TES series is special designed for energy cyclic use. It can deliver very  long cycle life even under partial state of charge (PSOC). The charge efficiency is also higher than normal lead acid battery. Combined with high vibration resistance & explosion-proof design. The inner unique  connection structure can provide the highest reliability for today's energy  storage solutions. It is recommended to be used in Wind Power / PV  Energy Storage System, Micro - Grid Energy Storage System sand  Smart Grid Energy Storage System.
