What's LiFePO4 battery?
The lithium iron phosphate (LiFePO4) battery, also called LFP battery, is a type of rechargeable battery, specifically a lithium-ion battery, which uses LiFePO4 as a cathode material. LiFePO4 batteries have somewhat lower energy density than the more common lithium cobalt oxide (LiCoO2) design found in consumer electronics, but offer longer lifetimes, better power density (the rate that energy can be drawn from them) and are inherently safer. LiFePO4 is finding a number of roles in vehicle use and backup power.
What's the difference between them ?
Winston Battery Limited was founded in by Mr Chuang, he is a mystery gentleman. no one know where is he from and his experience before . and he set up Winston battery Limited on in Shenzhen and the company is one of pioneer of big capacity prismatic LiFePO4 Battery. nearly 90% of winston battery was sold to overseas market especially in Europe and USA. the production factory of Winston Battery located in shenzhen since ,they invested over 200 million USD to build their new factory in Zhangzhou, fujian province since and their new factory is much bigger and with better production facilities.the new production line start produce cells in volume since and it helps winston provide cells in time after clients place order. Winston Battery changed its name to smart lion battery limited and changed its logo since April of .
Winston Battery Limited is the biggest producer in China until CALB was founded in by China Aviation Industrial Limited,which is a leading state owned compay.with big investment on production line and research of new lithium technology,CALB has a bigger scale than winston battery limited from . production facility of CALB located in Luoyang includes 5 factories and over 3,000 employees. over 200 researcher and expert working in R&D department help CALB improve its technology year by year. the quality of CALB improved a lot. the main market of CALB are electric bus companies,CALB not only provide battery cells but also provide full power solution for electric vehicles. they integrate battery cells into battery packs for electric vehicles with BMS inside. they created a big market.
Sinopoly Battery Limited is a form join venture between thundersky Battery (form name of Winston Battery) and Shouchang capital.Shouchang Capital is a public company in Hongkong stock exchange market. with 1 year cooperate, Sinopoly and Thundersky break up conflict and fight in court. Thundersky changed its name to Winston Battery and Sinopoly purchased a lithium battery factory in liaoyang,north east of China, and they start produce lifepo4 battery themselves.
with 5 years high speed development, Sinopoly has 2 lifepo4 battery factory now. their new lifepo4 battery factory located in Tianjin with great production lines.
Winston battery has much more model battery cells, with capacity of 40Ah, 60Ah, 90Ah, 100Ah, 160Ah, 200Ah, 300Ah, 400Ah, 700Ah and Ah.
CALB battery has 5 battery cells with capacity of CAM72, 100Ah, 180Ah and 200AH (CA200 and SE200).
Sinopoly Battery has 4 different battery cells and the capacity of the lifepo4 battery cells are 40Ah, 60Ah, 100Ah and 200Ah.

Our batteries are true "A" grade and shipped to you directly from the Sinopoly factory.
They are not "B" grade batteries re-marketed as "A" through Alibaba or other Chinese platforms for sale to the United States and Europe.

Why is it impossible to buy grade-A LiFePO4 cells?
I'd like to introduce myself, explain a bit about the Lithium market, and why you should buy your batteries from Sinopoly USA.
My name is Alex Dorsey. In I set off on a journey to sail the world and I'm still at it. I single-handed across the Pacific in on a 28' sailboat. Now, nearly twenty years later, I'm still sailing the world but with my wife Carla (Argentina) and our two rescue dogs Nacho and Chewie (www.projectbluesphere.com).
In mid I became interested in LiFePo4 batteries. As we live full-time off of our solar energy system, the upgrade to LiFePO4 was a practical and logical step. I knew finding a good source of LiFePO4 cells was key. After six months of research, I decided on an Alibaba supplier that was "verified" and purchased my sixteen A-quality (paid more for A) 200ah cells under the "Trade Assurance" program. I did everything right, or at least I thought I did?
Well, after receiving my cells nearly two months later, I tested them thoroughly and was more than unhappy with the results. Testing large capacity cells is a long and arduous process that most people do not do. Two of my cells were unusable and the supplier was compelled to replace them, which he did. I was now the proud owner of 18 B quality cells which the "trade assurance" program would not right three and a half months after placing my order. They worked well enough but I had to adjust my charging profile and I know I won't get the lifespan from them that was advertised by the manufacturer.
Now, that being said, there is absolute value to grade-B cells and/or purchasing used cells. My grade-B LiFePO4 battery bank far outperforms any other battery technology I've had in my 31 years of sailing, and I have had them all. Grade B just isn't what I wanted or paid for. I expected my hard-earned investment to last 12+ years, which I know it will not.
I was determined to get answers. Why is is so hard for Americans and Europeans to buy A-quality LiFePO4 cells? The answer is long and complicated but you have to understand how the industry works, what the laws are in China, shipping regulations for lithium, and understand the United States trade war with China.
Firstly, every A-quality cell that is produced is already sold. The world is desperately trying to fight global warming and move to clean energy solutions. That means lithium powered electric vehicles, and utility scale lithium storage solutions. The truth is the industry is working at capacity and factories are not focused on B2C business (you and me).
Secondly, anywhere between 3-12% of a manufacturing run of cells are considered B as some factories have very high quality requirements. It is illegal for a Chinese manufacturer to export B-quality cells abroad, they must be sold very cheaply to the Chinese people, who in turn sell them on Alibaba and other platforms to the world market. Other people buy them in bulk and they end up on Amazon and eBay, and others build them into off-brand battery packs. This is why everyone keeps getting sub-par and bloated cells, and cells that just don't last that long.
As far as shipping costs, you must also realize a few things. Due to Covid, the cost of a shipping container has soared from about $1,500 to nearly $8,000 in the last year.
You must also understand that there is a 25% trade war tariff on importing these batteries into the United States aside from the normal 2.5% import tax. So if you buy $10,000 in cells you will have to pay $2,750 in import duty to the United States not including shipping, insurance, special lithium handling, or storage.
If you do a little research, and please do, you will be surprised as to all the costs and safety regulations, and how difficult it is to buy true grade-A LiFePO4 battery cells.
Well, I was determined to find a way. I spent eight months communicating with various Chinese factories and making contacts. The Lithium market is like the old west gold rush. Everyone is fighting to position themselves in the stream in the most profitable way. Despite all the competition, I ended up making a few good friends along the way and forged a solid relationship with Sinopoly. Sinopoly is one of the largest and oldest producers of LiFePO4 cells in the industry. Really a great group of people that are not only dedicated to producing the highest quality batteries, but have deep environmental roots as well.
This is how sinopolyusa.com, and sinopolyeu.com were born.
After eight months of negotiating, I was able to slice a small piece of a very large pie for the DIY LiFePO4 community.
What I can promise you is access to true A-quality LiFePO4 battery cells direct from the Sinopoly factory at a fair price. During the first few months of my business, I will be shipping directly from the Sinopoly factory in China, but I'll be warehousing my stock in Canada & Italy for distribution to the Americas & Europe.
My intention is to sell to the B2C community however my main focus is B2B operations and helping others set up their own business around the world as I am approved to offer wholesale pricing from Sinopoly.
If you have any questions please feel free to reach out to us.
Peace.
Sail far and live slowly.
