Factory Direct Lithium Battery Pack for Reliable Energy Storage and Custom Applications

For OEM buyers working with a tight battery bay, HSS Energy builds the China 7.4V 2600mAh Battery Pack as a slim 2S1P power pack using two 18650 NCM cells. Its main advantage is not a long feature list; it is a straightforward shape that is easy to evaluate inside compact equipment. We match the connector, lead direction and protection settings to the approved sample. In short: fit the battery to the device, not the device to the battery.

Space is tight. HSS Energy offers the China 7.4V 2000mAh Battery Pack to OEM buyers who still need a practical 6A output from a small power module. Inside are two NCM 18650 cells in a confirmed 2S1P arrangement. Outside, the pack stays compact at approximately 38 x 20 x 68mm and 0.12kg. Rated capacity is 2000mAh. The connector is not treated as an afterthought: its type, polarity, lead length and exit direction are settled against the equipment drawing before a sample is built.

The 3.7V 2600mAh Battery Pack from HSS Energy supplier gives OEM buyers more runtime in one 18650 cell. It is a practical choice when the device already uses 3.7V power, the battery space cannot grow, and the 2000mAh class falls short of the target operating time. Connector, lead, polarity, label and packaging can be settled around the customer's drawing before quotation, so the sample arrives closer to the version needed for production.

Need a smaller power source? The 3.7V 2000mAh Battery Pack from HSS Energy manufacturer is built for OEM sourcing around a confirmed 1S1P 18650 NCM layout. It is a sensible starting point when the equipment needs single-cell voltage, a narrow cylindrical shape and a connector fixed to the drawing. Send us the load, battery-space and interface details; we can then review the pack, sample route and quotation around the device instead of asking you to choose from a generic list.
