25.9V 22Ah 7S Lithium Battery Pack 5C Max Continuous Discharge 29.4V Charge

Product Specification

25.9V 22000mAh high‑capacity drone battery

1 Product Introduction

  Engineered as a complete, ready-to-install power solution, this 25.9V 22Ah lithium ion battery pack delivers up to 569Wh of reliable usable energy—optimized for consistent performance across demanding applications—in a remarkably compact, lightweight housing that measures just 75 × 76 × 195 mm and weighs only 2.34 kg. Built around a precision-engineered 7S cell configuration, it is specifically designed for equipment that demands unwavering stable voltage, robust high discharge capability, and an extended long service life, featuring a flat discharge curve that reliably holds a steady 25.9V nominal output, charges efficiently up to 29.4V (the optimal full-charge threshold for lithium ion cells), and discharges safely down to 19.2V (protecting cells from over-discharge damage). It supports an impressive up to 5C continuous discharge rate, which translates to roughly 110A of sustained current, ensuring high-power loads such as drive motors, heavy-duty power tools, and mobility equipment operate smoothly without voltage sag or performance drop-offs. Additionally, its ability to accept up to 2C (or approximately 44A) maximum continuous charge current significantly cuts recharge downtime, minimizing operational interruptions and keeping your project, equipment, or product up and running with minimal delays.

  At its ultra-portable 2.34 kg weight and space-saving 75 × 76 × 195 mm dimensions, this battery pack fits seamlessly into tight battery compartments and confined installation spaces, making it exceptionally well suited to a wide range of applications: electric scooters, e-bikes, mobility scooters, golf carts, RV and marine backup power systems, off-grid solar storage setups, industrial robots, and automated guided vehicles (AGVs).

Crucially, we are the original equipment manufacturer (OEM) rather than a middleman trading company: every battery pack undergoes meticulous assembly, rigorous performance testing, and controlled aging processes on our in-house production line before shipment. This direct manufacturing approach ensures you benefit from factory-direct pricing (eliminating unnecessary markup), consistent quality control standards (adhered to at every production stage), and full traceability—from the source of individual cells to the finished battery pack, with comprehensive documentation available upon request. We fully support OEM and ODM customization to align with your specific requirements, including tailored capacity adjustments, custom connector types, specialized wiring harness designs, and branded packaging or labeling. We ship directly to distributors, professional installers, and brand owners worldwide, catering to both small-scale needs—such as a single sample for product evaluation or testing—and large-volume orders for mass production lines. Our commitment to reliability extends beyond the product itself, with stable lead times (backed by streamlined production planning), strict incoming-to-outgoing quality control (inspecting raw materials, components, and finished packs), and responsive after-sales support to address any technical questions, troubleshooting needs, or service requests promptly.
