Dude you're my off-grid hero.

Your excitement is so moving, keep your enthusiasm going. I am so thrilled to see young people tackling technological challenges to improve the quality of life.

I'm mainly impressed with the young man with brain capacity to do something constructive with his life even if it's possibly only a hobby . I hope other young men and women consider him as a role model instead of the junk the main stream media pushes . I give you 4 thumbs up for constructive information !!! 👍👍👍👍 😎

William, again, you knocked it out of the park. Your Videos are fun to watch. Love your enthusiasm. Note to self. Stop touching your probes and battery terminals with live current. Your body will thank you 20 years down the road. God Bless You young man...

I love your honesty, it's rare nowadays your passion for what you do is amazing and I would like to thank you for your video's.... Smile Dwayne

The 'Will Prowse effect' that causes the price in battery stocks to jump up and down :P

I viewed this between 230pm and 330pm on Tuesday and Ebay only had 1 battery left at a decent price...while I was getting myself together,,,it sold....wow...

Ian Murdock [below] quotes 4 Ah per week self-discharge due to BMS. This is insane - my small solar system would lose several percent of its output just to keep a BMS warm? I still recommend careful bottom balancing prior to battery assembly when using LiFePO4 cells - we know from EVTV that quality LiFePO4 cells thereafter do not diverge in capacity, so no need for BMS parasitic drains that can actually unbalance the battery if no charger power available! Nevertheless, these batteries would be an ideal starter system for newbies. Thanks for testing them! Keep up the good work.

I truly will never tire of these videos

Will, An interesting tidbit of information that I learned about having these batteries hooked up to an isolator. My regular battery in my 2018 Ford Transit mid roof van started conking out on me. It was showing signs that it needed replacing. Little did I know that if I turned on the isolator the engine would start off of 2 of these valence batteries that I have running off a 190 watt solar panel that is running a Natures Head toilet, a 12v ICECO fridge and 2 MaxxAir fans. These batteries that you suggested have been a Godsend. Thank you for sharing your knowledge and education people like me about these types of things. You are truly a blessing. Have a great day!

I really like your shows, you explain things so well. I live in an RV and I'm going to put in solar and you have been so much help, because I am a total beginner. Thanks 😎💞

These are the same batteries that were used in the battery system, of the "Smith Newton" all electric box trucks, I think they said they used 96 of those batteries to power the truck!

I've never seen someone get so excited about a battery😂😂😂👍

Thank you for the update on the battery company. Most of the reviews are favorable.

I'm a mobility scooter user in Ireland also an experienced lifelong engineer. Respect Sir! And a big thank you.

cheap for LiFePO4 batteries! Maybe you just lucked out, getting 90% rated capacity from used batteries tho. With no guarantee, still makes it a hit and miss purchase. Happy you got some good ones. With 2000 cycles possible...you might still get a few years of good service in a solar system. cheers!

I have that same exact inverter I bought off Amazon sometime ago I’m thinking maybe five years ago or more,,, so far it works I haven’t used it heavy however I have used it usually to run my refrigerator

LOL i love the fact that you were like Am ordering more before i post the link... hahahaha Same thing crossed my mind

Just retired from 43 years as a PA. Most medical equipment with battery back up are plugged in 99% of the time. Thanks.

Just bought some for a van conversion hoping to end up with enough to run an induction cook top and a 12v fridge/freezer. This is the best video I have seen to get affordable power for a budget van build. The fact that they are used only makes me happier. I saw some that are damaged and the cords are cut it would be nice if you bought some of those and repaired them.

One video turned me into a fan. Nice work DIY Solar Power with Will Prowse. Well done without the usual fluff...super informative and I love the energy. Ive "Liked" the video and you've certainly earned my subscription. Look forward to seeing more. Peace!

Thank you for all of the videos you have posted. It’s a real help for those of us that don’t have an advanced degree in batteries lol. I’m sure you get pestered by people that are clueless and genuinely need assistance but they typically don’t understand that you have hundreds if not thousands of people all clamouring for your attention lol. Again thank you for helping out the solar/battery/off grid community by posting such excellent videos. Cheers mate

Love your channel! It's so nice to see all of these tests done by someone with a clearly impressive knowledge base. You're my hero

This reminds me of Cornelius kegs for brewing beer. When the soda industry stopped using them, the piled up collecting dust until someone realized they could be used for storing home brew. Suddenly you could not find them anymore.

