Cameron Sino 5200mAh 57.72Wh 11.1V Li-Poly Battery Lucky Duck 21-11120-8

Compatible replacement for Lucky Duck Agitator HDi

This 5200mAh lithium-polymer battery delivers 57.72Wh at 11.1V and matches the original part number 21-11120-8. It is built to the same dimensions of 70.50 x 55.50 x 37.70mm so it fits the Drake, Hen & Goose and Kennel Fan models without modification. A fully decoded chip ensures the same communication with the device as the factory pack. The cell carries ISO9001 certification and includes overcharge, over-discharge, over-voltage and short-circuit protection.

Upgrade from a depleted or ageing original pack

When the stock battery no longer holds a full day’s charge or shows swelling, this unit restores the agitator’s runtime to factory levels. The jump is worth it if the original cell has passed its useful cycle life or if the protection circuit has begun to cut power early. Installation videos are widely available and the connector mates directly, so the swap takes only minutes with basic tools. No firmware update or adapter is required.

Check the model and part number before ordering

Verify that your agitator is the Lucky Duck Agitator HDi - Drake, Hen & Goose or Kennel Fan and that the original battery bears part number 21-11120-8. Confirm the connector layout matches the replacement photos to avoid a misaligned plug. Plan for two or three full charge-discharge cycles to reach peak capacity. Use only a quality charger; low-grade third-party adapters can reduce service life.
