time.

[@TheBigfoot567]

Nice, understandable video. I can readily find 2-3 year old used UPS 12 volt AGM batteries at 100-125 AH on craigslist for $65 -75 each. I have some AGM batteries that are still working that I bought used. Manufactured 14 years ago, with occasional use in a remote TX cabin. I'd like to change to Lithium... but too pricey.

[@marthsdiang8884]

Perfect. What a clean and excellent explanation.

[@geoffowens4622]

I work for a major oil company and do project NPV calculations all the time and we would never use a 20 year life cycle analysis. The odds on you owning that camper 20 years from now is pretty slim. In addition, the odds on no new innovation in the next 20 years is even less than you owning the camper. I can get 5 years from my FLA battery before I recondition them and get anther 200 cycles. A good FLA is really the right choice for me and that’s why we have options and we need to do what makes sense for our own situation. If you took the difference in the cost and put it in the Russel 2000 our any other good indexed investment you could buy Battle Born. I think Battle Born is a great business and very committed to the recreational travel trailer industry, I’m just not buying their value proposition. With that being said a great video, and a very impressive battery installation. Geoff O

[@fabonline9389]

By your own numbers I can replace my lead acid batteries five times for the cost of lithium . I have had banks last twelve years with no problem so, the lead acid systems will last 60 yrs compared to lithium's 20 for the same cost. Until the numbers balance out, I'm sticking with lead acid.

[@b2451]

agreed. One more reason is that the Lithium battery price will very likely go down in coming 5-10 years or a new tech will emerge as even better choice. I will wait.

[@crpth1]

Can't agree more. If the particular need imply mobility, like in RV, camper van, etc. the case for the lithium's pile some more advantages. Due to smaller foot print and weight. But on fixed installations, the lead acid batteries, I believe, will rule for several years. After all weight is no issue and foot print probably is no concern either. But cost on the other hand dictates the out come quite clearly! ;-)

[@orlandoortiz689]

best explanation for battery bank i have yet, keep on, Thanks from puerto rico

[@soaring16]

I agree with all you've said with one slight caveat. Lead acid and agm can be purchased anywhere. For those in the prepper community, access to lithium batteries might be impossible should a shtf deal happen. Conversely, with all the dead on the side of the road vehicles around, access to 12 volt batteries won't be a problem at all. The other point to make is it's easy to add more capacity at a cheaper cost than Lithium. (8) 6 volt batteries in series/parallel would provide huge power and probably never get anywhere close to 50% discharge. Many RVers use the (4) 6 volt batteries simply because their power requirements don't exceed even 70% of charge.

[@longhairmullet]

Bob Bradley and the fact that adding 4 more 6 volt batteries will be adding another 300lbs if the batteries are 75lbs each. So (8) would be 600 lbs. weight is a big consideration when building a van conversion.

Great video, give one a great perspective on setup and cost, which for lot of us is a factor, if not a major one. I've not found anyone that has done a video "just" on a straight battery bank to service a house. So my goal is to have a large enough battery bank to put out 350 kwh per month, 11.66 per day,, and this is a bit on the high side. For now I will charge the batteries with my generator, eventually I'll add solar panels to help with this as well. So what I'm trying to learn is how many 200AH batteries would I need to give me the 11.66 kwh per day needed?. Thanks

Nov 25, 2017 Ignore the other post messed up format on it In this system was my setup with NI-Cd batteries: And to give ideas: Just for info look into flooded Nickle Cadmium (Ni-Cd) batteries: My first solar / multi power system (solar, wind, and water wheel generation set-up) the system that I started the set up in 1980: I went to a train repair yard and got the 2 volt flooded Ni-Cd batteries for free with the wire's: They weighed about 75 lb each: When I got them home I made 12 volt banks; then wired them into multi 12 volt banks (For a power generation system of 6000 to 10,000 amp/hour) with enough battery reserve to run my shop and trailer easily for 2 to 3 months without any solar, wind, and water wheel generation input: I built this system over about 10 year's (Up grading my 2 volt wet cell NI-Cd batteries and solar panels and generator's "For wind and water over the year's") from start of project is 1980 until my 5^th wheel was burnt down in 2001: The wet cell Ni-Cd batteries of that time could be discharged down to between 2% - 5% and was best to do so if not just maintaining them (So they would not form "My NI-CD" a higher % memory discharge - 'discharge to 50% if do so they will drop very fast past the 50% a point where the could not be used and need a full recharged' and "Maintaining them between 97% to 100% to keep the life span very long with a very deep discharge befor a memory drop off" occasional discharge down to 2% from time to time is good for them): Now with today's technology you would need far fewer batteries than I needed at the time I started my system (I have been buying equipment for a new off the grid homestead system with multi generation capacities and locations): But if you build this type of system research all type's of batteries / battery system and battery voltage's and Amp's from 2 volt to 24 volt and even higher voltage's and high Amp's in a single package ", ie: 96 volt" (Even look into starting with used car batteries and upgrade as monie allows): Now I can not stress enough for you to do "YOUR RESEARCH INTO ALL DIFFERENT SYSTEM'S" To find a system that will work and/or start out best for you with upgrade's as monie, capacities, need's, and ect. "again Homework, Homework,Homework, Homework, and even more Homework. General info for my new system: Like power for my water well solar with battery storage but when the batteries are full just maintain the batteries then the extra generated power sent to my main power house where all my power generated is stored; (Where all of the battery storage system would be located) "Like from my water well, night time security lights, shop power, green house power anything that uses a little power but still is generating more than is needed, and ect" They don't use every thing at once; each of the befor mention system's have their own power system's but are able to send power to the main power house and receive power from the main power house when needed: Again discharge the system from time to time that is recommended for your system.

