Nominal voltage: 7.4V; Rated capacity: 4000mAh; Charging voltage: 5V; Charging current: 2A;

The 18650 lithium-ion battery pack is formed by spot-welding of 18650 cylindrical cells in series or parallel. The resulting battery has a high energy density and a low cost cycle life compared to other power supply options. The cylindrical cell format also shows high reliability compared to other formatting options.

The battery pack specifications make it suitable for power tools, laptops, consumer electronics and many other applications.

The battery uses a high-quality cylindrical battery with a medium weight energy density class and a medium maximum continuous current discharge class compared to other batteries.

Assembly and testing takes place at our factory in Zhongshan, China. PCM/BMS, connectors, labels, package shapes and other requirements can be adapted.

All Venier packages usually start with a free replacement warranty of 6 to 12 months or more, covering authenticity, performance, age and defects. Due to the variability of battery pack specifications, applications, and custom parts, warranties may be determined on a per-product basis.
