Will Prowse how long will this power a energy star 5000 btu a/c after sun goes down?
Will Prowse: Firstly, a great video yet again.
The link you posted is to your previous 12v build, will you be updating it for the 24v build? Edit: I see that the link now includes both the 12v and 24v builds, thank you.
The new look bus bars look very professional: Are they also made from flattened copper pipe and shrink wrap?
The cell terminal covers are slick as well: How are they held in place and can you share the plans to build them?
@@joshuablack4575 it will depend, these are used batteries and its a gamble on how much capacity they will hold. also how many watts your a/c will draw. will they be fully charged when the sun goes down? im guessing that your ac uses 600watts and the 8 used batteries should roughly have 280wh each capacity x 8=2240wh divide by 600watts = 3.73 hours. you may get more or less depending on your ac watt draw and battery watt hour capacity. also if your ac compressor kicks on and off only 50% of the time then you can double your hours.
410 watts @ 3.7 amps
Or how about a balance charger?
As a retired Senior Chief Electronics Technician, Submarine Service, who is an x-instructor of advanced electronics in several areas (radar, radio, cryptography, and servomechanisms) I can say you are one excellent teacher. Your style makes it interesting for folks of vastly different levels of skill. Thank you for making it fun again.
Your comment made my day 😊👍 thanks
He's like Sheldon Cooper's little brother
Yes he is
He’s grown so big the past two years and at first I thought he was pompous but I was very wrong, I wish I had a friend like him
This guy has his whole act together better than anyone I've seen on you tube on any subject matter. Take, for instance, just the time he puts into writing his descriptions for his videos. Every single detail is included for convenience to the viewer. Then, you consider the fact that the information he conveys is seldom challenged in comments from so called "professionals" and it's easy to see why his videos are THE go to resource for all things solar powered. This is what happens when someone is passionate about what they're doing, doing what they love, and energetic. I have no idea who this guy works for. But, I'm guessing he gets many offers from many companies to consult or work for them. I hope he does his own thing. The world is a better and more environmentally friendly place with this kind of talent permitted to share what's possible. He has no competition in this entire category. Really an impressive and professional presentation every time. Thanks. Subscribed.
Thank you so very much. Your comment made my week. I really love what I do and for you to see that, and appreciate it is great. I have a lot of projects lined up for the future and I can't wait to show you. Thank you so much for taking the time to write this out, Stoneyrun. :)
Great resource--I am learning a lot, now I just need to figure out how to add some solar cells to my current unit.
Hey we have the same profile picture!!
Thank you very much ....
please just stay honest and don't fall for brand sponsorships. keep up the good work.
As an electrical engineer I can say this young man really knows this subject. Well done!
He really nailed it ! He showed us everything and answered our next questions as he went and then gave us the links to allow us to do it ourselves.
Great educator,sales person and visionary !
Agreed, however the terminals are also the current collectors, in Li-ion batteries copper and aluminium is used. I guess the colours are "silver" and "brass".
Eh, kinda. "This terminal is +24v and this one is -24v". No that'd be a 48v supply. One is +24v the other is 0v, this is pretty basic electrical theory gotten wrong. He also doesn't cover a lot of safety precautions for handling Lithium cells, there is a crapload of current capacity there with decent voltage behind it and we don't know if these cells have internal protection or not. Accidentally shorting this array could have it go up in flames really quickly. Especially as brass terminals under that kind of current could essentially braze themselves to whatever shorted them, breaking the short can become difficult. The output terminals (especially being that close proximity to each other) should be covered at all times to avoid dropping a screwdriver or spanner across them.
please provide a link to buy those batteries thx
Flap Zapple hey sorry to bug you, but you’re an electrical engineer so hopefully you could give me a clear answer.
In 3 minute mark of the video he states its best if you keep them in 70° conditions. I’m very interested in potentially building this, but I plan on living more off grid and I’m currently living in Florida so I think my overall temp might be worrisome because it’s often over 70 at night in Florida when I’d probably stop running A/C
Would you recommend I try and save money for traditional battle born or do I just run into the same problem?
