🔋 18650 7S1P Battery Pack — 25.9V 2600mAh Rechargeable Li-ion Industrial Battery

Overview

This 18650 7S1P lithium-ion battery pack connects seven Grade A 18650 cells in series, delivering 25.9V / 2600mAh (67.34Wh) in a compact cylindrical blue PVC heat-shrink enclosure. The 25.9V output bridges the gap between standard 22.2V tool packs and 36V e-bike systems — making it the preferred choice for low-voltage electric scooters, light e-bikes, high-power cordless tools, brushless motor systems, and industrial automation equipment requiring stable sub-30V DC power. CE and UN38.3 certified, with full OEM customization available.
