Grepow NMC 811 battery uses a stacked-sheet pouch cell process, the NMC (Ni-Mn-Co) cathode composition with 80% nickel, 10% manganese, and 10% cobalt. This recipe technology is to significantly break the energy density of existing lipo batteries, which the highest energy density is 275Wh per kg. The capacity Retention can stay more than 90% after 600 cycles and the dynamic voltage imbalance is less than 100 mV. This technology is more reliable and light, it has a longer range for professional field drones such as mapping, E-VTOL and consumer electronics. NMC 811 batteries can also be customized to perfectly fit the shape or capacity of the appliance you need. As a battery manufacturer, we take OEM and ODM services as well.
