Key Features
-
7000mAh Ultra-High Capacity – Among the highest capacity available in the 26650 form factor. Provides approximately 40% more energy than a 5000mAh 21700 cell and nearly double the capacity of a 3500mAh 18650. Perfect for applications where maximum runtime is non-negotiable.
-
15A Continuous Discharge (CDR) – Stable, reliable power for high-output LED flashlights, fast-charging power banks, portable speakers, and similar medium-drain devices. Sufficient for turbo flashlight modes and 45W+ USB-C PD charging circuits.
-
Flat Top & Button Top Options – Choose flat top for spring-contact devices and spot-welding custom packs, or button top for devices requiring a raised positive terminal for reliable contact.
-
Robust 26650 Form Factor – Physically larger than 18650 (18mm) and 21700 (21mm) cells at approximately 26.5mm diameter. Offers higher capacity per cell, reducing the number of cells needed in multi-cell projects. Always verify your device accepts 26650 before ordering.
-
Long Cycle Life – Retains over 80% of initial capacity after 500 charge/discharge cycles under recommended conditions, reducing long-term replacement costs.
-
4-Pack Convenience – Build a massive 28000mAh power bank with four cells in parallel, power multiple high-output flashlights, or create a compact off-grid energy storage bank with industry-leading energy density.

Applications
Recommended For
-
High-Output 26650 LED Flashlights & Searchlights: Perfect for large-frame flashlights designed for 26650 cells. The 7000mAh capacity provides days of continuous illumination on medium modes and hours on turbo. Ideal for search and rescue, cave exploration, and professional security.
-
Massive-Capacity USB Power Banks: Build a 28000mAh power bank with four cells in parallel—enough to charge a smartphone over five times. The 15A rating comfortably supports 45W–65W USB-C PD fast charging for laptops and tablets.
-
Portable Speakers & Outdoor Audio Gear: High-power Bluetooth speakers benefit from the 7000mAh capacity for all-day music at festivals, camping, and beach outings.
-
Off-Grid Energy Storage & Solar Banks: Low-current, long-duration storage. The 7000mAh per cell builds substantial reserves with fewer cells than 21700 or 18650 packs.
-
DIY High-Capacity Projects & Robotics: Ideal for custom battery packs where maximum energy density in a manageable form factor is required.
Not Recommended For
-
18650 or 21700 Devices: The 26650 is physically larger (26.5mm vs. 18mm/21mm) and will not fit in devices designed for smaller cells. Always check your device's battery compartment specifications.
-
High-Power Vaping / Mechanical Mods: These require 20–35A continuous discharge. The K70 is a high-capacity cell, not a high-drain cell. Use dedicated high-drain 18650/21700 cells instead.
-
Cordless Power Tools: Power tools typically require 20–40A continuous and use proprietary battery packs not compatible with bare 26650 cells.
-
RC Cars, Drones & Weight-Sensitive Applications: 26650 cells are heavier than 18650/21700, making them less suitable for weight-critical applications.
FAQ
Q: Is this a 26650 battery? What does that mean? Will it fit my device?
A: Yes, the K70 is a 26650 cell, which means it has a larger diameter of approximately 26.5mm compared to 18mm for 18650 and 21mm for 21700 cells. It will only fit devices specifically designed for 26650 batteries. Many high-output LED flashlights, large power banks, and portable speakers use 26650 cells. Please check your device's manual or measure the battery compartment before ordering.
Q: Can I use this in my 18650 or 21700 flashlight?
A: No. The 26650 is significantly thicker (26.5mm vs. 18mm/21mm) and will not physically fit into 18650 or 21700 battery compartments. Only use this cell in devices explicitly compatible with 26650 batteries.
Q: What is the difference between flat top and button top? Which should I choose?
A: Flat top cells have a completely flat positive terminal, ideal for devices with spring-loaded contacts and for spot-welding into custom battery packs. Button top cells have a raised positive nipple, required by some flashlights and devices for proper contact or reverse-polarity protection. Check your device's requirements before selecting.
Q: Can I use this battery for vaping or power tools?
A: No. Vaping devices and power tools require high continuous currents (typically 20–40A). The K70's CDR is 15A. Using it in such devices will cause severe voltage sag, rapid overheating, and potential battery damage. For these applications, use dedicated high-drain 18650 or 21700 cells.
Q: Can I build a massive power bank with these?
A: Absolutely. Four K70 cells in parallel provide approximately 28000mAh—enough to charge a smartphone over five times. The 15A per cell rating easily supports 45W–65W USB-C PD fast charging. With a quality power bank enclosure, this is one of the most compact ultra-high-capacity DIY power bank solutions available.
Q: How should I store these cells when not in use?
A: Store at 3.6–3.7V (approximately 40–50% charge) in a cool, dry place. Use non-conductive battery cases to prevent accidental short circuits. Avoid storing fully charged or deeply discharged for extended periods.
