What is the real experience with LiFePO4 batteries?

Answer: The Winston Battery (formerly Thunder Sky) has been producing the LiFePO4 batteries since 2004. The first large volume customers were from the USA. These American customers have been using the LFP batteries from some 5 ~ 6 years with full satisfaction. (Even though there were some problems with the quality of the cells from some of the early production batches.)  It is important to note that over the years the technology has been developing. The new LiFeYPO4 technology is much more stable and production quality also continues to grow.

FAQ: I purchased a new LP 12V battery. Why is the battery different from the model I purchased several years ago?

Answer: The original Thunder Sky 12V LP batteries used to have electrochemical balancing (with a floating electrolyte). There were produced from 2007 till spring of 2009. Later versions contained individual cells with mechanical separation. The production of the original LP batteries was stopped in 2009. The news models (40Ah, 60Ah, 90Ah) are produced using individual single cells that are selected in the factory to match the performance and capacity.
