Aquion Energy Salt Water Batteries

100 Comments



Hi, this is Amy from the altE Store. I wanted
to show you an exciting new deep cycle battery technology. They are the Aquion Energy salt
water batteries. Yes, you heard right, salt water instead of lead acid. Aquion Energy
batteries are safe, non-toxic, and long lasting. First a little background on how batteries
work. A battery is made up of multiple metal plates forming the positive cathode and the
negative anode. They have an insulating separator between them, and are immersed in an electrolyte
solution. When using the energy from a battery, and therefore discharging it, a chemical reaction
occurs, creating an imbalance of electrons, causing the flow of electrons from the anode
to the cathode to try to restore balance. This is the flow of electricity. As a battery
discharges, the anode and cathode plates become more chemically alike, the electrolyte becomes
weaker , and the voltage drops. To charge the battery back up, the process is reversed.
In a lead acid battery, the plates are made of lead (often lead dioxide on the positive
plates and pure lead on the negative plates) and the electrolyte is sulfuric acid diluted
in water. Aquion batteries are instead made of carbon, cotton, salt water, and Manganese
Oxide. Manganese Oxide is the 10th most common element on earth, and is found in soil, in
lakes, and on the ocean floor. All of these materials are non-toxic and safe, unlike the
ingredients in lead acid batteries. Aquion Energy batteries are the only cradle to cradle
energy storage product on the market – certified proving to be safe for the environment from
creation to recycling. So, let’s take a closer look at the battery
itself. It comes prewired as a 48 Volt stack. The S30-0080 stack is being renamed to the
Aspen 48S-2.2. The 48 means 48V nominal voltage, the S is a reference to “single unit”,
formerly known as a stack, and the 2.2 equals 2.2 kWh nominal energy
at a 10 hour charge, 20 hour discharge rate. They have H4 connectors for easy wiring. You
simply buy H4 extension cable to wire them to a combiner box, just like you do with solar
panels. Multiple stacks can be wired together in parallel. Unlike lead acid batteries, you
can wire as many batteries in parallel as you need. With lead acid batteries, wiring
multiple strings in parallel can result in unequal charging and discharging, shortening
the life of your batteries. Aquion batteries self-balance the charge, so if one battery
is at a higher voltage than the other, they will even each other out with no negative
impact. Depending on how fast you charge and discharge
them, each stack has about 48 Amp hours for about twenty two hundred watt hours of capacity.
So if you need 22 kilowatt hours of energy, you would wire 10 stacks together in parallel,
usually using a combiner box so each stack has its own breaker.
The Aquion batteries are also available pre-wired in groups of 12 stacks for a module. The M110-LS83
module is being renamed to Aspen 48M-25.9. The 48 again means 48V nominal voltage, the
M is a reference to “multiple units”, formerly known as module, and 25.9 equals
25.9 kWh energy at a 10 hour charge, 20 hour discharge rate. If you need more energy
than that, you can wire multiple modules together to grow up to utility size storage. Here’s a few more cool things about the
Aquion battery. Due to its design, it can be discharged down to completely empty, with
no harm. It can be regularly cycled down to 90% depth of discharge, unlike a lead acid
battery that doesn’t want to go below 50% depth of discharge (or DoD). For example,
if you discharge a lead acid battery to 50% DoD every day, that will give you 1500 cycles,
or 1500 days, just over 4 years. An Aquion battery can be discharged to 90% DoD for about
3500 cycles, that’s about 9 ½ years. As a result, you can use a smaller battery bank with Aquion
than with lead batteries, since you can use more of the stored energy from it, and it
will still outlive the lead acid battery bank. A few important things to note about the Aquions.
One is that they do not like to be charged or discharged quickly. Each battery stack
should never have to handle more than 17A, the lower the better. As you can see by this
graph, the capacity of the battery decreases the harder you hit it with current, so the
battery is half the size if you hit it at 10A rather than at 2A. Aquion recommends you do not draw more than
14.1 amps per stack. At 48V, that is 677W. So if you have a very high draw load, like
motors or pumps, you may need to oversize the battery bank to handle it, or stay with
the more traditional lead acid batteries. The second is that while the operating temperature
is fairly wide , 23F – 104F, Aquion saltwater batteries do freeze at 14F.
You can thaw them and they will still work, but there’s a good chance that the capacity will
be affected. A simple enclosure should be enough to prevent the battery temperature
to go below 23F. The way you size an Aquion battery bank is
a little different than sizing a lead acid bank, because you have to be sure to take
the charge and discharge current into account. Let’s use the example of: 4kWh x 3 days=12kWh storage total needed. Charging via solar during the day will be
across 8 hours, and using the power throughout the day and night will be about 20 hours.
So we look at the energy capacity table from Aquion, and we see that if we charge for 8
hours and discharge for 20 hours, each stack of Aquion batteries can hold 2,046 watt hours
of energy. Since we calculated that we need 12kWh of energy, we divide that
by the 2,046 watt hours which gives us 5.8. So we round up to needing 6 stacks to store
enough energy for our needs. But now we have one more step. We need to
make sure that 6 stacks wired in parallel can handle the current draw from the inverter
when we use that energy. While designing the solar system and evaluating our needs, we
determined that the highest draw of the loads will be 4800 watts to power our fridge, well
pump, tools, etc. So 4800 watts divided by 677W max recommended draw=7 stacks. So you
see why we need to do this with 2 steps. Six stacks had enough storage, but we need a 7th
stack to help distribute the load across the battery bank, to not draw too much from each stack. If we didn’t have a high draw on our load, then we wouldn’t have had to add that extra stack. So, to summarize, Aquion Energy batteries
are safe and non-toxic. Their ability to handle deep depth of discharge allows you to use
a smaller battery bank while enjoying a longer battery life. While they aren’t ideal for
very high wattage loads, or extreme temperatures, they are a great battery for every-day off
grid living and back-up power. Contact us if you’d like help designing a system for yourself. I hope this was helpful, if so give us a like and a share, and be sure to subscribe to our altestore

