18650 3S1P 3500mAh 10.8V lithium-ion battery pack

The 18650 3S1P 3500mAh is a lithium-ion battery pack intended for OEM electronics and custom battery assemblies. System selection should confirm the equipment voltage, continuous and peak load, installation space, and required certifications.

The confirmed core ratings are 10.8V, 3500mAh, 37.8Wh. Electrical limits include maximum charge voltage 12.6V; discharge cut-off voltage 8.1V; maximum charge current 3.5A; continuous discharge current 4A; peak discharge current 8A. 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 8.1V; maximum charge current 3.5A; continuous discharge current 4A; peak discharge current 8A. 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: -20~+60°C; dimensions: 20×56×70mm; weight: 152g. 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.