[@JJ-kf2uk]

Could you discuss drawbacks/anomalies of parallel battery circuits? I'm old school and the wisdom of those days forbid batteries (dry cells, wet cells, etc.) from being connected in parallel. The premise was that the parallel bank only performed to the limitations of the lowest performing cell (discharge rate and voltage level). So it was never a simple matter of increasing current capacity by multiplying the number of cells. The net gain was mostly disappointing. I have always assumed that there be some sort of isolation/"ideal diode" circuit for those battery banks with parallel connections. Has this changed and now simply ignored?

[@giottodiotto1]

you forgot the fact that the Lithium batteries have a much lesser PEUKERT factor, when you put a big load on lets say a 200 AH rated (at c/20) lead acid baterie , the capacity drops like a rock, so in practice it wil behave like a 75 Ah batterie (100 ah sinds we only can use half of a lead batterie , minus the anoying peukert factor) so i think that in practice two 100 AH lithiums wil be simalar to the three you mansioned....also with a far lower voltage drop, and not to forget a 40 percent HIGHER charge efficiency, very handy during rainy days in the winter...otherwise a GREAT video explaining these batteries!

[@julianfigueroafrias9133]

Excellent. Explanation and comparison

[@3DPDK]

Concerning flooded lead / acid batteries: Don't get confused about the 50% discharge. The listed amp/hour rating of a battery, if the manufacturer is honest, is the amount of amps the battery will deliver consistently for *at least* 20 hours. This is the industry standard "bench mark" test. If a battery is rated at 200ah the 50% discharge limit does *not* mean you will only get 100 amps out of the battery. It means the battery is capable of putting out 200 amps for 20 hours - which is actually a huge amount of current only found in 8D group size batteries or bigger. Only when the battery reaches a voltage of 11 volts will this current capacity begin to (sharply) drop off.until it reaches 10.5 volts; considered to be "dead". Another thing not mentioned is to make certain your system is using "deep cycle" or "deep discharge" batteries. An automobile battery is physically designed to deliver a large amount of amps in a very short period of time and rated as Cold Cranking Amps. The thinner, more numerous lead plates inside the automotive "cranking" battery can deliver the high current, but will quickly build up with permanent lead-sulfide scale that eats through the plates or shorts them out if discharged too deeply, too often. A Deep Discharge battery has fewer but thicker plates. This results in lower discharge amperage but gives a constant current over a greater period of time. Because the plates are physically thicker they are not as easily damaged by sulfation and can, by design, be discharged to lower levels more often than an automotive battery.

Very helpful and easy to comprehend. Thanks

[@Whogaftbh]

Tysm for these 😭😭 I have no idea about the electrical of any of this

[@tomstdenis]

Don't know where you got your AGM info but the FullRiver AGMs I have are rated for 500 cycles at 100% DOD and 1000s of shallow cycles....

[@rampagededat5296]

do you have a video on sizing batteries to solar panels? for charging etc...

[@alexdmeza409]

Thank you again. This information was really clear and helpful.

[@CelebrateEverything]

Thank you! You made this very understandable.

[@CarriesWater]

Awesome information😃 I really appreciate the way you relay this information. I'm about to start my 1st job in the solar field. A bit nervous. So your channel is awesome dude, cause it helps...

[@DuetJustusFam]

Awesome! You will do great. So glad the videos help. Thanks for tuning in 🙏🏼

[@RemjiusMiyaiodongo]

Do you have a video on battery bank sizing?

[@b2451]

the video may have missed a key consideration factor, i.e. operation temperature. Lithium ion batteries have problem in charging below freezing. I think that is very important to consider.

@A L - Keep it warm or buy a self-warming battery ...

[@tapiwanaishemapanzure218]

Thank you very much for such an informative video

[@mkuselimqana]

Very very helpful. Thanks a lot Duet.

2 gripes with this video. 1. Cycles vary with depth of discharge. My AGMs give way better cycles than what yours listed. I went with agm because they tend to have higher AH/$ and had 7 year warranty. 2. I forgot. Other then that. Pretty good.

[@DuetJustusFam]

I’m not positive but I’m sure the AGM technology has progressed since this video. That seem late like you got a great deal! 😎☀️👊🏼

[@klouism1]

Excellent video. Thank you. I appreciate the information. Stay well & keep having fun.

[@BlueCollarDIY]

I love this video. I send it to a lot of people I see asking basic questions. But one question I haven't figure out yet is, what is the advantage or disadvantage of having a 6v battery vs a 12v battery? From what I can tell, they're both similar in price (when comparing ah).

[@ZulaBee]

The answer could be another separate video, but in simple terms, voltage X amps = power (watts). Higher voltage systems (48V vs 12 volt) require less current (amps) to provide the same amount of power. Less amps means cable /wire sizes can be smaller (less expensive). Notice that electric appliances with a heating element (dryers, range tops, etc) require more power (watts), so they are designed to run on 240 vac which requires half the current than if it was designed as a 120V appliance. Hope that made sense.

[@khalidiqbal5567]

Nice but what about warranties of all three...? Lithium ion battery comes with 1-month I heard, unlike 6-months for flooded and 2-years for Tubular battery. Appreciate your answer. Thanks

[@BWWGL9]

Duet, if you wire say 4 of the 6v flooded batteries, in Series and Parallel, is your Solar Power/system... going to "BALANCE" Charge your batteries ? Seldom do I hear anyone speak about BALANCING your Batteries. Please let me know. I enjoy your Videos, you speak clearly and a educated on what your providing to the Public. Thanks