    Good news. Aquion has reemerged from bankruptcy. http://blog.aquionenergy.com/aquion-energy-return-to-production-in-2018

  2. Smart Producer says:

    nice information………….
    thanks,,,,,,,,,,

  3. zyxwvutsrqponmlkh says:

    What's the cost per kwh like? Also your hair is too big.

  4. Konstruktivist Neo says:

    This is a much weaker version of the lead acid battery, and not even close to the energy density of the lithium-ion cells. This is good only for Mickey mouse science experiments in a classroom. The discharge rate is very low, unusable in cold weather – thus the reason why no industry never produced or needed it.

  5. Sigvar says:

    Interesting mix of comments.
    Nice to see you will be getting back to it. I love this technology and I hope to see it cropping up all over the place!

  6. Jay Graham says:

    Can the battery bank be laid on it's side to spread out weight distribution for mobile application? This looks great for a stationary application. I live in a RV completely off grid except for water.

  7. David Underwood says:

    what is this guy talking about?

  8. SafuanMohamad says:

    her eye like aliens

  9. Andre Martel says:

    If you use a super capacitor batteries in parallel with your system. It will help with the surges and the spikes. At the same time you get a rapid recovery since only the Super Cars are drained.

  10. Electric Poliville says:

    nothing is designed for a 48 volt system no wonder they went backrupt

  11. Smattless says:

    1000$ no wonder they went bankrupt.

  12. Emir Muhedinovic says:

    And price is secret ? Teaser video?

  13. Zymondo says:

    Why don't they ever mention the PRICE !?!?!?

  14. Susan Stone Salas says:

    When will the batteries be available for sale?

