After two years’ efforts, R&D dept. has new achievement on the 4.4V and 4.35V high voltage system for lithium polymer battery.
High energy density means that the same size battery would provide higher capacity and longer life. 4.4V system battery has energy density about 13.8% higher than the 4.2V system. The 4.35V system battery has energy density about 10.7% than the 4.2V system. It bring customers better experience in power life.
