Great rebuttal to these misplaced comments. So many folks are quick to correct when they have partial information. I appreciate your thorough understanding and help clarifying these folks erroneous information.

Video summed up: Will: I have years of experience with various Battery chemistries, their charging cycles, cell degradation and have read into a ton of literature. Additionally I have tested countless different BMS and know exactly what to look out for. People with 5min google knowledge: „NO“

Finally. The trolls get called out by name and take a hit. Well done Will Prowse, well done.

Honestly, as a new guy to this stuff, I appreciated this video because it addresses some of the issues people bring up that I have not read in any literature. But they are self proclaimed experts. I don't have the knowledge to dismiss their claims so seeing this helps people like me remember that everyone thinks they're an expert until they meet a real one. Thanks Will.

Answered with logic and reason, not emotion. Well done.

The calmest "AHWWW HELL NO!!!!" i ever seen, keep up the good work and research you do for the rest of us.

This is the perfect level of 'face planting' that our society needs more of these days. You're not being outright mean or nasty, but nor are you subscribing to the overly gentle politically correct agenda that continues to allow people to remain misinformed and thus continue to misinform others. You're a beacon of light. Keep it up!

You are so kind. That was the most gracious debunk I have every witnessed. Thank you! Civility is not dead.

Love seeing guys that just got into this topic because of their e-scooters and new RVs pushing back on guys that have literally lived this specific topics for years. Keep it up Will!!!

Thank you for your patience, and thank you for sharing. I learn a lot from you and it comes across in your enthusiasm while you teach us. Thank you for all you do.

"Please Substantiate Your Claims With Evidence" - Will Prowse, September 2020 - Amen Will, amen!

I'm going to tell you strait up what I like about what you're doing. You have facts and you're not expressing an opinion, and when you do give an opinion, you say its an opinion. A fact can't be disputed. It stands on its own merits. I never argue with my opinion because my opinion is worthless. Only the facts matter. The worse thing someone can do is to try and provide credibility to their argument by telling me they are an EE. and they know what they are talking about. I will relish the opportunity to tell them they should seek compensation for their lack of an education. Disputing the manufactures recommendations and specifications isn't smart unless someone can show test data measurements that conflict with the manufactures data sheet. The only exception to this is UL laboratories safety recommendations, if there are any. They have the final word and shouldn't be ignored under any circumstances.

LOL. I’ve been using LiFePo batteries for 10+ years. You got it all solid. Keep cruising 😎👍

Your methods are sound, proven and consistent. The findings are easily repeatable, good scientific methods applied here. I trust your findings, as I have seen your earlier videos where you have honed your methods. You are my "go to guy" for allthings solar. Keep up the good work.

Hey Will, first of all: Really like your videos, how you explain things and bring the important bits and pieces to the viewer! As a doctorate student in the field of safety of lithium ion batteries, I can affirm that you do have a good understanding and structural approach on the topics. Built my own small solar farm (as a hobby the past weeks) and was lucky to find your channel, especially about some stuff where I needed more info on (MPPT vs PWM, real life data on inverters etc). For the C-rate topic: The rated nominal capacities for cells are measured for a certain current/C-rate, of course with a higher discharge current the capacity decreases slightly due to the DC-IR drop, but I think you also mentioned this. Keep it up, you're putting out great content and dont let those comments get you down!

wow, right off the top name-checking ignorant viewers. gotta love this guy. 😀

You’re getting so big, you’re gonna get a ton of “experts” chiming in. You’re an eccentric man which makes you so captivating and refreshing from the rest. Your methods and knowledge is sound.

Will you rock! The minute I saw your first video, I was like: THIS GUY HAS DONE HIS HOMEWORK AND CONTINUES TO DO HIS HOMEWORK! You are humble, funny, accurate, up front but also and more importantly HONEST! People who truly follow you get what you're about, enjoy all of your work, and appreciate what you're contributing. You've taught a lot. Keep up the good work.