More youtubers need to cut to the chase like you did in this video and the most important part was communicated well before the 9 mins was up. But your enthusiasm is infectious so I watched 'til the end. Nicely done. I'm tired of sifting through 20 minutes of blabber for 15 seconds of content. Keep it up!

Damn you Will, anything you test and get excited about, sells out and the price goes up!.

OMG when you turned it on and it beeped, I went into panic mode for a quick second because that's the exact sound my system makes when it shuts down, LOL

I just started watching your videos. They are very informative and fun to watch. Thanks so much.

Wow now that information truly helps me. I am in the first of a four step disease actually almost to the second phase this disease is slowly killing me without any chance of survival. Anyway I am doing all I can to learn solar and wind so I can start buying components to build our own solar system so my wife has her own power and doesn't have to rely on traditional power that's very expensive in our area actually the most expensive in the country so yes I am making sure we do break free of this thieves while I am able to do so. Your making this so much easier and better everybody wants to sell a bunch of crap and never actually help figure anything out myself. A great big thank you. I will be buying your book and watching every one of your videos. What a blessing!!

As I am working on going totally alternative enrgy for our place, I am not just going solar, but also wind with a savonous rotor generation system. But here is where I will get the most out of my power set up. I am converting everything I need her to be low voltage/low current systems. To me, it makes no sense to produce lowvoltage and then invert it to a higher voltage when many of our lighting and electronics actually run on low voltages and use a step down power supply to operate them. Example: computer tower. Most of the power requirements is pulloed by the power supply. The actual working voltages of a typical computer tower are 12v.d.c./5v.d.c./3v.d.c. and that is it! And it is all low current! So, to safely run it on a 12v system, I need voltage/current regulators to ensure that I have clean low voltages and stable low current. I can go on and on with a huge list, but I am sure that y'all get what I am saying. Oh yeah, you can buy 12/24v.d.c. refrigerator and or freezer system that only pull 200w. And they are more effecient than the 120/220v.a.c. systems and you can even do not just a chest freezer but a chest fridge too! Now, that is the way to go off grid. After all, why pull your system down with the amp pull of the inverter and then the extra amp pull by the power supplies that step down the voltage to the volts you are already producing from your system, right?

I really enjoy your shows. They are very informative and follow an understandable flow of logic. Great editing and content too!

Another Quality video Will! Thanks for all the work and detail you put into your videos!

And now the prices skyrocket.

I love your presentatIon THEN BOUIGHT THE AMPERETIME 200 as you suggested. I am right now testing it at 9600ft in the Rockies. I have watched many of your infos and love em all. Your a good teacher, gave me confidence to take on a bigger system. Thanks Joe

Building out my van in the next 18 months. Really want to do llithum ion. With around 1000 watts of solar. This is very encouraging!

Ok you got my subscription, I can learn quite a bit from this guy. I live in a Travel Trailer and want to hook up solar power on top.

Ok, I have an idea that I haven't heard before(but i'm sure someone has thought of it).. tell me if you think it's crazy. You know how RV's are starting to have larger battery banks, enough to run an a/c, provide heat, and power other large appliances. The company "advanced rv," is installing larger systems on mainly sprinters which can accomplish those tasks but it's super expensive to set up the high voltage generator on the engine and it's questionable on whether the engine should idle for longer periods to charge that type of system.. Of course, with enough money, anyone can do anything. People are really wanting to have off grid power which can power what they need... So, why not design a system with a stage 2 charging port on the side and a battery bank maybe half (or larger) of the size of an EV like a leaf? Sure, solar panels can help, but will not meed the demand of most that plug into shore power and spend tons of money per night.. There are more and more charging stations and many are free. For example, the one's at whole foods down by my house are free because they want people to shop while they charge.. Now, someone might say that those stations are only for EV or plug in hybrid.. That might be an issue for a 5th wheel or trailer.. however, one could stick a hybrid emblem on their class C or B van, and that might be enough to slip by and many may not care if your paying for the charge... or have the charge port connected to the tow vehicle which sends power to the trailer batteries.. Anyway, don't you think this might be the future of RV travel? You could be off grid for weeks, depending on power needs, in a class B or C with a full charge. In summary.. large battery bank.. 12 or 24Volt or larger, with stage 2 port which can plug into the thousands of stations over the country!!

Dude, great job of doubling the price of these used batteries! lol Wish I had a product for you to endorse

Thanks for the Tip. Used Battery and Used Solar panels. Your making it really cheap to go Solar back up for Emergency. Thanks Will.

