25.9V 28Ah 7S Lithium Battery Pack 725Wh High Capacity Rechargeable Li Ion Battery Grade A Cells For Electric Scooter Motorcycle E Bike Lawn Mower Backup Power Supply Deep Cycle Long Life

25.9V 28000mAh high‑capacity drone battery

1 Product Introduction  

  Engineered for demanding mobility and off grid power applications, this 25.9V 28Ah 7S lithium ion battery pack delivers a stable 725Wh of usable energy in a compact 79 × 77 × 197 mm form factor weighing only 2.31 kg. Built around high grade cells and a matched 7S configuration, it charges up to 29.6V at 1C standard rate, discharges continuously up to 3C under load with a 19.2V cut off, and maintains a flat voltage curve that keeps your scooter, e bike or power system performing longer without early sag.

 The deep cycle design supports thousands of charge discharge cycles under normal use, making it a reliable choice for electric scooters, motorcycles, e bikes, lawn mowers, backup power and small solar storage systems. Shipped directly from our manufacturing facility, every pack undergoes full inspection and charging testing before packaging, giving you factory direct pricing, consistent batch quality and flexible lead times for both sample and bulk orders.