I love the consistency in the testing methodology....my "go-to" for trusted reviews. Thanks for the great work!!

Will dont let the haters get to you when you get this big the bigger the haters

Guy who says the high voltage cut-off per cell should be 4.2v does not know the difference between an NMC lithium cell and LFP cell....

How Many you tubers call Out there commenters/subscribers? Gotta love this guy and how he is serious about what he does. No BS here! Keep it up Will!

I really like how your rebuttals are data driven and explained so well. No arrogance or anger on your part. Thank you for your videos. You have no idea how much they have helped me!!

Ignorance in a comment section? NEVER!!! 😂😆🤣

Thank you for all the great information you've given us. Keep up the well researched and accurate reviews !!!

Thank you for making this video. You have done a great job of providing useful and valuable information to your viewers who are interested in learning how to assemble solar systems with battery storage. There is no question that you know what you are doing and have put in the time and effort to learn every aspect of the chemistry as well as the safe and effective use of your tools and testing equipment. Keep up the good work and keep making great videos.

I love these videos. It's a nice way to keep people from falling for disinformation while giving the rest of us a refresher and deeper understanding of everything you've been studying and learning. Keep up the great work!

"Watch my beginner videos!" HAHAHA!!! Too good

The 55 dislikes on your video so far are the ones that got taken to school! Amazing job explaining and educating us with FACTS 👍✌😁

Thank you for being so informative. Being a significant amateur about electricity, I have found your videos quite helpful.

In my 30+ year career as an aircraft controls tech and then mechanical engineer and building automation the first thing you do is ignore anyone that starts off a comment with "In my 30+ year career...." 😉 Keep kicking ass and doing what you are doing (helping us all get a little less dumb). It is greatly appreciated.

I wouldn't ever question you. I'm not that smart, but I'm smart enough to know you are.

First: Thank you for your great work here on this channel! I learned a lot about LIFEPO4 and checked A LOT of facts from different sources! Your work is really great and don't worry about those comments.... It's usually the same all over the net! Please continue the great and very informative work of yours! thx a lot and greetings from Austria

Amazing Will. You do your fellow humans a great service with your committed, rigorous approach to testing. Thank you, thank you, thank you!

Will, you're proving that the saying, "a little knowledge is a dangerous thing" is alive and well. Your annoyance with the instant experts shines through in this video - good on you for responding quickly and effectively. Your videos are the best.

Will you saved me literally thousands. The links from your website helped me find a deal on used 250W panels, a pallet of 10 for about 20 cents a watt. They're shipping now and I'll let ya know how it goes after setup. Even if only half work that's an order of magnitude cheaper than renogy. Bought your book on amazon as a thank you for this and all the other good info. Will post a review when it arrives. Keep up the good work and thanks again, you're really making a positive difference for a lot of folks.

Will, thank you for reading all the comments. Even the bad ones ,blasted out of the water, teach those of us that wish to learn. You have been and will continue to be the best source for unbiased info on lithium batteries on the web

Dude, Love your videos. Respect you as a knowledgeable solar/battery expert. Keep on making videos and educating and enlightening us.

Thanks for your generous output. Cheers

Soooo frustrating when comments like those are made! I deal with messages and comments like that daily and I sympathize. Thanks for this video! Hopefully it inspires some to do more research before posting. Yea, 0.2C discharge rate for capacity testing is the standard for Li-ion chemistries and it’s not hard to learn that with a bit of reading.

Hi, your are spot on with what you are saying in this video and the processes you use to test these batteries. Some people confuse lithium with lead acid and even think all lithium chemistries are the same. Ps, I am an electronic engineering that designs commercially available chargers for all different battery chemistries, thus if I was wrong about this stuff I would be in big trouble. Keep up the good work 👍

Thanks for answering all the research questions we have while looking for our mobile 12v solar system. . Your easily understandable methods and teaching is what us non tech folks really need. Thanks a lot, well done.

