Update: The BLS store is giving me a full refund for the issues I experienced with their LTO cells. They said that they made a mistake and the cells were not labeled correctly. They wanted me to remove the video, and I refused. I told them that this will be a lesson to ensure that it never happens again. I still do not understand why these problems happen so often with battery distributors. This has happened on numerous occasions w/ multiple suppliers. Hopefully my video will teach the other companies a lesson. Previously, I did like the BLS store, and I have bought some really nice cells from them in the past. I am glad that I was ripped off before my viewers were. Who knows how many people they sent these cells to. If you bought these cells, test them and return them if necessary. ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Does off-grid solar confuse you?

Thanks for the Vid and NOT Taking it down ! Such reviews are Lessons for vendors & customers too. Any frauds / misrepresentations intentional or not must be put into the open for everyone to know it is happening. Out of curiosity. Do the date codes match ? Production codes printed on the cells ?

[@catch22frubert]

​@@WillProwse Hey Will, I know you haven't done anything with LTO batteries for a long time now, but if you want real 45Ah grade A cells, you can get them from an American company called XS Power. They make a lot of extreme car audio batteries, and they used to have lots of Lead Acid batteries, but they have recently started offering rebranded Yinlong LTO cells and they also bought the intellectual property from the largest and best super capacitor company there was. I believe it was Maxwell or something close to that. They made 3000 farad super capacitors, which were very useful for extreme car audio since capacitors can charge and discharge almost instantly, and they can charge and discharge in low temperatures. LTO cells have lots of benefits for car audio too since you don't have to worry about the temperature as much as with Lifepo4. Plus, LTO's charge and discharge very quickly at high C rates. Thats perfect for car audio. Hence why they are being rebranded and sold by XS Power along with the 3,000 farad capacitors. Its a great combination to use the XS Power/ Yinlong LTO cells in combination with 2,000 to 3,000 farads of capacitors. So, if you want to try the 45 amp hour XS Power cells or their capacitors, I can say they are regarded as a top battery brand in the car audio space. Limitless Lithium is another big company that has really expensive high C rate Lithium batteries for extreme car audio. It would be extremely interesting if you did a high C Rate output challenge between the Yinlong cells, proper Grade A 45Ah XS Power LTO cells, Headway 38120HP Cells to represent high output Lifepo4 cells, and maybe 2 AGM Lead Acid batteries in parallel. Pit them all against each other in a showdown and a teardown. See who has the best high output cells in the consumer space. That would be incredibly interesting to me and about 100,000 other people who use Lithium batteries in high power car C audio builds

[@bertschramm7285]

Hello Will, there is an easy way to tighten the buss bars properly with no danger of damage to cell. first put a nut on the threads flush with the base of the cell, you do not need to put any torque on the nut. Then put a buss bar on, then add a second nut, when you want to tighten the buss bars, you use two wrenches and the inside nut is screwed to the outside (as if you wanted to take it off), and you tighten the outside nut, there will be no tension going into the cell, you are only locking the two nuts into the buss bar. In some cases, you may need thinner nuts.

I mean if I can get up to 6000 cycles then that's perfect, even after that I'll still have 80% capacity. Also the reason there is so many grade B cells is because the Chinese use the LTO on applications and probably are required to swop them out after a certain time period, this is especially true for medical and public transport applications. Instead of throwing them out they sell it to us. That's my theory. Thanks for the vids!

Cheers

[@Devin82m]

Hey thanks so much for the great videos, I just discovered your channel and website. I was wondering what system you would suggest for someone who wants to get their whole house completely on solar without sacraficing any usage. I bought a solar power setup from Iron Edison this summer, I haven't had time to install it, but it's supposed to be a 1.5 kw 12v system, we shall see, but I had to compromise at the time and bought 2 200 Ah AGMs, but now after watching your channel I see how easy it is to build LIFEPO4 packs. I previously built a small 10 Ah pack, but the instructions I was following were iffy and I barely got the thing built, works great with a roll up panel I have. Anyway, so you suggest 48 v? And since I will most likely need more than 4800 w, do you suggest a different BMS? (I see on your website you don't suggest the BMS you like pat 4800 w). My plan is to slowly build out a system a bit at a time, add battery packs here and there. But I want to make sure the skeleton of the system is ready to handle the growth, I live in the country in Idaho and we are on the grid. The system I have currently does have a charge controller that is multi chemistry, including LiFPO4, and would barely be enough to power my home office, I do ham radio too. I would like to buy very durable long lasting components and buy backups o put away in case... Any help is appreciated.