  15. Pete Lorenzo says:

    why does it cost so much if the batteries are made from common materials? it says right on your website you can't provide support or warranty for past sales. your warranty is worthless if you can't show you'll back your customers huge investments. finish going out of business so you can stop raping your customers.

  16. AWPS Renewable Energy, LTD says:

    They are out of bankruptcy. But they are saying they would not support products that are already in the market. They will not honor warranties and the architecture of the new offering will be different from the legacy product. Any opinions or thoughts?

  17. jon b says:

    I have had a lead acid battery in my car , bleach in my cupboard , and all sorts of dangerous liquids in my basement like varnish etc. Suprising im still alive. Because i limit my exposure to these toxic things. Just like everyone does.

    Btw this is a gimmick. And judging by the prices of the company from before. It was a get rich quick scam with good marketing.

  20. woodsman forlife says:

    VERY interesting!
    Price please!

  21. David Forster says:

    Why so expensive? apparently made out of everyday easy to find common materials…… Given this, a stack should only be a few hundred bucks! I dont get it……. Better off selling the stack in pieces in a kit form – that way all you have to warranty is the materials. A few hundred bucks, and we put it together ourselves and fill with salt water. If Aquion is concerned about their financial future they could say that once pieced together by an enthusiast, novice, prepper etc the warranty becomes void – wash their hands of it. Let us work with it, improve it, make our own 12v & 24v power banks etc.. Imagine the online community that would form, full of ideas if this was to happen.

    Salt water? So what are they doing to take care of the chlorine gas these are generating?

  24. Mico says:

    I have never seen a more informative ad from a company that just explained to everyone why not to buy their product. It freezes in winter, it requires multiple "stacks" for "regular" usage, its way too bulky, and you can only use 1/3 of your entire battery capacity.

  25. Robert Anderson says:

    I don't have a grand laying around to buy 1 of these battery's with

  26. GrapSorz says:

    so. you did not manage to get to market?

  27. kevin g says:

    What is the price per battery

  28. Rommel Balacanao says:

    Is this compatible to use on my solar panel system with SolaX hybrid inverter? Please kindly let me know if you can that would be great of help.
    Regards,
    ROMMEL

  29. Stephen Dickens says:

    Are you kidding me, why not make a battery that uses only water, supplies power for years and uses no salt, and dont even need recharging, after all I did, its in my videos. But then thats how I know the battery industry is just another scam like most big business, which says oh were working on a better long lasting battery for you, when such a battery has already been around for ages.

  30. Derek Simenac says:

    Capacitors would prevent the need for an extra stack to handle load

  31. keith freeman says:

    I have it in mind, a device that would/could power a large house boat. The "batteries" would be in the salt water and would produce power. Two different metal plates with salt water flowing through, i.e. never ending electrolyte. PVC piping outer covering/housing, slung under the boat or built in to the pontoons.

  32. aeridyne says:

    Seems a lot of people are motivated mostly by price, and I can't entirely disagree as I sit here today considering getting a ton of laptop battery packs that I am familiar with and making my own diy powerwall. What I love about these aquion batteries though is I don't want lithium or lead acid or any other harmful pos battery in my house, or even in any of my structures outdoors really, because they are inherently hazardous. If you could make these for the same numbers close to a powerwall 2 I'd be sold if I could afford it. I don't care that it takes up more space, because it's actually SAFE. I've been waiting and hoping that they succeed with this battery technology, it's fantastic and if the human race didn't have their collective heads way up their behinds imo we would all want technology like this. Easy to recycle, harmless for safety and far more sustainable materials for construction.

  33. Lute Scrat says:

    price… please

  34. Alrukitaf says:

    Good luck aquion. Tough world out there, but I think this one’ll emerge a winner! Salt water as electrolyte. Manganese dioxide. Cotton. Voila. Sounds almost too good to be true. I wanna get me some.

  35. Drew Hurst says:

    Good green tech

  36. The Cow Conspiracy says:

    You avoid the matter of cost per stack…

  37. KNOWLEDGEHUNTERboy says:

    Can you convert your battery into thin film salt battery?