Mahalo, I'm learning and appreciate your straight forward testing with pro and con. Totally trust your opinion. A few years ago, with wrong advice from a local solar dealer on setting up a small solar system, caused a fire in my bus. So now I do my research, double check, and remain cautious on any product on the market. Again appreciate your honesty, and knowledge on these elements and products via your testing.

consider doing these more often. I love reading the comment section and sometimes take my info from there because they speak with such 'authority', like they're in the know.

Never argue with Will. His knowledge is really good.

When watching (and enjoying) your educational videos I may only understand about 10% of what you are saying, but I have complete confidence in you. Clearly you know what you are talking about and, whenever I need to learn about solar charging and batteries, I turn to you first. Thank you, Will. Keep ‘em coming!

Will, Love your level headed responses. I get a lot of armchair quarterbacking on how to restore the Frying Pan Tower myself with most folks never putting their toes in the water or riding out on the tower any of the many hurricanes, I've been through. As a 100% off-grid location (just outside the USA off the coast of NC) I've had many years to learn what works and doesn't work. The best answer is to say what the truth is, and create a few canned cut-n-paste answers to the clearly foolish flamers, and ignore as best as you can :) You're doing great work! Keep it up! Richard

I love how calm he is talking down to people hahaha. Miss his voice and the long-ass streams he used to make, glad he is doing fine. Really smart guy and everyone should take his advice when it comes to lithium batteries.

Thanks for being one of the few that maintains their integrity, Will!

A lot of people make a confusion between chemistry of Lipo or LiIon with LiFe, also they got stocked in Lead Acid era! You're doing a great educational job too!

Will Prowse don't let those arm chair "professionals" stir you up. I have followed your videos for a couple of years now. Your love for solar and all that goes with it is second to none.

Hi Will - Nice video addressing this issue. I think some of the comments may be innocent in nature and wanting to learn, while others are made out of ignorance or even lazyness. There are so many different chemistries on the market now, it is naive to assume they all work the same. A common message I often give to my younger, less experienced engineers is READ THE DATASHEET. It is remarkable how many people disregard this basic information. Personally I really enjoy watching your videos and find them instructive. I particularly love it when you do a tear down and debunk the claims of some of these "fly by night" vendors. People seem to forget that if something is too good to be true, it usually is. Praise the good guys and call out the rats. Keep doing what your doing man, you are helping us all.

Break-in a battery? It's not an engine bro LOL

Will, I love your videos and your attitude, don't let anyone with less or No knowledge ruin your day. Thanks for your teachings.

I'll admit I don't know the first thing about ANYTHING you talk about. I watch because I see the passion you have for sharing your knowledge. Maybe one day it'll get through my think skull. There is nothing greater one can do in this world than to share knowledge.

This is one of my favorite videos, where everyone thinks they are an expert on social media and always have to be snarky about it, I love that you corrected them with the "facts" and "science", in such "anti-science", "anti-factual" or "alternate facts" times LOL thanks Will for your videos :)

You sir have the patience of a god.🤣

Thank you for this video. Responding to comments was an excellent education for us newbies. Loved it.

I like this guy more and more! Way to explain without being negative, that's more than most can accomplish. My old brain has learned a lot from you, thank you.

Lol. That was entertaining Wil! Keep making great instructional video’s for our enjoyment.

This was a good video, put them on blast LOL

Hey Will, I am still learning and I appreciate how level headed you are and I like that you respond to mis-information, Good job! I have also had troubles in the past when trying t oeducate some people who are "Hide-bound" in their thinking and will not accept new ideas and new concepts. Please keep it going and take care!.

Thank you will. I started to build my solar shed last year taking a little longer then expected trying to buy quality products but quality is more expensive. So thank you for sharing.

Good one Will. Throw it "nicely" straight back at em.

*Searches comments to see if the accusers have made any new comments* ...nope!

