301730 120mAh 3.7V smart home lithium battery pack

The 301730 120mAh is a smart home lithium battery pack intended for smart home devices and connected electronics. System selection should confirm the equipment voltage, continuous and peak load, installation space, and required certifications.

The confirmed core ratings are 3.7V, 120mAh, 0.444Wh. Electrical limits include maximum charge voltage 4.2V; discharge cut-off voltage 3.0V; maximum charge current 1C; continuous discharge current 1C; peak discharge current 1A. 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 4.2V; discharge cut-off voltage 3.0V; maximum charge current 1C; continuous discharge current 1C; peak discharge current 1A. Verify connector polarity, cable sizing, fuse selection, and BMS communication before commissioning.

The confirmed physical and service information is cycle life: ≥300; charge temperature: 0~45°C; discharge temperature: -20~+60°C; dimensions: 3×17×32mm; weight: 3g. 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.
