Product Specification

25.9V 35000mAh high‑capacity drone battery

1 Product Introduction   

  This 25.9V 35Ah 7S lithium battery pack delivers reliable high-power output with up to 5C continuous discharge capability, making it well-suited to sustain heavy, fluctuating load power demands commonly seen in industrial equipment, robotics systems and portable outdoor power setups. Built with carefully selected high-quality lithium cells and equipped with an integrated BMS protection system, the battery maintains steady and predictable charge and discharge performance throughout operation. This built-in protection circuit effectively prevents hazardous conditions including overcharge, over-discharge, overcurrent and short circuit, helping to lengthen the overall service life of the pack and secure stable, risk-free operation for your connected devices.

  We are a direct manufacturer equipped with full, in-house production workflows and standardized quality inspection systems covering every production stage. Each finished battery unit goes through comprehensive, strict functional and safety testing before shipment, so you can receive products with stable, consistent performance batch after batch. Its compact outer dimensions and thoughtfully optimized weight profile reduce installation difficulty and save valuable internal space, allowing this battery to be easily mounted and seamlessly integrated into a wide range of host devices. We welcome large-volume bulk orders and also provide flexible customized solutions tailored to match the unique requirements of your different application scenarios.

  The battery features a nominal voltage of 25.9V, limited charge voltage of 29.8V and cut-off voltage of 17.5V, with standard 1C charge and discharge current for routine use. It boasts excellent long-cycle durability and consistently reliable power output even under extended, continuous working conditions. These electrical characteristics make it an ideal power source for stationary energy storage units, mobile power stations and many other professional power supply projects.
