Product Specification

44.4V 28000mAh high‑capacity drone battery

1 Product Introduction        

  This high performance 12S 44.4V 28Ah lithium battery pack is engineered to deliver stable and reliable power output for industrial unmanned aerial vehicles and other heavy load mobile equipment. Rated at 28Ah nominal capacity with a 3C maximum continuous discharge capability, this battery maintains consistent power delivery under high working loads while keeping excellent voltage stability. The pack features a compact dimension of 13577198mm and a lightweight 3.91kg body, balancing energy density and portability for field deployment.

  We are the original manufacturer offering factory direct shipment to global buyers. Every battery pack undergoes strict quality testing during production to ensure safety and long cycle performance. Built in protection mechanism safeguards the battery against overcharge over discharge over current and short circuit, greatly extending service life. The standard charge current is 1C with a maximum charge voltage of 51V and cut off discharge voltage at 33V, fully optimized for daily cyclic operation. Customization options are available for connector and cable configuration to match your equipment requirements.