  38. Dean of the Tower says:

    :thumbs up:

  39. فهد الشايع says:

    This system excellent if you manage the cost of the batteries plus I'd like to know more about the number of solar panels needed for 3kwt with your idea

  40. Theodoros says:

    Prefer low current translates to "have very low power density" and this should be clearly stated. This is one hell of a drawback btw.

  41. Doug Penhall says:

    2:49 … Wrong… ALL BATTERIES WILL BALANCE WHEN CONNECTED IN PARALLEL. It's batteries that are connected in series that will become imbalanced.

    It is absolutely 100% impossible for two batteries connected in parallel to have a different voltage, and therefor a different charge. The batteries don't even have to have the same capacity in order to be properly charged in parallel.

  42. joandar1 says:

    Just been to your web site and looked at Lithium Battery. I can not see where on the page where the Battery is advertised on the specs and so forth any mention of a warranty. $950 all but for one 12 volt, 100Ah battery and NO WARRANTY, come on please. John.

  43. Josh Duncan says:

    how many stacks would you need to fully power a 30 amp rv for boondocking

  44. Peter Holman says:

    The saltwater batteries are designed for 48 volts but my system is 24 volts. Is there a solution?

  45. Ian Endangan says:

    Since you also sell small solar panels, it is logical to introduce a portable saltwater batteries (40aAh tops) to introduce the technology to the market. Here in the Philippines we have access to portable saltwater batteries with an led bulb and extra magnesium terminals.

  46. Victor Rodriguez says:

    Ok so what the weight on one those things? How does it get drop shipped?

  47. Theodore Bowers says:

    Wow this woman did an excellent job she narrated very very well she didn't seem like a jerk and she actually seemed like she knew what she was talking about for a change well-done lady

    Complete Kiwi Bullshit!

  49. Ryan Davis says:

    I can imagine 8ft tall battery in everyones backyard solar pannels on roof. D-i-y huge salt battery safe-ish and it kills the weeds

  50. sam guapo says:

    @altE would be nice if you had videos comparing all the other batteries side by side esp. for residential solar use.

  51. Matt Dathew says:

    pretty cool

  52. coydog52 says:

    where can I buy your batteries ?

  53. Asfand khan says:

    Please price

  54. Erik Åslund says:

    Mn is an element and so is O, MnO isn't.

    C-rating on batteries is the times per hour a full charge or discharge would be possible at that rate, a 20 hour discharge from full to empty is 0.05C, NOT 20C. 20C discharge from full to empty takes 3 minutes. A 10 hour full charge is 0.1C and so on.

    There's absolutely no problem to connect how many lead-acid batteries you want in parallel if they have the same nominal voltage, and roughly the same voltage when they get connected. You can treat them as one bigger battery, just adding their individual Ah for the total capacity. That works with lead-acid for exact the same reason it works with "salt water"-batteries.

    Why are values given for a 30 hour complete charge and discharge cycle on batteries marketed for solar power storage? What celestial body are they intended to be used on? Not Earth, we have 24 hours a day, our moon has almost a month, and Mars has less than 25 hours.

    Where to buy one in Australia?? Any open patents available, anyone tried to diy?

  62. Jody Ahlih says:

    Why isn't this working in harmony with the sea to get salt water battery power? In this case wouldn't the sea be the biggest battery what there is?

  63. John Titor says:

    i like the technology but the price sucks. good thing i'm a chemical engineering student that goes to PITT. I will copy this technology and make my own. since the raw material are so cheap. For personal use of course.

  64. justjohnny05 says:

    Does Jules Verne get the credit for this? This is how Nemo powered the Nautilus salt water + magnesium from the ocean floor.

  65. hummus shotgun says:

    where is the technology that reveals how they really work i never found anything that actually explains how the plates wont corrode in the cells

  66. Fernando Ortiz says:

    Hello, Any updates on your company's goals and plans for 2018?

