Dielectric grease is a good thing to use to minimize changes in contact resistance over time. However, it is an insulator without any conductive elements. Combining conductive additives, such as graphite, would have marketing value, at best. I think you can just stick with standard dielectric grease (going to be cheaper) without any difference in performance.
Could this be a good fit to use for EVSE Charging that draws high wattage for long time? I wonder how it would sustain long draws of current say a basic one starts at 1476W for Plug-in Hybrid or 3600w to 8000w for Level 2/3?
At the moment, LTO technology isn't better than other lithiums besides it's charging characteristics. People who have used them in vehicles say they fall short of Lithium ion and Lifepo4 batteries for power density and discharge loads. They were used in buses in china a while back though.
So, is there 100ah on each section of 45 cells? and second question when you talk about the rectangular cells are the ones lifpo4? or also lithium titonate oxide?
There was meant to be 270amps (6x45amps) but as they were fake batteries it was only 120amps. All batteries are LTO - lithium titanate cells. Thanks...

Thanks for information,Sir i have a question I have this type of inverter which is in a problem when we throw the wapda grid to inverter it's automatic off,for fee minutes then on then off again again on off??
Hi Musharaf, I hope to add more videos in time including build information. There will also be supporting information available at my website tolnix.com in the future.
Hello Adam! I have the same unit as yours, i'm facing problems connecting to the unit via wifi. After reading the manual i thought that the unit comes with wifi integrated but it seems is not. Can you please tell me what's the part no. for that wifi dongle that you have and if it is inserted in the usb port of the inverter. Thanks in advance!
How reliable this Goodwe inverter and how good the build quality ? is it good ? compared to other brands like sma/victron/fronius. And I guess it's definitely better than any of the Voltronics and Growatt offerings
link to the fan you install under the inverter please? I just wired 2 120mm 12v PC fans on the top of mine to blow down and hooked up to a 10w panel on the shed roof that just runs the fans all day, has worked a treat but that one you've used look like it might be better.
@@edwardfletcher7790 in an enclosed system perhaps, on a wall off the side of your house, not so much, and, well, there's no room with a lot of models to mount fans under them without constructing ducting.
A good set of new genuine batteries set up from the start should be fine with a standard BMS, but non genuine or used cells, I'd use an active balancer every time.
The LTO battery chemistry is meant to last 20,000 plus cycles and a minimum of 10 years. Even if you cycled them twice a day.... 20,000/2=10,000. 10,000/365 days=27 years approximately before the batteries start to noticeably reduce their capacity. These were "meant" to be 40ah YinLong batteries. 40x2.3v=92wh per cell. These are extremely robust but i recommend getting a sample from your seller so you don't get fake batteries like i did. You CAN order direct from Yinlong grade A, B, and C cells.
I use a iCharge X6 battery charger discharger to test my Yinlong 66160 40A & 35A cells and I get satisfactory results . I use my LTO between 2.0-2.5V per cell.
@@jab376 oh, Lord! It s notoriously since many of them are serially connected. As we all know, in any serial connection, the whole string's performance is dramatically affected even if one only serial element is damaged, interrupted or has different (usually by internal structure alteration) parameters etc. It is alike silicon cells consisting any solar panel when the panel output is dramatically randomly affected during cloudy days by random shadows over only few cells of that panel's grid
Since these battery can take 10C, could you run these with a wind generator and instead of pumping excess wattage into a resistor at high wind, pump it into the battery since they can take 10C?
Absolutely, they can fast charge so will take all the sun you can give them and can be cycled around 20,000 plus times. Great for home solar storage, not so great for vehicles, ebikes, etc because to bulky for the power they hold.
I like the idea of safety and being in the northerncentral [MN] the temperature here gets cold so maybe if you didn't have room a nema 6 type waterproof enclosure outside could even be achieved. Maybe store them in a wine cooler for hot temps to thermoelectric cooling and keep the little monkey fingers away while also still being visible.
Yes, you could, it all depends. This system was meant to be around 10kw/h with approx 7-8kw/h useable. Unfortunately being ripped off with fake batteries gives me a total of around 5-6kw/h. You would need to calculate your appliance requirements first.
@@RedbackAviation thanks alot. Could, you tell us who sold you the fakes? And what you learned from your purchase experience? We are trying to learn from you.
@@jab376 You must be in America to use an Electric cooker and worry about a dryer. Most Aussie houses use Gas for cooking, especially off grid. Dryers aren't really necessary in the North of Australia as there are only 2 seasons (no Winter).
@@edwardfletcher7790 here is how to look at it in a simple way. Yinlong batteries are good otherwise many people will not recommend it. Too many people can not be that wrong.
Pretty average due to the low capacity of the batteries. I should have gone with 24S and not bought from a thief. Though the LTO chemistry allows me to cycle them multiple times a day without further degradation. This is definitely a huge strength of these batteries.
Technically it is not "outside" - it is in an outdoor area but has full protection from weather from any angle. Fully roofed, partially walled, out of the sun, rain and wind. Where I live, it doesn't have many weather extremes and stays moderate year-round.
I wonder why Tesla is not using these LTO cells with a cycle lifetime of at least 20.000? Seems they lose a 15% of charge if discharged but at a lifetime of 20.000 deep cycles this must be a good alternative. Pricing has gone down to and probably manufacturers of BMS's and Power Wall Equipment are upgrading software for customers changing to LTO. It probably does not take long for having a LTO Solar Charge Controller with a specific algorithm.
Basically it comes down to power density. A lithium ion battery can have over three times the energy as an LTO size-for-size. And for big fancy companies - being able to provide a nice neat smaller battery sells more than a bigger bulky battery.
Couldn;t you add two passive BMS units to the system to increase the flow of electricity to each bank. It seems to me that it is unlikely that the single passive BMS can move enough electricity to balance such large banks. If another one or two are hooked up at the same points on identical units the flow of electrons would be increased and they wouldn't know the difference. Those balance leads are tiny and don't move massive amounts of electrons around. An active BMS might help but I would bet more passive BMS units might also work. They don't have to cut off the balance current, but my guess more wired in couldn't hurt for extra protections.
There are plenty of different scenarios I could've done but didn't have time to experiment. The active BMS that I have now added works perfectly and constantly balances at one amp which the wire can handle. Once balanced, most cells are staying pretty close to each other.

Yes, it could have been made small but would not be strong. These LTO batteries have a low power density, especially in this shape. I have moved to rectangle 33ah Yinlong LTO. They are easier to work with. Yes, lifepo4 are much more compact for the energy, but still cycle life limited. I let the LTO batteries cycle multiple times a day without degradation. I would have to change that if used lifepo4 cells. So far so good. And I have plenty of room luckily 🙂
Yep I use dielectric grease all the time great stuff
Absolutely! I 100% agree - the stuff gets everywhere but does a brilliant job.
