12S 44.4V 28Ah Rechargeable Lithium Battery Pack High Capacity 3C Continuous

Product Specification

44.4V 28000mAh high‑capacity drone battery

1 Product Introduction        

  This high capacity 12S 44.4V 28Ah lithium battery pack is built to deliver reliable and stable power for demanding industrial applications. It supports a maximum continuous discharge rate of 3C and maintains consistent energy output under heavy load conditions, making it an ideal power solution for industrial UAVs, mobile robots, portable power systems, and other heavy duty equipment. The 28Ah rated capacity provides extended runtime, while the compact lightweight design helps improve system efficiency and flexibility.
  With a maximum charge voltage of 51V, a standard charge current of 1C, and a discharge cut off voltage of 33V, the battery pack is optimized for cyclic industrial use. Integrated safety features protect against overcharge over discharge over current and short circuit, helping to ensure safer operation and longer service life. The pack measures 135 77 198mm and weighs 3.91kg, offering a practical combination of power capacity size and weight for equipment integration.
  We are the original manufacturer providing factory direct shipment with strict quality control. Every battery pack is tested during production to verify performance consistency and safety. Custom connector and cable configurations are available to support different installation requirements.
