*LONG WAY S series is specially designed for solar system & wind power system. According the condition of applications, Zhongshan Long Way Battery Manufacturing Co., Ltd., spent more than one year to develop and research S series. S Series performs excellent when it is recharged in high ambient temperature, discharge in low ambient temperature. S Series has good capacity retention under the poor recharging condition.
