Key Features
-
6200mAh High Capacity – Provides approximately 24% more runtime than a 5000mAh 21700 cell and nearly 77% more energy than a standard 3500mAh 18650. Ideal for applications where maximizing runtime between charges is the top priority.
-
15A Continuous Discharge (CDR) – Stable, reliable power for high-output LED flashlights, fast-charging USB 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. 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 24800mAh power bank with four cells in parallel, power multiple high-output flashlights, or create a compact off-grid energy storage bank.
Parameters
Applications
Recommended For
-
High-Output 26650 LED Flashlights & Searchlights: The 15A CDR handles turbo modes with ease, while the 6200mAh capacity provides hours of bright illumination. Perfect for search and rescue, security, and outdoor adventures.
-
Massive-Capacity USB Power Banks: Build a 24800mAh power bank with four cells in parallel—enough to charge a smartphone over five times. The 15A rating supports 45W–65W USB-C PD fast charging.
-
Portable Bluetooth Speakers & Outdoor Audio: High-power speakers demand solid current for amplifiers. The K62 delivers clean power for distortion-free sound at high volumes, with the endurance for all-day music.
-
Medical Devices & Portable Monitors: Extended runtime and stable voltage output for critical equipment requiring uninterrupted power.
-
Off-Grid Energy Storage & Solar Banks: Low-current, long-duration energy storage with fewer cells needed than 21700 or 18650 packs.
-
DIY High-Capacity Projects: Robotics, backup power systems, and any project where maximum energy density is required.
Not Recommended For
-
18650 or 21700 Devices: The 26650 has a larger diameter (26.5mm vs. 18mm/21mm) and will not fit. Always check your device's battery compartment specifications.
-
High-Power Vaping / Mechanical Mods: Require 20–35A continuous discharge; 26650 is also uncommon in vaping devices.
-
Cordless Power Tools: Typically require 20–40A continuous current. Use dedicated high-drain cells like the Vapcell P54 (20A) for power tool applications.
-
RC Cars, Drones & Weight-Sensitive Applications: 26650 cells are heavier than 18650/21700 alternatives.
FAQ
Q: Is this a 26650 battery? Will it fit my 18650 or 21700 device?
A: Yes, the K62 is a 26650 cell with a diameter of approximately 26.5mm. It will not fit in devices designed for 18650 (18mm) or 21700 (21mm) cells. Only use this battery in devices specifically designed for the 26650 form factor. Please check your device's manual or measure the battery compartment before ordering.
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 require 20–35A continuous current and are typically designed for 18650 or 21700 cells. Power tools require 20–40A continuous. The K62's CDR is 15A. Using it in such devices will cause severe voltage sag, overheating, and potential damage. For these applications, use dedicated high-drain cells.
Q: Can I build a power bank with these?
A: Absolutely. Four K62 cells in parallel provide approximately 24800mAh—enough to charge most smartphones 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.
