Description
The Tenpower 21700-60XG is a next-generation tabless cylindrical cell engineered for the most demanding high-power applications. It delivers a massive 6000mAh capacity alongside a 40A continuous discharge (without triggering the 75°C thermal cutoff), or 60A continuous with thermal protection, and an astonishing 160A pulse capability (3 seconds). Built on Tenpower’s advanced full-tabless architecture, it achieves an ultra-low internal resistance of ≤3-5mΩ, minimizing heat generation and ensuring stable power delivery even under brutal loads. This cell is purpose-built for professional power tools, high-performance drones and eVTOL, e-bikes, and demanding DIY battery pack projects. Available in Flat Top, Button Top, Nickel Tab, and Pre-wired options, with 2, 4, 6, 8, and 10 pack options to suit your needs.
Key Features
6000mAh High Capacity + High Power: Defies the traditional trade-off between energy and power. Enjoy extended runtime without sacrificing peak current output.
40A Continuous (No Thermal Cutoff) / 60A Continuous (75°C Cutoff): The official rating distinguishes between a conservative, cooler-running 40A continuous discharge and a 60A continuous discharge that engages thermal protection at 75°C. This gives you flexibility depending on your thermal management design.
160A Pulse Discharge (3s): Massive burst capability for motor startups, drone takeoffs, and sudden load surges.
Ultra-Low Internal Resistance (≤3-5mΩ): Full-tabless architecture drastically reduces heat and voltage sag, maintaining stable output under heavy continuous loads.
Wide Operating Temperature Range: Reliable discharge from -20°C to 60°C (discharge), with stable performance even in cold conditions.
Multiple Terminal Options: Flat Top for standard spring-contact devices and spot-welding; Button Top for devices requiring a raised positive terminal; Nickel Tab and Pre-wired with Leads for custom high-current battery pack assembly.
Multiple Pack Options: Available in 2, 4, 6, 8, and 10 packs, ideal for building power tool packs, drone battery modules, or e-bike packs.

Applications
Recommended For:
Professional Power Tools: Angle grinders, circular saws, rotary hammers, and heavy-duty drills. The 40A/60A continuous rating and 6000mAh capacity provide both power and runtime for continuous professional use.
High-Performance Drones & eVTOL: The 160A pulse handles aggressive throttle inputs, while the tabless design ensures stable voltage and thermal management during demanding flight maneuvers.
E-Bikes & E-Scooters: Build high-capacity, high-power battery packs with fewer parallel cells needed. Always use a quality BMS.
High-Power DIY Battery Packs: Spot welders, portable power stations, and custom high-current projects where both energy density and power output are critical.
Not Recommended For:
Low-Power Long-Runtime Devices: Solar lights, sensors, and standard USB power banks. The extreme performance is wasted; choose a lower-cost, high-capacity cell instead.
18650-Only Devices: This is a 21700 cell (21.5mm x 70.5mm) and will not physically fit.
FAQ
Q1: Is the continuous discharge 40A or 60A?
A: Both figures are correct, but under different conditions. The cell is rated for 40A continuous without triggering the 75°C thermal cutoff, which is the recommended continuous load for cooler operation and longer cycle life. It can deliver 60A continuous with the 75°C thermal cutoff active. For most applications, design around 40A continuous for optimal reliability. The pulse capability is 160A for 3 seconds.
Q2: What is tabless technology and why does it matter?
A: A tabless (full-tabless) cell eliminates the thin metal tabs that connect the electrode layers. Instead, the entire electrode edge connects directly to the terminal. This dramatically lowers internal resistance (≤3-5mΩ), reduces heat generation, and allows much higher currents with less voltage sag. It is essential for high-drain applications like power tools and drones.
Q3: Can I use this battery for power tools?
A: Yes. The 21700-60XG is specifically designed for next-generation professional power tools. Its combination of 6000mAh capacity and high continuous discharge makes it ideal for angle grinders, saws, and other heavy-duty tools. Ensure your tool's battery pack is designed for 21700 cells and uses a proper BMS.
Q4: Do I need a special charger for this cell?
A: No special charger is required beyond a quality lithium-ion charger designed for 3.6V/4.2V cells. The cell supports up to 16A charge current, but charging at a lower rate (e.g., 3-6A) will extend cycle life. Always use a charger with proper CC-CV algorithm and 4.2V cutoff.
Q5: Which terminal type should I choose?
A: Choose Flat Top for standard spring-contact devices and spot-welding battery packs. Choose Button Top for devices with recessed battery compartments. Choose Nickel Tab or Pre-wired for custom high-current battery pack assembly.
Q6: How many batteries come in one pack?
A: This product is available in 2, 4, 6, 8, and 10 pack options. Please select your desired quantity from the dropdown menu before adding to cart.
