LSP ? LYP ? actally TS is not more exist now. See http://www.chinesestock.org/show.aspx?id=118656&cid=28 , Winston are busy on fighting with the most wealthy guy in Hongkong,Li Ka-shing,who was his biggest investor, and TS battery changed brand name into "Winston battery" too. see http://www.thunder-sky.com/home_en.asp , We are glad to see this BIG war in field of EV.
Because Mr Winston Chung foucs on cheating money from HK exchange market,no one take serious with his battery technology and his engineer,their battery quality is worse and worse, One of TS engineer quit and come to CHL end of last year. He told me that LSP,LYP is actually another name of LFP,nothing change....
I don't believe!
This farce already occured more than months and everyone in field of china EV knows it.
http://www.chinesestock.org is a official website, it is not a bamboo telegraph...
You may confirm from TS website too.... they change name and logo too.
China government incentive 60000EURO/pc subsidy for E-bus and 6000EURO/pc for E-car is such a big cake,everyone crazy for it.
YEs John, we know very well all Chinese seller....ALL the same!!!:-)
Not,we are different,most of lithium battery companies like TS,GBS are busy on collecting money,but we just focus on products and quality.
We will see when you sent to us some batteries to test!
Agree?
You welcome to start with samples
Send me a sample.. I already have tested GBS, YESA, TS, HEADWAY and many others...
I can do a side by side comparison with each and give C-rate graphs, performance curves, impedance measures, etc, etc..
You welcome to start with sample order,pls E-mail to me more detail so that I may send PI for your payment.
You are misleading people.
Could you please tell me what is inner resistance mainly used for?
If 0.3MΩ it means, when a 40AH battery discharge with 10C, it would only have voltage drop about 40*10*0.3*0.001= 0.12V
So, when your 40AH battery discharge with 400A countinous currnt, open-circuit voltage is 3.3V, when battery got to load voltage would dorp from 3.3V to would dorp from 3.3V to 3.18V,
Could you please give us such a discharge curve?
And, since you using a inner-resistance measure machine, you should know that such machine is not accurate very well, and if you take AC calculate or DC calcultae method, you would got total differnct results.
Maybe your battery is well but you can not use this way to push it, we do not suggest misleading people.
Anyway, best LFP lithium battery in China is definitely not your company. As I know BYD battery is really good, and price, 1 pcs of 18650 LFP cell would cost 6 USD, a pcs of 18650 may only have less than 2 AH.

I am not engineer,I don't know how to calculate the voltage and impedance, and I don't know if our machine is accurate or not, but on my photos shttp://visforvoltage.org/forum/10381-cell-impedance-thundersky-and-chl-lithium-battery#comment-57404 ,It is very clear that TS,Sky energy are test at the same machine and same room and almost same temperature ,the result is just want to compare between different cells.
Ok,pls get one piece battery from BYD and show us its impedance here,let's check.... My boss ever been to BYD plant 3 times,nothing special....only mystery.
By the way,I think Hipower is pioneer in field of LFP battery,could you show everyone here one cell of yr 40AH battery impedance ? Let's show fact instead of wrangles.
If your big company don't even have a "no accurate" machine,I would like to do the job for you. Pls send to my company and I will test and post the result here.
I never claim that CHL battery could be 10C discharged,so that we don't have curve of 400A discharged.
By the way,CHL battery is really very very low voltage dropped when full throttle...... around max 150A output from our controller of testing E-scooter.
If you don't believe,you may come to have a test here. We don't have such big current curve.
What would it cost me to test 8-12 cell samples..
If only one, how much?
Maybe 4 at once.
I have 36v 50a motor/controller and many TS and Headways..
I could run 4 of yours and 4 TS and 4 headways in series and show graphs of all related information pertaining to discharge curves, voltage drops,charge curves, impedance measurements, etc,etc.
Shipping to FL USA
Ok,pls give us your full name and address include post code so that we may check the freight and make PI for you.
One container will be shipped to Santiago,USA 10 days later,if you can pay within this week,we may ship sample there and you just collect from Santiago,is it Ok ?
I think it is no way to ship lithium by air or by post.
Wrong...you can ship by air, but not all LPH can....
Where is Santiago? What state? I'm in Florida...
Santiago is south california.
What should we do shipped by air ? we have got MSDS certificate,but they said it is not enough !
Oh.. You mean, San Diego!
San Diego is 3,000km from Florida, no way, I could pick it up.
Lol
My nearest port is Miami, FL. That is only 70km away. Lol
Ok,I quote you 2 prices,by sea and by air if possible,and you make decision. Pls send mail to chlbattery [at] gmail.com including your company name and address for us to type PI
Finally our website come out www.china-huali.com
Now our impedance of 50AH even reduce to be 0.18mΩ,better and better ....
Hi,
and what about 60ah cells?
Do you have also size?
Yes,I have lucky to Visit HIPOWER last week,here is their impendance of 50AH and 40AH LFP battery,it is better than TS,but worse than CHL.
The biggest problem of Hipower batteries are that there are too much difference between cells,I think it is because of hand-folding films instead of automatically machine.
It is very strange that Hipower's 50AH is 0.598mΩ more impedance than 40AH 0.455mΩ ,normally bigger capacity should be less impedance.
I can verify this!!
I got my 8000w scooter in Australia a month ago and at full throttle I pull up to 120Amps and the voltage only drops from 79.8v to maybe 76v. Not much at all. When I had Thundersky cells under 95A they would drops from 79.8v to 64v and trip the low voltage switch.
1370km with CHL cells so far and not a single problem.

Thank you for your infomation. I learn more.
This morning I rode into work on my 8000w scooter in VERY COLD weather and pulling 120 amps from my 50Ah CHL cells, my voltage dropped from 79v to around 75.8v...that's it!! I have just passed 2500km with these batteries and they are still gaining capacity! My scooter still does not have a BMS and everything is going great.
Hey CHL, how are you going with that 72v 50Ah BMS?? When will you be sending some to Erider in Australia?
Thanks.
