    What about LiFePo?

  2. Siri Erieott on September 12, 2020 at 3:37 pm

    NiMH were in themselves not a block on electric car battery development. The ‘bottleneck’ was the patent restrictions imposed by the rights owners who ensured NiMH were NOT ALLOWED to be used on any vehicles except for remote control models but were available for any other use. This little bit of battery history detail is corrupt but the battery tech, NiMH developed by US car makers GM, who subsequently sold the rights in with legal restrictions imposed to prevent any competition to develop electric cars as competition to their ICE based industry & sales.

    Ps: Great simplified summaries, new sub.

    I want a electric self driving car, but I don’t want to buy it from a man who’s inherited fortune was made on apartheid, and who thinks that casualties to corona virus are acceptable so long as the economy keeps working.

  4. Jim Bougard on September 12, 2020 at 3:43 pm

    I appreciate the concept and agree that this will be revolutionary. However, you stated early in the video that this technology EXISTS. Kindly furnish a link to where I can purchase a super capacitor system, that I can use with my solar PV.

    We have learnt that there is no practical solution to a normal home usage (with less than 5kw usage). Lead acid not long lasting not financially viable.

    Lithium battery smart systems like powerwall & others (only available in limited countries) nor available in wide range at affordable prices (not practical at all).

    Supercapicitors still in Rnd phase without any pratical product availability (not anywhere close to near production for atleast 3 yrs practically).

    This is coming from someone who has a Solar Grid Tied PV system (where if I even go for lithium ion smart system it would be 10 times the cost of my entire PV installation..) which proves it’s not practical at all..

    well done man

  7. Brad Quinn on September 12, 2020 at 3:44 pm

    Part of what you skipped was the price of solar panels vs the price of batteries. Solar panels used to be really expensive when compared to batteries. So systems were sized with minimal solar panels and maximum battery storage. When the price of panel dropped the ratio reversed. Now you size your battery system just big enough to get you through the night and size the panel array large enough to recharge the batteries even on the worst day. For instance I typically use 15Kwhrs per day and my worst solar day is 3hrs. But when I built my system I assumed that those days would be cloudy so I would only get 33% output. 15KWhre X 3hrs X.33 means that I needed 15Kw of solar. Before MPPT controllers you could not run a small battery with a large array without the risk of charging the batteries too fast. But with MPPT came better charge rate controls. So now the charge controller can limit the rate of charge to prevent harming the batteries. Having excess panels means that you can have dump loads (heating water, compressing air, etc) engage once the batteries reach float voltage.

    Great info, that’s for showing….. thumbs up.

  9. electronzapdotcom on September 12, 2020 at 3:47 pm

    It is a really good time for DIY energy 🙂

  10. Ajay Vee on September 12, 2020 at 3:50 pm

    Thank you for you clear explanations. Have you reviewed the costs, benefits and availability of the liquid metal batteries being developed by Sadoway’s team at Ambri, Cambridge USA? They appear to have no flammability risk compared to lithium based batteries. See, but the website doesn’t say much about availability or cost. Is it still in development?

  11. oye lucky on September 12, 2020 at 3:53 pm

    Love your videos 😍
    Waiting lithum batteries Reaching price of Our current lead acid ones.. may be have to wait 10 to 15 years if i live

  12. Tony Rebeiro on September 12, 2020 at 3:53 pm

    Just wanted to let you know that Lead acid batteries (flooded type), in a stationary application, can be made to last in excess of 30 years, IF the appropriate charging and discharging protocols are used. And another very interesting aspect is that LA batteries can deliver, efficiency figures, close to 300%, again, if special charging methods are used. This was demonstrated by Nikolai Tesla, many years ago.

  13. Corley Kinnane on September 12, 2020 at 3:54 pm

    You said nothing about the most attractive battery in 2020, LiFePO4 for PV systems.

