HX5642128 3S1P 4000mAh 11.1V low-temperature lithium battery pack

The HX5642128 3S1P 4000mAh is a low-temperature lithium battery pack intended for equipment operating in cold environments. System selection should confirm the equipment voltage, continuous and peak load, installation space, and required certifications.

The confirmed core ratings are 11.1V, 4000mAh, 44.4Wh. Electrical limits include maximum charge voltage 12.6V; discharge cut-off voltage 6V; maximum charge current 3A; continuous discharge current 3A; peak discharge current 4A. Use the final approved specification for charger and protection settings.

Use a charger and protection strategy matched to the battery chemistry, voltage, and current limits. For this model, the relevant limits are maximum charge voltage 12.6V; discharge cut-off voltage 6V; maximum charge current 3A; continuous discharge current 3A; peak discharge current 4A. Verify connector polarity, cable sizing, fuse selection, and BMS communication before commissioning.

The confirmed physical and service information is cycle life: ≥500; charge temperature: 0~45°C; discharge temperature: -40~+60°C; dimensions: 8.6×132×146mm; weight: 355g. Allow adequate ventilation, mechanical support, service clearance, and protection appropriate to the operating environment.

Yes. Hysincere can evaluate connector, wiring, enclosure, BMS, communication, label, and packaging requirements. Current integration information is connector, wiring, enclosure, and BMS options defined for the project. Final feasibility and specifications are confirmed through engineering review.
