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

For OEM buyers, HSS Energy's 12V 10Ah LiFePO4 Battery Pack provides a compact 128Wh-class starting point for smaller 12V systems where installation space and current demand need to stay controlled. The supplied configuration is rated at 12.8V and 10Ah, uses 26700 5000mAh LiFePO4 cells in 4S2P, and lists 20A continuous discharge. It is a practical option for projects that need a defined charger profile, plastic enclosure and optional communication before the final terminal and interface details are frozen.

For OEM projects that need longer operating time from an 11.1V system, HSS Energy supplies the China 11.1V 5000mAh Battery Pack. Using NCM 21700 cells in a 3S1P configuration, it delivers 5Ah capacity, approximately 55.5Wh of energy and up to 15A continuous discharge. The pack remains compact enough for many devices, while connector and protection details can be matched before quotation

HSS Energy factory supplies the 11.1V 2600mAh Battery Pack for OEM buyers and equipment developers sourcing a compact rechargeable power module. The confirmed design uses three 18650 Li-ion cells in a 3S1P arrangement, providing 11.1V nominal voltage, 2600mAh capacity and about 28.86Wh nominal energy. Connector type, lead length, polarity, protection settings, wrapping, label and pack dimensions can be reviewed against the device before sampling. Send the load profile and mechanical limits for a project quotation.

HSS Energy supplies the 11.1V 2000mAh Battery Pack for OEM buyers and equipment developers looking for a compact rechargeable power module. The NCM 18650 design uses a 3S1P arrangement, delivers 2000mAh rated capacity and supports up to 6A continuous discharge. Measuring approximately 58 x 20 x 68mm and weighing about 0.15kg, the heat-shrink-wrapped pack fits space-conscious equipment. HSS Energy can review the connector, lead, polarity and label against the device before sampling. Send the load profile and charger details for a project quotation.

For OEM teams that need more runtime from an existing 11.1V system, HSS Energy offers the 11.1V 10Ah Battery Pack with 111Wh nominal energy and up to 30A continuous output. The confirmed NCM 21700 design uses a 3S2P arrangement. Depending on the project, A-grade EVE, DMEGC, BAK, LG, or Samsung cells can be selected, while the connector, BMS settings, cable layout, labeling, and finished dimensions are locked before sampling and quotation.

For OEM sourcing, HSS Energy factory builds the 7.4V 5000mAh Battery Pack in two genuinely different shapes. Buyers can choose a shorter, squarer 18650 2S2P pack or a slimmer, longer 21700 2S1P pack. Both use NCM cells and deliver the same rated voltage and capacity, so the better option usually comes down to the space inside the equipment. Before sampling, we match the layout, cable exit and connector to the customer's drawing rather than treating the two versions as interchangeable.
