OID 98122319 57Ah 3.65V 3C Ultra-High Capacity Lithium Polymer Battery
\nThe OID 98122319-57000mAh-3.65V-3C-0112 is a premium single-cell lithium-ion polymer battery engineered by Shenzhen Jianheng Technology Co Ltd for applications that demand extreme capacity, long endurance and high discharge rate capability. With a typical capacity of 57.0Ah and a minimum capacity of 55.0Ah, this cell delivers reliable power for electric vehicles, energy storage systems and high-performance UAV platforms.
\nBuilt with an aluminum plastic film shell and advanced electrode technology, the OID 98122319 achieves an ultra-low AC impedance of no more than 1.0mΩ at 1kHz (58% SOC), enabling high continuous discharge currents up to 3.0C and pulse currents up to 8.0C for 10 seconds. This makes it an ideal choice for drone battery packs, eVTOL systems and other high-power applications requiring stable performance and long cycle life.
\n\nKey Selling Points
\n- \n
- Ultra-High Capacity for Extended Endurance: Typical 57.0Ah and minimum 55.0Ah capacity at 0.5C within 4.2V to 2.75V. Provides exceptional energy density for long-flight UAV missions and high-capacity energy storage systems. \n
