25.9V 28Ah 7S Lithium Ion Battery Pack 725Wh Large Capacity Rechargeable Deep

Product Specification

25.9V 28000mAh high‑capacity drone battery

1 Product Introduction  

  Engineered specifically for demanding mobility setups and reliable off grid power applications, this 25.9V 28Ah 7S lithium ion battery pack delivers a steady, usable energy capacity of 725Wh within a tightly compact 79 × 77 × 197 mm form factor, while weighing just 2.31 kg for easier handling and installation. Constructed using high grade lithium cells paired with a precisely matched 7S internal configuration, the battery charges to a maximum voltage of 29.6V at a standard 1C charging rate. It supports continuous discharge output up to 3C under active load conditions with a 19.2V low voltage cut off threshold, and it features a consistently flat voltage curve. This stable discharge profile helps your scooter, e bike or standalone power system maintain strong performance for extended runtimes, preventing unwanted early voltage sag mid-use.

Featuring a robust deep cycle design, this battery can withstand thousands of complete charge discharge cycles under typical operating conditions.    That long cycle life makes it a dependable power solution for electric scooters, electric motorcycles, e bikes, lawn mowers, emergency backup power units and compact small solar storage systems. All battery packs ship directly from our own manufacturing facility. Before final packaging, every individual pack goes through a comprehensive full inspection procedure and formal charging performance test. This direct factory model brings you factory direct pricing, stable and consistent batch-to-batch quality control, alongside flexible lead times to accommodate both small sample requests and large-volume bulk orders.