Really nice tight editing. He doesn't waste a second of the viewer's time.
Will, you've done a great job on this build. I've been watching your videos for quite some time both on solar and RV homes. You just keep growing and I will continue to recommend your materials.
Keep up the easy to understand approach it works!
Best wishes!
Thanks for a great video, Will! I learned more about hooking up a balancer and adjusting it. Like others have said, many are the videos that I have watched, and this one brings more clarity than I have seen prior to this. Thanks for your commitment to quality production.
I’m so proud of you how much you grown the past two years
Well done, very informative and understandable! Your really helping inform & educate and providing great value to the community! Kudos Will.
This is great. Thanks for doing the video. This guy knows batteries. He has a talent for explaining very complex battery information that can be easily understood. Thanks a bunch and keep up the great work. I subscribed!
You are an awesome teacher, this was one of the few videos like this I have ever watched end to end.
Great content buddy! I've been a subscriber from when you were just a few hundred subs, and I've watched your knowledge grow from teaching what you knew at the time until now. And I think It's great to have seen this and how quickly your channel is growing as a result from helping people as you are learning. The big key I believe, is that you are really helping people. And you are afraid to dive into the next best ting coming out in battery technology. (One thing I've learn't first hand though, don't ever take Chinese selling specs as factual, halve their specs at best lol, funny because It's true. EDIT: Not all, but usually if it is ridiculously cheap stuff).
It isn't that far off, that you will receive you 100K subs Trophy! Well done ahead of time, as It's coming, and sooner that I think! All of the best.
Colin.
I've been watching your videos and I must say that you do a very good job in introducing solar power to the beginner and providing a vast array of very interesting and thought provoking DIY projects that I'd like to dive into. Thanks for sharing your knowledge on this very interesting subject.
I have watched too many battery videos over the past few years.
This is probably the best I've seen. Well done young man 👍
Thank you!!!
@@WillProwse It's hard to believe how much your life has changed since you made this awesome video! I'm so proud of you, Will
I'm not even into this stuff but ended up watching the whole thing just out of respect for the amount of time and effort that was put into it as well as the knowledge gained, and how interesting and cool it is. What a great video.
Thank you!!!!
Not only are you very knowledgeable on this subject....you have very good teaching skills! Thank you Will for taking the time to explain this stuff so well....
The joy you have regrading batteries is contagious!
I watch videos here and there because soon I will build me a home system! THIS GUY, wow! He has it down Perfect 100% Spot-On! Thank you because this is what I will Start with!!
This channel is excellent. Top quality and really informative!
The Bob Ross of the art of solar. The only 'best' set of tutorials on the subject. He is a very good teacher with simple, concise and witty information.
I am impressed by your know how and maturity. The sky is the limit for you
This is probably the best battery tutorial I have ever seen. You are a very intelligent and articulate teacher and you should publish a booklet as a basic and concise battery manual.. Good work !
David Hawk Agee with you . I’m not all that smart and need a book and a video to help retain all that info. I just want a simple system for my RV so my wife and I can be more independent when we boondock.
Wonderfully informative!! Thanks so much for increasing my knowledge base, now I'll have to watch some more of your stuff!
I was mechanical with a little electrical. This guy is good. Thanks for a professional video with good advice and direction.
Dude, your videos are so helpful. I hear everyone in forums talking about this Will Prowse guy and I had no idea. You are the Czar of Solar.
This video only proves one thing..... I shoulda stayed in school!..... MAN!, You're an intelligent young man!.... RESPECT!!
Obi-Wan Kenobi,
Great instructional videos. May the force remain with you!
Thank you for all the hard work you put into these “M.I.T.” Quality Presentations for us ordinary RVers. TRULY AMAZING!
I have watched your videos before, but during this one, I knew I had to subscribe. So much useful information. Thank you!
my new favorite chanel. I just built a 24v 6000w inverter system in a custom trailer with 6 260w panels on the roof.