  14. David Fr on September 12, 2020 at 3:55 pm

    EXCELLENT VIDEO!!!!!! EXTREMELY HELPFUL!!!!!! I have been using Marine deep cell batteries that are about used up after 11yrs. I have been looking into whole-home energy systems for my completely off-grid small farm. Your video is helping me to decide which components and upgrades to use. THANK YOU – THANK YOU – THANK YOU!!!!!!!!!! Keep up the great videos. I use several Verticle Axis Wind Turbines (VAWT) and 2 smart flowers (solar). They are used for ALL in-house electrical, all pumps, all electrical fences, outdoor walk-in freezer, and walk-in refrigerator, shop electrical, etc…. GOD Bless

  15. Jedi Knight on September 12, 2020 at 3:55 pm

    once you buy a tesla battery your never reclaim your investment FACT.

    Love to see you walk thru Maxwell’s tech and anything tesla has done with them so far.

  18. John Hammond on September 12, 2020 at 3:58 pm

    I’ve had Solar PV panels for over 8 years and storage has always been the major problem

  19. Eric Seidel on September 12, 2020 at 3:59 pm

    useful video,

  20. Kris Vandermeulen on September 12, 2020 at 3:59 pm

    Good video, now I’m up to date… But what z about the liquid redux homebatteries like reflow?

  21. timkbir chico on September 12, 2020 at 4:00 pm

    Thanks. I have a 300ah 12 volt calcium battery with 400w solar input( in Andalucia), I believe we must all use less energy. I use, at peak consumption, +/- 250w. Unless using power tools of up to 900w when needed. I have had this battery for 3 years and it is still in very good condition. However I will change the system to lithium ion soon.

  22. Tom Hunter on September 12, 2020 at 4:01 pm

    I don’t get the pay back. In Germany electricity cost 0.36 $/Kwh and the power wall capacity 13.5 Kwh. 13.5 X 0.36 = $4.86 Thus the powerwall capacity is $4.86 worth of electricity in Germany but cost $3000.00. The payback barely works in Germany. How can it work in countries that have a low or normal price for electricity.

  23. Matthew Huszarik on September 12, 2020 at 4:01 pm

    Your graph of electricity demand X-axis is wrong. Peak demand the duck tail is from 5-9pm.

  24. John Bowcutt on September 12, 2020 at 4:02 pm

    Warning sun run solar big scammers

  25. Brian muckdee on September 12, 2020 at 4:03 pm

    I experience many power cuts I want to switch to solar power ,is it better to go off grid or tie in ? I have 5 AC units plus the usual domestic appliances

  26. Rohan Nagdeote on September 12, 2020 at 4:04 pm

    Hello bro I want to ask you which country you belong

  27. Stefan Weilhartner on September 12, 2020 at 4:05 pm

    super capacitors are also super expensive. a density of 100Wh/kg for a home battery is fine but the charge cycle life must be very high. that is important. because prices are coming down around 8% per year, there is really a revolution ahead of us.
    solid state battery tech will be an interesting step. the problem is, that they don’t deliver high power and fast charge times and that makes them unusable for cars until that is fixed. but for homes, even 2kW maximum power for charge and discharge is good enough for a lot of use cases.
    from 2020 on wards this is the new electric revolution with EVs, cheap solar and battery buffers at the energy source and energy destination to balance the grid

    who get’s the Carbon Credits?

  29. Christian Reinisch on September 12, 2020 at 4:09 pm

    Musk bought A123

  30. Brian Ballard on September 12, 2020 at 4:11 pm

    I am still waiting for a "Super Capacitor" system to be advertised in Australia for a small home or 40ft (12.2M) Catamaran…

  31. Guy Clements on September 12, 2020 at 4:12 pm

    Have already installed Maxwell capacitors at 3654 kilowatt-hours at 9 modules at 64 volts a piece at 414 super caps 2.7 volts a piece assembled by Maxwell

  32. timkbir chico on September 12, 2020 at 4:13 pm

    Oh yeah, and a top quality regulator/ charge controller.

