21700 13S4P 20Ah 48V electric bicycle lithium battery pack

The 21700 13S4P 20Ah is a electric bicycle lithium battery pack intended for electric bicycles and light electric mobility. System selection should confirm the equipment voltage, continuous and peak load, installation space, and required certifications.

The confirmed core ratings are 48V, 20Ah, 960Wh. Electrical limits include maximum charge voltage 54.6V; discharge cut-off voltage 32.5V; maximum charge current 10A; continuous discharge current 20A; peak discharge current 40A. 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 54.6V; discharge cut-off voltage 32.5V; maximum charge current 10A; continuous discharge current 20A; peak discharge current 40A. 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: 77×89×300mm; weight: 4kg. 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.