Wow that sounds like an awesome setup
what a great vid - extremely professional and informative
I can’t say how much I learned from the safety info and the extreme temperature info in the first five minutes. Wow. Well done.
thank you for doing an outstanding job of presenting this material sometimes you go a bit fast but i can always rewind !
I love your introduction. I live in Central California from may first to September 1 it will not fall below 90 and July 100+ so much for keeping them at 70 degrees.
If you have a basement or crawl space ,place the batteries on ground or and place an upside down cooler over it or build a styrofoam box around it. It will keep it cooler.
Donald McClellan mostly you don’t put them out in the sun. Like the earlier commenter indicated you want to make sure that they are in a cool area. It’s not typical for most people to sit out in that heat. So wherever you go take a temperature reading and it’s likely close to or just above the normal operating temperature in a planned or controlled environment.
Great presentation. I feel confident now. You have a gift of teaching my friend. This opens up new possibilities for me to try. Hell ya!!!
Will , another great video! This is the best that you have done so far . Really glad you broke it down to very simple instructions! Especially on the balancing wire thank you!
Wow. You are an EXCELLENT teacher. Everyone who teaches needs to watch your videos to help them with their teaching technique.
Great presentation. For marine use, or any, coat your terminals with silicone dielectric grease to seal out corrosion. If you don’t have that, then Vaseline will do.
Did use gun grease on the battery terminals in my sailboat and 5 years later they still looked like when brand new when I took out the batteries :)
You are killing it Will. Cheers.
Thank you. I’m so impressed at the clarity and systematic explanation you give that i’m trying it for my boat replacement system. Great!!!
This guy is amazing! Very smart and very good at communicating processes and procedures!
Can you please do a video about which cells you have used, and how to shop for cells? I'm planning on doing a 48v system.
I’m very interested in building my own solar battery you’re a lot of help I’m 80 years old so I’m a little slow but I enjoy your tapes tremendously thank you so much Leroy Warner
Good luck Leroy! (:
Probably go with lead acid. It will serve you for the remainder of your life
@@MrJhonnyJackson Verily going through shameful comments since using You tube; requested for improving quality in all properties of life; like doing, thinking, felling and even spiritually. Allah may keep you on straight way known as Serat-e-mustqeem.
Wow, you’re a great teacher - very detailed and obviously very knowledgeable - I’m ready to give solar a try - looks like fun. 👍
Excellent video, I had been searching all over to learn about charging with my truck alternator and you covered it and so much else too!
Love it. Really amazingly simple and professional. Definitely following. I see you do solar too, what solar setup would pair well with this battery system? And what charger and inverter....?
Great tutorial, thanks Will!
Can you talk a bit about hybrid charging options where the batteries will also get charged by grid / generator in addition to solar. Thanks!
Amazing video!!! Thank you for taking the time to make and and walk me through the steps at a beginner level.
I just subscribed, I have no need to build any of these projects but this guy is such a great teacher I want him on my list just in case I every want to work with solar or LiPo.
damn,i wish u was my teacher back in high school,AWESOME STUFF,love everything
Wish you ‘were’ my teacher.
how in the world did you learn all this stuff? i'm impressed
What a great service you're doing for us, thank you!
This gentleman explains things really really well. Thank you sir.
Lithium is the best. I like non combustible and I love the price. The way you explain it looks ez enough
The price he quotes in the video and top comment for that cell type and size is not realistic unless you are getting used or new old stock. For new lifepo4 cells of any size and capacity it will be more expensive than an equivalent new lico or limn (18650 3.7v nominal) etc. There are several other significant issues, oversimplifications, or omissions with this video. Lifepo4 is great if you work within it's parameters and use the right hardware. My 1.6kwh bank cost me $120 for the new old stock cells.
He’s wrong, it can still catch fire.