[@zero_kelvin_]

how do you get that graph with the voltage range? Is this software from the BMS? Thank you, love your videos.

[@bohenderson]

Hi William, I love to watch your videos. I have dabbled in Hybrid Power Systems for over 10 years. During this video you down play the value of LTO high C rate. And for solar power, I agree. However, on a personal note, I have a Bad Boy Buggy, which is basically a souped up 4x4 Golf Cart. It has 8 each 6V 200A-H Pb Acid batteries in series and pulls 500 Amps. If I could get 100A-H of Li batteries that could handle 500 Amps at a reasonable price, I would switch over. In this case LiFePO4 cannot handle the C rate that I need. LTO is the only way to go. The limiting factor seems to be the BMS. The one you showed is good for 100 Amps. So, just a side note here, LiFePO4 cannot handle all applications. Keep up the good work.

[@steveshea6148]

Interested in building an LTO pack for long distance ebike touring because of the high charge rate. The ability to travel 45 miles, potentially get a full charge off of any standard household outlet in 20-30 minutes while having lunch, and proceed is very practical for that use. Will need to pull it in a trailer though because of size and weight . Thanks for the video .

[@rdmevX]

Another thought I have on lto cells is even though their energy density is much less than nmc chemistry they can take one heck of a high C rate charge. Eventually I want to build a pack for a 50cc scooter converted to electric that I can go to DC fast charge sites and hopefully fill the pack in under 15 minutes.

What do you think about using 12vdc or HIV sound amplifiers in PV systems?

[@lvstofly]

Have you ever considered using the titonate cells as a safety for the other lithium cells in your system? If you run the solar panels to the titonate cells and use them to keep the others topped off and warm? Just a thought.

[@garycotz563]

Did you mention which BMS that is for 6S LTO? and does it include Active Balancing?

[@greensavant2573]

Can't wait for your review of the Elechive by ZeroBreeze. It is a 24v system BTW.

“Testing in freezing cold temperatures “.. That’s what I have been waiting for. Well done!

[@crazystuffproduction]

hes done a few

I purchased your book last year but as of now what is the best power supply unit like jackery, veti, etc? Also what the best solar panels to date! 100 watt's. Thank you !!

[@mattrowe1229]

what are those slim cells called that make up the blue block at end of video with the black tape around them, or are they the same titanate cells

Hey Will, why did you go with aluminium bus bars this time instead of copper? I did some research and it seems aluminium bus bars dissipate heat better. I only ask because I have 2 meters of copper gas pipe here I'm planning on using as bus bars.

You could also combine super capacitors inline with lithium and get the same benefit. Correct me if I'm wrong. Have you tested Anti-Gravity Car Batteries? Are they any good?

@WillProwse can I use a Victron ip22 or Victron Orion 30a to charge Yinlong cells?

[@laszlomolnar4786]

Hi ! I saw in one of your videos that you test several types of accumulators and cells. How many amperes can it be loaded with? There was LTO in the experiment. Your tester showed 500 amps. I'm looking for this video. Can you help me ? Thank you very much in advance.

[@frankligas2249]

Thanks for the video. You say this chemistry is good for Antarctica, but how about Mars? What would you recommend for a Mars solar station?

[@smartorder4997]

The reason you can most likely just to get grade B is that Grade A normally do not sell in retail pack. Normally if you want to get a Grade A cells you need to contact the battery manufacturer directly, and in China there are many recycle battery and they put it on Online retail sales (as recycle one has greater margin). But if you are buying so small amount I don't think you can get much response from manufacturer LTO battery also has very little demand from the customer market, so it makes it even harder to get a good one

Can you make a video on how to make a portable diy battery -solar-charging station for overland? I go to remote places and would like to build a system in the box that I can take out of my car and charge my electronics.

[@BriTube007]

Looks like a great application would be a van with a big alternator that is set up to use for downhill skiing, which is what I am working on at the moment. Cold temps, very high charge rates so you don't have to run the van for hours when charging. Frequent start and stop cycles when touring around etc. And thoughts on why there are so many B cells out there? Honda, Mitsubishi, bus manufacturers etc use piles of these cells. If any cells don't meet their stringent specs they hit the B market I expect.

[@Galaxy2Free]

Thinking about building a car starter battery with these cells. Would it be overcharging it to 2.88V for 5S configuration? Since I know the discharge characteristics of these cells not quite good below 2.4 volt.

[@Saleh.Al-Ghamdi]

Will can you remake this video again? I think many new solar panels are there sense last year video you made

[@voiceofinsight5811]

What battery type will you recommend for someone living all year round in a hot and humid climate?
