Lithium Ion Cylindrical Battery 3.7V - 18650 Cell 2500mAh 10C

High-Performance 10C Discharge Capability

The PKCELL ICR18650 2500mAh 3.7V Lithium-Ion cell is designed for heavy-duty electronic systems that demand substantial continuous power output. Boasting a massive 10C continuous discharge rating, this cell is capable of delivering up to 25A continuously without excessive voltage drop or overheating. It provides an impressive balance of high discharge current and dense energy storage for high-drain hardware builds.

Technical Specifications and Performance Metrics

Operating at a nominal voltage of 3.7V (4.2V peak charge, 2.75V discharge cutoff), this battery yields a reliable 2500mAh energy capacity. The low internal impedance ensures efficient energy transfer during aggressive duty cycles, extending overall operational runtime and suppressing internal thermal build-up during rapid discharge events.

Recommended Applications

Engineered for versatility, this high-drain 18650 cell is ideal for assembling multi-cell battery packs used in electric mobility solutions such as e-bikes and scooters, high-intensity tactical lighting, portable power tools, unmanned aerial vehicles (UAVs), robotics, and high-performance radio-controlled devices.

Crucial Safety Warning and Handling Precautions

PLEASE NOTE: This is an unprotected raw industrial lithium-ion cell lacking built-in PCB protection or an integrated Battery Management System (BMS). Using an unprotected cell in a device expecting a protected battery presents severe operational risks including fire or permanent damage. Users must ensure that appropriate external BMS protection, over-current cutoff, thermal monitoring, and proper cell balancing are implemented during pack integration and charging. Review your hardware specifications thoroughly before installation.