MrKinglyon2010 bullshit
@@seanmurray6684 false, those are the prices for new batteries, the price went up to $850 for this pack but that's only after his video giving a strong review of these batteries. These cells are simply made with older manufacturing techniques that have been refined for a longer time, the cells aren't as small or light as newer ones but the capacity and price is real for brand new product, you can find these kinds of cells in AliExpress, eBay, or even on several electric vehicle parts sites and he has a link to them both in the comments of this video and in his review video of these kinds of cells. You don't need used or NOS parts to get this price.
hello I am from Zimbabwe. Massive respect
Nice system ! Easy to monitor or replace individual cells . You have explained everything and answered related questions at the same time ! I'm very interested !
This was one of your best educational videos especially about the correct alternator
I'm learning about lithium batteries when I should be sleeping. Oh well, not the worst use of time.
You are a very good educator. Thank you very much.😁
This guy is really cool. Also what an amazing effective clear speaker. Not an easy thing to do in front of camera. No ums, ahs, like's and you knows. Two thumbs up!
Good pace, great energy (pun intended), very comprehensive and looks like fun to build. Woot woot, Will!
You can use any source (alternator included) if you use a permanent Protection Board. These usually contain a charge limiter as well as overdischarge/short circuit/high voltage/low voltage cutoff. This means charging might be slower than normal (depending on the charge limit of your Protection Board) but it will prevent damage from high-C charging as well as protecting your charge source from overcurrent situation.
Can you suggest a make of a protection board?
I never clicked on a video so fast!
Just one question: How do you know what the full voltage range is for each cell? Does it come with the cells when you buy them, if so how can you be sure that the cells have not degraded and that the ranges have changed since the cells were manufactured?
This information should be available from your battery supplier. One would hope for a datasheet for a given battery, but at the very least the information should be available on the seller's site. I wouldn't personally buy any expensive product like this without clear, published information. It's not only about the money or potentially damaging the cells, but also a matter of safety. If one doesn't understand how to use the cells within their specs, then there's no way to safely design a system.
TFS Will you are always so complete with your information. I have so much to absorb.
Great video! I use that very same blue device for my model airplanes. I mostly use LiPo, but I also use LiFe. You can change the battery chemistry type for the monitor from LiPo as seen on the screen on the left with black background to LiFe, and it will give you a more accurate percentage (shown on lower right) of the capacity remaining in the battery pack and per cell.
Keep doing what you do!!!
What do you think about Firefly AGM batteries ( carbon foam ) for extreme climates instead of heating
AGM are the worst battery. They are extremely sensitive to 14V charging because there is so little electrolyte. Even expensive MPPT chargers reset their float charge peramiters to 14.3 or 4V automatically... Which boil the electrolyte. This is death for AGMs.
This is the way any DIY'er on a budget should go, so this bank is good for about 1000 watts of panels and your recommended 40amp charge controller, but what if you need double the energy, say 4800wh, are those 60amp epever controllers just as good? I ask this as Im trying to decide between on of them or an SMB120 by electrodacus.
Do you decide?
Excellent video. You communicate a clear mastery of your material, extremely clearly. Thanks so much!
At this age, and I have watched my fair share of videos on youtube, this kid has his act together and for as long as this video is, its PERFECT to understand.
Great videos! Question: I live in Florida, and you mention that ANY battery will degrade if it's in a hot RV, and I think you mentioned 70 degrees. Dealing with cold weather is easy, you just stick the battery in a heated compartment. But what's the solution when the normal operating environment is hot, like 95 degrees?
For your next series Will can you go over building your own personal thorium nuclear reactor, lol
😂😂😂
Hahaha...they navy seals will be sent in to I invade his studio. While the secretly search for oil under his floor boards...🤣😂🤣😂
Nice try Osama.
From these videos I have learned that there is much more to know than I realized. I should start small, with a simple 12 volt system, and work my way up to bigger systems and higher voltages.
