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 within a compact 79 × 77 × 197 mm form factor while weighing only 2.31 kg for easy handling and installation in space-limited setups. Built around high grade lithium cells paired with a precisely matched 7S configuration, the battery charges up to 29.6V at a 1C standard rate, supports continuous discharge up to 3C under load with a 19.2V cut off threshold, and maintains a smooth, flat voltage curve that helps your scooter, e bike or standalone power system sustain steady performance for longer periods without premature voltage sag.

The robust deep cycle design supports thousands of charge discharge cycles under typical operating conditions, making it a dependable power solution for electric scooters, motorcycles, e bikes, lawn mowers, emergency backup power units and compact small solar storage systems. Shipped directly from our manufacturing facility, every finished battery pack undergoes comprehensive full inspection and rigorous charging performance testing prior to packaging. This direct factory model brings you factory direct pricing, consistent batch-to-batch quality, and flexible lead times that accommodate both small sample requests and large volume bulk orders.
