VTC18650-3S2P 10.8V 8000mAh Lithium-ion Battery Pack Manufactures and Factory
The VTC18650-3S2P is a high-performance cylindrical Lithium-ion battery pack manufactured by VTCBATT. With a nominal voltage of 10.8V and a typical capacity of 8000mAh (86.4Wh), this 3S2P battery pack offers excellent energy density and a reliable power supply. The pack features compact dimensions of 23x38x200mm and a weight of approximately 310g, making it ideal for space-constrained applications. It is integrated with a premium Seiko S-8254AAN protection IC and six dp4407 MOSFETs, which provide advanced overcharge detection (4.250V per cell), overdischarge detection (2.50V per cell), overcurrent protection (18A), and short-circuit protection. It supports a standard charge current of 0.2C (1.6A) up to a max charge voltage of 12.6V, a rapid charge current of 4A, and a maximum continuous discharge current of 8A.
Designed for extreme operating environments, the pack provides robust discharge performance from -20°C to 60°C and charging from 0°C to 45°C, with built-in thermal protection that halts discharge if the surface temperature exceeds 70°C. As an established direct-factory manufacturer, VTCBATT provides comprehensive B2B wholesale supply, OEM/ODM customization, custom wire harness assembly, sample development, and stable high-volume production to support global equipment manufacturers and distributors.
