Thunder Sky is a major player in the development and production of LiYePO4 Rare Earth Lithium Ion batteries. Thunder Sky started experimenting with electric vehicles around the turn of the last century by converting existing petrol powered cars to electric power. This included, as you shall discover from this article, everything from the humble Geo Metro to über collectible Hongqis. Join me as I take you on a journey to discover one of the most ambitious, ingenious and downright insane (in a good way) companies we will ever discuss here on the pages of China Car History. A journey so long it has to be split across two articles. The first shall cover all their vehicles prior to 2007 and the second everything after. Please note that right up until the day of publishing we were uncovering more and more vehicles produced by Thunder Sky and likely may find more in the future so these articles will more than likely be updated.