Nice Will, this is why I watch your work I trust your knowledge I'm a beginner and could tell the people in the comments were obviously talking about lead acid or didn't know what they were talking about I personally appreciate the amount of effort you go to to educate your subscribers on how to build, buy, and maintain a system safely for years to come. Thanks Will.

I thank you for sharing great info about batteries, you are an amazing person and we are all grateful to have you here to teach us. best

lol, "watch the beginner videos" - Burn!

Will, don't lett these idiots affect you. You have great knowledge of thees battery's and systems. keep up the good work with educating us. Tb

You're the most knowledgeable expert on lithium cells, solar and inverters I know of even 2 years later.

I’ve been subscribed for a while but just stumble on this one. Wish I’d seen it quite some time ago as it would’ve saved quite a bit of confusion over my first time charging and equalizing some new EVE cells. Learned a lot here. Great video.

Some people think speaker wires need to be "broken in", there's no hope I'm afraid.

These comments just go to prove that you can't fix stupid.

I been watching for over a year now, and you REALLY know your "stuff". I got interested in this topic because of one of your videos. Continued joy and success.

Hi Will Thx for the vid. Being a Complete beginner with solar is confusing with all the misdirection on the subject. Having someone thoroughly knowlegable doing beginner videos is great. A separate playlist for beginners is top shelf.

I was told you need to top up the electrolyte with some distilled water. :)

You may need to leave specific links to your 'training wheels' videos each time. You can lead a student to text books but you can't make them think...

I don’t know why anyone would question Will’s battery Prowess! Your presentation and knowledge is obviously NOT superficial. Keep it up Will.

Thanks mate ! I learn so much from your videos over the years and always appreciate how you stick to the facts.Cheers Graham

You tell them my friend.

Class dismissed!

Absolutely the best info out there. Thank you for your time posting these videos!!!!

Hey Will, just for your readers (not that they will really care what I have to say) I sent your links to our CTO (solar power company) and he gives you five stars, "really smart". I have worked with this CTO for over 10 years and trust his input and evaluation. You are golden.

Will, where are you!!! Its been a month and i don't mean to be a slave driver but i miss the content from this channel

This video feels like an angry dad talking to his kids and he is very disappointed.

Excellent job Will. I have watched all of your videos that I can find and have just ordered my first set of 8 batteries. Thanks you for all your had work. You have saved me thousands of dollars.

Hey Will, I'm one of your forum members who bought the 280ah cells for $482 to my door from alibaba, (Xuba web site). I learned how to setup a lifepo4 battery by actually following your build guide lines carefully and my battery works great, so far, I;ve only been working on it for a few weeks. Your information is right on if you read it carefully. If there are any confusing parts of the assembly, testing and programming the forum is a big help. Setting up the BMS program is a little tricky but that is because of the poor documentation of the BMS ... it takes a little trial and error to optimize for the way I want to use it. (give up a little capacity for more charge cycles). Anyway you're a great teacher and we appreciate your hard work. jjb (aka ...tomtilly)

Lol.... all the Google University graduates came out on that video.

Hey Will, thank you for all the FREE knowledge and information you share with us! I would suggest those who are critical should start watching your videos and LEARN before commenting.

I’ve been in electronics and various battery types for years. You nailed it! Well done.

I appreciate the beginner videos linked. I only started watching your videos lately and didn’t know where to start. You should link them in all your videos.

Will, thanks for all your work making these videos. I went from not knowing anything about lifepo4 to being able to build my 12v 400ah battery bank. Pretty much souly on watching your videos. Thanks again.

Hi Will and thanks for all your great test videos, they did contribute inspiration for my song writing...

You have always been impressive by your knowledge, presentation and personality.

Will, thanks for all the testing and valuable info you provide. I appreciate it.

Great work. I am thankful for you

OMG, Will great video! Your videos always have passion which makes me watch but this one was spectacular. Great work!

So many can't read and comprehend information. You put so much into finding the correct information.
