QPF20DA 20Ah Lithium-Ion Cell: High-Rate Performance, Ready Stock, Competitive Pricing

If you are sourcing a 20Ah lithium-ion cell for high-power applications, the QPF20DA is a practical option to evaluate. We currently carry large stock and can offer favorable pricing for B2B buyers.

Product Introduction

The QPF20DA is a 3.2V nominal, 20Ah lithium-ion cell. It is built for applications that need both capacity and high current.

It supports up to 30C continuous discharge and 32C pulse discharge for 30 seconds at 50% SoC. Continuous charge is up to 8C, with 1C standard charge.

Internal resistance is low: AC impedance ≤0.5mΩ and DC resistance ≤1.2mΩ at 50% SoC. This helps reduce heat during high-rate operation.

Standard cycle life is ≥2000 cycles. At 8C/8C cycling, cycle life is ≥1200 cycles. For many high-power packs, this supports a lower total cost of ownership.

Key Buyer Benefits

High-rate performance for power tools, AGVs, hybrid systems, and other high-current packs.
Stable discharge at high and low temperatures: ≥95% initial capacity at 55°C, ≥80% at -20°C.
Good charge retention and recovery for storage and standby applications.
Low resistance helps system designers manage heat and efficiency.

Design and Integration Notes

A BMS is mandatory. The cell must be monitored and protected throughout its service life.

Key BMS thresholds include:

Charge: stop at 3.65V, force stop at 3.70V, lock at 3.75V.
Discharge: stop at 2.50V, force stop at 2.30V, lock at 2.0V.
Over-temperature protection: -45°C to 60°C.

Charging operating temperature is -20°C to +45°C. Discharging operating temperature is -45°C to +55°C. Low-temperature charging outside the allowed range should be avoided.

Thermal management is important. The enclosure must handle heat, water, dust, and pressure relief. The cell uses an explosion-proof valve for venting.

For mechanical design, preload force is required. The recommended range for fresh cells is 500N to 5000N. Cells expand with SoC and age, so the pack must reserve space for swelling.

The weldable pole area is 34×16mm. Maximum weld penetration is 3mm. Torque should be ≤6N·m. The top cover can withstand pressure up to 1200N.
