25.9V 50Ah 7S Lithium Ion Battery Pack Rechargeable Industrial Battery With BMS

Product Specification

25.9V 50000mAh high‑capacity drone battery

1 Product Introduction     

  This 25.9V 50Ah 7S lithium battery pack is specially built for industrial users who demand consistent power reliability, long service life and safe operation in heavy-duty working environments. Featuring a high capacity 50Ah design, the pack delivers steady, sustained energy output for industrial equipment, machinery, power backup units, mobile power systems and other high-demand applications that require stable power supply over extended working periods. It runs at a nominal voltage of 25.9V with a maximum charge voltage of 29.8V and a cut off voltage of 17.5V, while supporting standard 1C charge and discharge operation to guarantee stable daily use under regular operating loads.

  The battery pack comes fitted with an integrated battery management system that helps protect the battery cells against overcharging, over discharging, overcurrent and short circuits during operation. This built-in multi-layer protection mechanism contributes to safer day-to-day operation, longer cycle life and more consistent performance across a wide range of different load conditions. Its compact structure and optimized weight profile also make it much easier to install, integrate into existing equipment frameworks and transport compared to conventional bulky and heavy power solutions.

  Every single pack is manufactured in-house through a fully controlled production process with strict inspection carried out at every production stage, including precise cell matching, comprehensive performance testing, accurate voltage verification and complete safety validation before final shipment. This factory direct approach allows us to maintain tight end-to-end quality control, cut down unnecessary middle costs and provide more responsive technical and after-sales support for bulk orders, custom modification requirements and various project-based applications.

Whether you need a dependable power source for industrial machinery, emergency backup power systems, mobile energy equipment or specialty custom battery projects, this 25.9V 50Ah lithium pack combines large high capacity, stable continuous output and factory-backed reliable quality into one robust and trustworthy power solution.
