Overview
The TENPOWER INR21700-60XG is a premium high-energy, high-power lithium-ion cell engineered for advanced mobility, industrial, and energy storage applications where conventional high-energy cells fall short. Achieving approximately 300 Wh/kg gravimetric energy density alongside a 60A continuous discharge rating and peak currents above 160A, the 60XG operates well outside the performance envelope typically associated with a 6000mAh cylindrical cell. Its NCA cathode and graphite/silicon carbide anode chemistry, combined with an AC internal resistance of less than 3mΩ, deliver stable voltage response and efficient energy transfer under demanding load conditions. Robust construction and high cycle durability make the INR21700-60XG a trusted choice for professional battery pack designers and engineers working at the frontier of cylindrical lithium-ion cell technology.
Applications / Uses
- Electric vehicles and high-performance mobility platforms
- Professional battery pack manufacturing and advanced pack engineering
- Industrial and heavy-duty power tools requiring high continuous and peak current output
- Robotics, automation equipment, and AGV systems
- Energy storage, backup power systems, and high-drain UAV applications

⚠ Important Safety Warnings
Improper handling or misuse of this lithium-ion battery can result in FIRE, EXPLOSION, or THERMAL RUNAWAY, causing personal injury, property damage, or death. Users must read and follow all safety guidelines before purchase and use. Click here to review the full safety guidelines.
- Critical Warning: Never carry loose batteries in your pocket, purse, or bag. Loose batteries can come into contact with metal objects like keys or coins, causing a short circuit, which may result in severe burns, fire, or explosion. Always store or transport batteries in a protective case.
- Intended Use: This battery is designed for integration into protected battery packs with a Battery Management System (BMS) or Protection Circuit Board (PCB). It is not intended for standalone use or for e-cigarettes, vaporizers, or similar devices.
-
Thermal Runaway: A chain reaction where heat from a failing battery
causes further overheating, potentially leading to fire or explosion.
- Causes: Overcharging, short circuits, physical damage, or exposure to high temperatures.
- Prevention: Use a smart charger, avoid damage, and store batteries in a cool, dry place.
- Storage & Transport: Always store batteries in protective cases to prevent accidental contact with metal objects. Never store loose batteries in pockets, purses, bags, or near conductive materials.
- Inspection: Do not use if the PVC wrapper, terminal insulator, or casing is damaged, dented, leaking, or bulging. Continued use could result in failure, fire, or explosion.
- Charging: Use a smart charger specifically designed for lithium-ion batteries and ensure the charger's voltage matches the battery's specifications. Never overcharge, over-discharge, or leave unattended while charging.
-
Prohibited Activities:
- Do not expose the battery to extreme heat, fire, or liquids.
- Do not short circuit, puncture, crush, or modify the battery.
- Do not charge or discharge beyond the manufacturer’s voltage range.
- Do not dispose of in regular trash—always recycle at approved facilities.
- Emergency Response: If a cell shows signs of thermal runaway (e.g., smoke, swelling, hissing, or heat), stop use immediately and, if it can be done safely, move it to a non-flammable surface (e.g., concrete or sand) away from combustible materials. Lithium-ion cells burn as Class B fires — use an ABC / dry-chemical fire extinguisher, or douse with large amounts of water to cool the cell and prevent the fire from spreading. Do not rely on a small spray; thorough cooling is required, and cells can reignite from residual heat, so monitor the area afterward. (Class D extinguishers are intended for lithium-metal batteries, not lithium-ion.) For any fire beyond a single small cell, evacuate and call emergency services.