  67. Sriram Bhagavatula says:

    the high range seems to be just 40 Centigrade, in Asia many countries have power shortage and have temperatures above 40 C , for almost half of the year. A better solution is very useful

  68. Maz mirzakhani says:

    Looked up the Spec 1500 KG for 26 kwh power…meaning the power density is 18 wh/kg that is too low…

  69. Colt Spiller says:

    I wonder if they went bankrupt, because of the cost of shipping? These batteries are very bulky and heavy! I wonder if they could just ship them without the electrolyte solution, and have the customer add it when they get them. It is just salt water, no need to ship that much unnecessary weight.

    thank u …any 12 volt systems.. how much is one battery…God bless all u do…a nice battery system..

  74. dobson777a says:

    From what I can tell Greenrock has taken over.

    The problem with these batteries is the low surge currents. They are on #10 wire. At 48v you need 100's of amps to start bigger loads at 240vac. What limitations do you have for running HVAC or clothes dryers?

    This presentation is very similar makes me wonder if they bought out Aquion. Watch "GREENROCK Webinar – New Generation of Saltwater Batteries" on YouTube

  76. Tidwell says:

    i can make this battery for the fraction of the price

  77. Quinn Montana says:

    It's not "cotton" if it's "synthetic cotton." I don't trust this group from the beginning: only cotton, which they show a picture of, is actually cotton, anything else is polyester or whatever. Misreprentation right off the bat is not a good sign.

  78. Kenn Hepner says:

    It would appear they are gone again.

  79. David Hamlin says:

    Not good for camping you should
    Try to make them smaller so people camping could use them

  80. Eric Kosak says:

    If you have motors or compressors you do not necessarily need a bigger battery bank if you combine it with a balanced capacitor bank.

  81. Cat Cat says:

    Whats the price of 1kwh of these vs acid batteris? Sounds to me that its only a marketing presentation as usual.

  82. William Smith says:

    Saline-and-carbon technology is so safe and simple that the price should be quite low, and yet we never even hear about it in the MSM. Imagine if large, low-cost saline batteries became as ubiquitous as air-conditioners outside everyone's home. The disruption to the fossil-fuel industry would be enormous. Something's going on, here. Maybe financial sabotage by investors? I don't trust anything Bill Gates does.

    Wow smart and pretty 🙂

  86. Amachetay Cybo says:

    That's pretty awesome man I was actually fixing to make a homemade Earth battery myself so this is awesome to see somebody finally made these and public about it is actually a professional company and it nit just some random one video that doesn't even give you enough information at times 😉

  87. Alrukitaf says:

    I’m amazed that this hasn’t taken off. We don’t have enough lithium in the world to use tesla batteries in the home. Concentrated salt water is in abundance in the sea. Maybe governments worldwide should look into this and invest. A word of caution: sometimes it’s a rip-off and some people fleece the public. Not saying in this case, but we cannot be certain until verified by several independent sources. It wouldn’t be the first time someone obtained money under false pretences.

  94. Ray Satterfield says:

    any update on this battery?

  95. movax20h says:

    Can't buy them anymore. What were the prices for them?

  96. movax20h says:

    3900 cycles at 80% DoD is pretty good and very competitive with LiFePO4, I wish there was more info on these cells. To what initial capacity are the cycle life measurements taken?

  97. Canadianhonkindiesel says:

    I guess this product fizzled out! None of the links work.

  98. ferkemall says:

    Problem with modern tech is like the old lead acid plates they used to be good lead then the tech boys made the plates really thin so they did not last so long ,i expect soon if not alreadt they will just plate some metal with some lead so the life gets cuts short = when it dont work anymore buy another one right !

  99. chas marischen says:

    You could give a price. Just say; as of today, or at this taping, it cost $X.

  100. p caetano says:

    hmm there is a huge area that could be used as a battery , aka ocean .