  33. Dennis Jemison on September 12, 2020 at 4:14 pm

    Yep, I bought 3,312.00 Bucks worth of Lead Acid Crown CR-330 ah Batteries and I sure screwed up doing that. They are great batteries but NOT for my loads on my solar system. When the sun goes down, so DO Them Batteries. I just changed over to leaf gen 2 batteries 98 modules and never run out of power. Those leads will be used for a greenhouse with small loads. Can’t throw them away. Anyone who buys lead acid for solar is CRAZY!!! JMHO

  34. Aswin G Sharif on September 12, 2020 at 4:14 pm

    Where is lifepo4 and lithium titanate?? You need to update your great video !

  35. Bobby Shaftoe on September 12, 2020 at 4:15 pm

    Yeah, this guys does a great job of distilling the broad spectrum, of a topic like this, into short, actually informative vids. WELL DONE!

  36. David Lockett on September 12, 2020 at 4:18 pm

    Capacitors only hold a charge for a short period of time, and storage batteries are still uneconomical for home use and will probably remain that way for several years.

  37. Twopersons Walksalone on September 12, 2020 at 4:18 pm

    I got 8 yrs on my first set of lead acid batts. And I’m on 5 yrs with the second set, which needs replacing. I don’t think the lead acid batts are made the same anymore. They don’t seem to last as long. Very interested in this new super conductor tech. Want more info.

  38. Prof.Heinous on September 12, 2020 at 4:19 pm

    Great series

  39. PRTCGV on September 12, 2020 at 4:21 pm

    Very well researched and presented "timeline of events"!!! Kudos to you Sir. 🙂

  40. Ferenc Tóth on September 12, 2020 at 4:21 pm

    Nissan Leaf 2010 came with Li Ion Battery, and Tesla Roadster came only in 2011. So why do you say that Li Ion usage started with the Roadster and Elon?

  41. Davida Jones on September 12, 2020 at 4:22 pm

    All Toby Keith and all patriotic songs all day long … iHeart Radio Toby Keith channel or on any platform on … 07/04/2020 … spread the word!!!!!!

  42. yarpos on September 12, 2020 at 4:23 pm

    density/price is one aspect safety/reliability/longevity the other
    happily I have no motivation to rush in and can learn from the adventures of others

  43. James m on September 12, 2020 at 4:26 pm

    Where can you buy the super capacitors at email me back at

  44. Storm Strike on September 12, 2020 at 4:26 pm

    I’ve had deep cycle batteries last over 5 years

  45. Backjack31 on September 12, 2020 at 4:27 pm

    Wasn’t that supercapacitor revealed as a fake?

  46. Archangel on September 12, 2020 at 4:27 pm

    I learned that I’m to broke to even afford free energy 😔😄

  47. Jamsheed Writer on September 12, 2020 at 4:30 pm

    Nice information sir.
    I studied about super capacitors in 2011 the passing year of my bachelor’s degree in Electrical Engineering,
    But the query about a capacitor is that what if it gets heated up and exploded due to manufacturing fault??

  48. Michael Batchelder on September 12, 2020 at 4:31 pm

    Using Battle Born and some Li-ion batteries in my system. Been running for less than a year. Nice video covering different concepts.

  49. Orlando Racelis on September 12, 2020 at 4:32 pm

    thank you for this interesting video demo.

  50. SUSHOBHAN SARKAR on September 12, 2020 at 4:35 pm

    Can you clarify whether the formula used to find the stored energy for any battery i.e V*Ah is correct or not because the value for V (voltage) used is the nominal voltage of battery i.e 3.7v for li-ion, 12v for Pb acid batt. But isn’t it wrong because we can’t discharge a battery to zero volts, then V = 4.2 – 3.7 V for li ion and 14.4-11.1 V for Pb acid batt. Times Ah of the battery?