Hey thanks for for the 'Heads up' I never thought about 2nd hand batteries. I live in Australia and have checked out 2nd hand "Standby" Batteries used by our telecommunication companies. They 'Retire' these batteries after 5 years. Expensive units usually on a trickle charge, sold off at a fraction of the cost with lots of life left in them. COOL!

Seems really good. Now all I need is someone to translate this to English for me. 😁 (What, I am new to this.)

Thank you for finding these. We aren't ready to purchase yet, but we'll be keeping our eye on these.

The reason that they have good capacities is they were used in a hospital they're not being deeply discharged on a daily basis

I work in a hospital Clinical Engineering department and these batteries are used in wireless roll-around computer carts used by nurses. The batteries are changed periodically regardless of how much life the battery has left.

Thank you for your video, audio, tutorial, clarity, simplistic & non condescending explanations 👍👍 Awesome video

Knew nothing about solar until I found your channel. thank you so much. Just 100 Watts on my minivan, but it's all I need so far.

$350 is dirt cheap ? This tells me, I'm going to need to wait a few years before I even consider Lithium.

Gosh you’re smart !!! I wish I knew all this stuff, makes my head spin 🥴

Wow. Great find. I'd spray with disenfectant. Lots of equipment has a lifespan but that doesnt mean its broken. You will get bored with them in a year or so anyways.

Hard to compete Generac advertisement: 7kW system starting at $2100. It uses natural gas which is the cheapest it's ever been. I live in California, near San Francisco, so losing power seems to be an everyday concern. But, love your videos and I am a subscriber. Keep up the good work.

A friend of mine told me about Valance brand used batteries on eBay. He bought one and uses it in a 100 Watt solar system for his amateur radio. Been eyeing them but likewise wasn't sure of their capacity. Thanks for the test. Checking out the eBay pages.

Thank you. I wish I understood more. My takeaway is this is a good brand to consider for batteries.

Thanks for sharing info on all this bro, I really appreciate it

Want an even cheaper option? Deep cycle marine batteries can be found at Walmart for under $100 each and give 120ah each. I have used these for 6 years. My first set lasted over 5 years

Dirty Secret: Manufacturing Them Leaves Massive Carbon Footprint. Once in operation, electric cars certainly reduce your carbon footprint, but making the lithium-ion batteries could emit 74% more CO2 than for conventional cars.

Price is now 300 for each of those batteries

`Great presentation I learned a lot I appreciate you.

Beat presentation on the subject I've seen. VERY well done .

Where i live there are several junk yards (auto salvage) that sell batteries, I've bought several over the years and never had an issue. WITHOUT CORE you can buy a truck battery for about 50 bucks, for another 5or 10 bucks you can up the warranty from 30 days to a year. Pretty safe bet.

Man how did you get so intelligent, your awesome, & seem to be 1 hell of a nice guy

I think the price of these used batteries has doubled now.

amazing!! thanks so much. i live in a 7x12 cargo trailer and i luv it!

So nice battery for all. U r right used batteries could not give full power backup.

You GOTTA KNOW You GOT ONE HELL OF A GREAT DEAL !!!!!!!!!!!!!! I just looked for them on ebay , cheapest I found $150 & up WAY UP !!$$!! Those batteries would almost cost as much as materials for My cabin !

Ahhhh Crap, the “Supply-n-Demand” effect has taken over and these used batteries have just skyrocketed in price...... Back to hydro usage.....

And everyone of these batteries in the world are now SOLD OUT

They are only used as a backupsystem when the mains go out, and need replacing every other year for safety reasons. Chances are they've never been used.

Good video!….I’ve been getting the Chinese AGM 100AH batteries (new) for $169…So that’s the best deal I have found so far👌

We get these all day at my job. From hospital carts. Might just save this video

Hello! Love the video! Just bought 2 of these batteries off of eBay for a little bit more than what you paid. I paid $386.84 with taxes and shipping so I still think I got a good deal. What kind of charging monitor is that you are using to test the battery capacity?

The question is: "what is cheap?"

Great result at 92%, espeicially with such an aggressive discharge rate.

Entertaining and encouraging. My goal is to make a generator for my refrigerator and lights and TV. I'll keep the heat and air on grid. Iwhenever I learn more I may make an on grid system but it definitely seems the quicker way to have a system pay for itself is just to remove a portion of the bill. I'll check your videos to learn why on grid systems that don't even have batteries are priced so much higher than parts to me make sense to do.

