Im David from Sinopoly Battery Limited (Sinopoly).

Sinopoly costed HK$2.75 billion to purchase Thunder Sky Battery Limited in 25th May, 2010.

Regarding the Announcements, please visit the vents "Dec 2009, The Company entered into a letter of intent to purchase a lithium battery project for HK$2.75 billion" and "May 2010, The Acquisition in relation to the lithium battery project is completed" of following link,

Thunder Sky changed its name as Winston Battery Limited and still sell LiFePO4 battery. As this action has deeply infringed on our company's related benefit, Sinopoly prosecuted Winston and recommend all the customers to stop purchasing Winston battery.

World War between TS and Winston ..... everyone are focus on funding instead of technology.

Mr Winston get rich from selling his technology instead of products. But his technology have no improvement during passed 10 years. Very bad reputation in china.

Re: Sinopoly-LiFePO4 Battery Supplier

I purchased (8) 100 a-hr cells from Balqon back on 8-24-2012 and finally received then today 12-3-2012. After sharing these pictures on the Cruiser's Forum (sailboat cruising) I was told they were at least 3 years old Thunder Sky and not current production Winston cells with lower C rates for charging and discharging. Was also informed the cycle life on these cells is 2000 @ 80% DOD, whereas the new cells are 5000 cycles. Would love someone to shed some light on this for me.

I think Balqon took advantage of me. This was my small cell purchase, I'll do better retailer research before the 52 kw-hr purchase.

Re: Sinopoly-LiFePO4 Battery Supplier

I don't know the histories on these companies. I wound up doing business with Balqon only because of reading some press release stating they were a Winston distributor. This purchase was the small one, so I'm up for learning more on who is moving these cells at a good price. My next purchase will be (16) 1,000 a-hr cells and Balqon has them at $13,800.
