            EV Li-ion battery
            Lithium-ion batteries used in pure EV and hybrid EV are required to have good performance in high power output in safety, consistency, reliability, cycle and charge retention. Our company adopts NCM and LFP materials from domestic well-known enterprises, with reasonable design layout and good battery consistency. The discharge rate is generally below 4C.
            Application area
            This series of batteries are specially designed and developed by Tianneng for new energy vehicles, including electric cars, buses, micro electric vehicles, logistics vehicles, sanitation vehicles and special vehicles. The products have a number of national patent technologies, and are safe, environmental friendly, portable and long-life.
