| High Light | 18650 2S1P Cylindrical Battery Pack ，7.4V 3500mAh 25.4Wh Li-ion Pack ，Rechargeable OEM Lithium Battery Pack | ||
This rechargeable 18650 2S1P lithium-ion battery pack is assembled from two Grade-A 18650 cylindrical cells connected in series, delivering a standard nominal voltage of 7.4V, a rated capacity of 3500mAh and a total energy of 25.4Wh. Built for stable, long-lasting power, it is an ideal power core for portable electronics, backup power systems, portable speakers, medical devices and other 7.4V battery-powered equipment.
Every cell is capacity-sorted and voltage-matched before assembly, then finished with a durable PVC heat-shrink casing and a built-in BMS protection board. This guarantees consistent batch performance, low internal resistance and reliable long-cycle operation — exactly what B2B buyers need for volume production and global export. Full OEM & ODM customization is supported, including wire length, connector type, housing, capacity matching and private-label printing.
