I am David Zhao 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,
The Board is pleased to announce that with effect from 14 April 2011, the English name of the Company has been changed from “Thunder Sky Battery Limited” to “Sinopoly Battery Limited”.
Winston Battery served as a subcontractor for Sinopoly to manufacture lithium iron battery. So Winston can not sell battery without Sinopoly’s authorization. But Winston still sells 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. Now Thunder Sky is just one of Sinopoly’s brand names.