Back in 2009 we used to use that tape to fasten plexi glass windows in custom computers. We called it the 3M tape of the gods and taped a full sided computer to a glass window with four pieces like you used on the first set of LiFePo packs. Thanks for teaching solar to an old dude like me. I would have been like you in my youth with your opportunities today. Respect.
You should give live seminars!
I think he will do well too IF pick to talk on climate change ... One cannot but listen and agree.
how about a link to where you bought these cells?
An excellent tutorial for my current project! Many thanks and keep doing a great job!
I'm a new fan and very encouraged to learn from you.
Dude, I totally believe you are from the future.
Or at least you'll be at home there.
Where did you get these batteries? Can you add a link to where you got these batteries?

@@WillProwse I cannot find the same pretty white and green capped batteries as in the video on your website.
@@ikannunaplays I sourced them locally
@@ikannunaplays they are all pretty similar
DIY Solar Power with Will Prowse Yes, I noticed but I like the visual appeal of the ones showcased in the video and wanted to replicate that. Thanks for the reply
Holy Cow, I didn't even realize I wasn't subscribed....BUT now I am!!! Great Work Will!!!
You have a wealth of knowledge and I love your videos please keep them coming.
Where do you get the cells and busbars?
I had the same question - I thought the white cells are cute - assume suppliers are linked from the linked website in the description - found other, but not the cells in the video so far.
It's calb cells, you can find them in AliExpress or eBay as well as several electric vehicle supply sites, he also has a video on them, titled something like "cheapest lithium batteries on AliExpress" or something like that.
where did you purchase these cells i can't cant find anything close to 600$s for 2.4kwh
The cheapest new LiFePo4 batteries I can find are 32700 LitoKala LiFePO4 on AliExpress. 1kWh is about $146. Each battery is 6.5Ah at 3.2V (0.0208kWh) and sells for $3.052 when you buy 10+pcs. You will need 48 cells (~$150) for 1kWh. The LiPo 3.7V version is a bit cheaper but trickier to charge correctly and will lass fewer same depth of charge cycles.
thank you for your channel, its very informative and actually you reply to your viewers!
Excellent video, with clear walk through of how everything works! thanks! I'm going to try this with my old Prius nimh cells, still in their compression case, of course.
Great video Will, would you be interested in selling those batteries as a 24 V unit or 12 V pre-balanced, I would certainly buy one for my rig
of all the links in the description, not one relating to where to buy these cells.... wtaf?
Was great to watch this even though as you said it's outdated and better to use a good quality BSM ! It shows the basics and helps watcher understand what the BSM is doing for the and I think everyone should watch it for a great understanding of the basics and what or how the BSM is balancing the system! Thanks for the great video!
Very detailed. This is a beautiful, and complete test to build your own 12 or 24 V system.
Next video subject: Please explain why your twin brother Sheldon Cooper is SO mean and condescending compared to you :)
Your little 12 Volt setup actually looked VERY good. Don't knock yourself-you are VERY competent!
Thanks for the hard work you put into you videos.
My alternator powers a 30A DC input Lithium balance charger!
can you explain this further please
Honestly, I am not a math, nor science, nor electricity-understanding person, but you are so highly-watchable. I have been looking at the Titan because of you but now you have me looking at DIY and that makes me laugh.
Wow. Your videos are amazing. Somehow just enough information to get all the points across, but not too much.
Love all your videos! So much so I click every ad.
You have certainly learned the details. Good work.
Great video, great content. Awesome job. There is only 1 issue with this set up, the hose clamps. Over time the hose clamps will dig into the plastic battery case, I learned this the hard way. Battery acid EVERYWHERE. For people watching, just find a better way to mechanically connect the battery cases together. Maybe just put rubber between the case and the hose clamp.
Other than that perfect instructional video.
Thanks Will, super informative. Well presented. Looking forward to learning more.
Dude, you motivated me to "like and subscribe" for the first time. I have a background in engineering and like most, I was SURE that I was smarter than everyone on TH-cam, until now.....