Thanks for all the great content. When it comes to battery storage systems have you ever looked at the Carbon Foam AGM technology from Firefly? I have a 400 AH FLA battery bank on a sailboat and looking to upgrade. Looks like my options, in descending order of costs, would be new lithium batteries, most likely Battlebornes, used Lithiums, such as the Valence batteries, or new Carbon Foam batteries from Firefly. From the literature available, it seems like the Carbon Foam batteries offer most of the lithium advantage at about half the cost. Plus, I would not have to change much of my existing charging system.

You’re Amazing! If I had a son I’d want him to be you!

Well you were right about used Valence batteries getting popular. I saw this video 10 months after you posted it. The cheapest USED Valence batteries I can find are all well over $300.

Great video in it's quality and information as well. For a guy like me who only uses solar on my RV to charge my 4 golf cart batteries the cost isn't worth buying anything but cheap lead acid, has worked for me since solar was invented.

Hospitals, ambulance, Any emergency response team, Fire Departments, can't afford a failure so they must change these regularly.

looks like they arent dirt cheap anymore. 500$ for a single battery.

Unfortunately, now asking $499 US.

Hospitals likely are required to replace the batteries based on date and hospital inspection requirements, not on how much they are used. They can not afford a failure in a critical event; but in non critical applications they likely have a lot of life left.

Ty Will... i have been wanting to switch from lead acid to lithium ion for some time, & i always seem to be a day late & a dollar short... your videos are always clear & informative, time saving, & $'s saving... thanks again...

Can i use a lithium iron car batteries from walmart for this project?

Do u know if I can use them to run my electric trolling motor for fishing

Great video. I'm guessing that these would be perfect for a sailboat solar installation, probably running 2× 330 watt panels??

These would be great to run a 12v fridge/freezer and a simple water pump for a shower/sink faucet in my camper. Also a 12v thermostat controlled water heater probe.

I do like this video. the batteries are, the last time I looked, around $600+ each. that's still cheaper than the 1K for a regular lithium battery. they also weigh around 25 pounds each, more or less, which is still way less than the 100+ pound regular battery. They also have the box, cables, bmi and thermostat and the regular battery has nothing.

To expensive and ebay criminals riping prices of 500$ nah i stick to gel ones

Will, (or others) hold on, are you sure they have internal over current protection? I read the Users Information and I didn't see that specifically. Is says they have over-voltage, over-temperature and over-discharge protection, but I don't see anything on over-current. Certainly seems to have the ability to shut down, and to measure current, so seems like it could do this, but does it? I have mine on 40A DC breakers, which would have blown instantly if I'd have done what you just did! I have FOUR in parallel and they trip the breakers if I pull much over 1,000 watts off the inverter. If the batteries were each supplying an equal share of the current this wouldn't happen. (unless the breakers aren't really 40A - note that 40A blade fuses do NOT blow) But that's not what happens, one battery apparently supplies most of the current, trips its breaker, this overburdens the other three and about two seconds later the other 3 trip. I can actually influence which one trips first by giving it a lower gauge wire! It's that "unstable". Buuuut, I'd love to find out they can really really handle their own overcurrent conditions by shutting off their own current flow! Maybe they'd even do it in a PWM fashion! Then I could feel safe to remove those breakers and easily power my induction stove to its full 1500W capacity.

Hey Will. I'm really enjoying your videos - love the enthusiasm. I have been looking at the Valence batteries. Have you played with the 138 Amp/Hr.version or their own BMS? What would be a good 3rd party BMS, if not????? Mucho Appreciado.

Brother your videos and info on products as well as power savings is great. Thanks for all that you do. Peace, Jim

Very cool, very informational! Thanks! And I’m guessing the reason you got great results is because as medical equipment, they were great quality to begin with.

All lithium is cheaper than lead acid in Europe!

your a lifesaver dude! Too bad that the prices went up and they are mostly out of stock. Hope you find more cheap batteries.

FYI quick look at the Valence 138Ah today 4-7-20 lowest ebay price I saw was about $400 with shipping and also much higher from some sellers!

Outstanding video! Out of curiosity...how much do these weigh in comparison to a lead-acid battery (group 24 size).

I like em' cuz they will go well with my Incredible Hulk briefs....

Very young clever Boy. Well done.

great info. If I was a hobbyist, I would try it out. i think I'm just getting the simple goal zero 400 or jackery 500 with 1-2 panels to keep it super simple
