This 4-pack provides approximately 3% more capacity than standard 3500mAh cells, making it an excellent choice for regulated LED flashlights, portable fans, power banks, solar lights, and DIY projects. The flat top design ensures broad compatibility with spring-loaded contacts and simplifies spot-welding for custom battery packs. With Vapcell's rigorous cell matching and long cycle life, the V2.0 delivers consistent, reliable power for all your everyday medium-drain devices. Important: This is a 10A continuous cell. It is not suitable for high-power vaping or other applications exceeding 10A.
Key Features
-
3600mAh High Capacity – Delivers approximately 3% more runtime than standard 3500mAh cells. Provides significantly longer operation between charges for medium-drain devices.
-
10A Continuous Discharge (CDR) – Stable, reliable power output for LED flashlights, USB power banks, portable fans, and similar devices. Sufficient for regulated flashlight turbo modes and fast-charging power bank circuits.
-
Flat Top Design – Universally compatible with all standard 18650 spring-contact chargers, flashlights, and battery trays. The flat terminal is ideal for spot-welding nickel strips in custom battery packs.
-
Long Cycle Life – Retains over 80% of initial capacity after 500 charge/discharge cycles under recommended conditions, reducing long-term replacement costs.
-
4-Pack Value – Ideal for building a compact 7200mAh power bank (two cells in parallel, two sets), keeping spares for your flashlights, or powering a family of devices.
-
Vapcell Quality Control – Each cell is tested and matched using authentic high-quality cells, ensuring consistent capacity and low internal resistance batch after batch.
Parameters
Applications
Recommended For
-
LED Flashlights & Headlamps: Perfect for regulated single-cell lights on medium to high modes. The 3600mAh capacity provides hours of steady illumination for camping, hiking, and professional use.
-
High-Capacity USB Power Banks: Build compact power banks with excellent energy density. A 2-cell parallel configuration yields approximately 7200mAh, easily supporting 18W fast charging.
-
Portable Fans & Cooling Devices: Neck fans, handheld fans, and desk fans benefit from the extended runtime. Ideal for hot climates, outdoor events, and daily commuting.
-
Solar Garden Lights & Street Lights: Low-current, all-night operation with consistent brightness from dusk until dawn.
-
Wireless Security Cameras & Smart Doorbells: Ultra-low standby power consumption with months of operation between charges.
-
DIY IoT & Sensor Projects: Arduino, ESP32, and Raspberry Pi portable projects benefit from the generous energy reserve for extended field deployment.
-
Medical Devices & Portable Monitors: Reliable, stable power for equipment requiring uninterrupted operation within 10A limits.
Not Recommended For
-
High-Power Vaping / Mechanical Mods (>10A): This is a 10A continuous cell. Sub-ohm builds and high-wattage regulated mods typically require 15–35A continuous. Using this cell will cause severe voltage sag, rapid overheating, and potential battery damage. For any vaping device drawing over 10A, use a dedicated high-drain cell such as the Vapcell K30 (30A CDR).
-
Cordless Power Tools: Drills, saws, and impact drivers demand 15–40A continuous current. Use dedicated high-drain cells instead.
-
RC Cars, Drones & High-Drain Models: These require 20–30A+ continuous current. This cell is engineered for capacity, not extreme current delivery.
-
FET-Driven Flashlights Exceeding 10A on Turbo: If your light pulls over 10A on maximum mode, select a higher-drain cell to avoid performance loss and potential damage.
FAQ
Q: What is the actual CDR of this battery? I've seen "35A" mentioned elsewhere.
A: This Vapcell V2.0 cell has a Continuous Discharge Rating (CDR) of 10A. The "35A" figure that appears on some listings is a pulse rating—a short burst capability measured in seconds, not a continuous rating. Never design your system based on pulse ratings. For continuous loads above 10A, use a dedicated high-drain cell like the Vapcell K30 (30A CDR).
Q: Can I use this battery for vaping?
A: Only for very low-power vaping devices drawing well under 10A. Most sub-ohm tanks, rebuildable atomizers, and high-wattage regulated mods require 15–35A continuous. Using a 10A cell in such devices will cause dangerous voltage sag, severe overheating, and potential battery failure. For vaping, we strongly recommend dedicated high-drain cells like the Vapcell K30 (30A CDR).
Q: How does the 3600mAh compare to 3500mAh cells?
A: The 3600mAh V2.0 provides approximately 3% more capacity than standard 3500mAh cells. While the difference is modest, every extra bit of runtime counts in devices that run for hours. It sits as a slight upgrade over 3500mAh cells while typically being more affordable than 4000mAh flagship models.
Q: What devices are best suited for this cell?
A: Any device drawing under 10A where extended runtime is valued: LED flashlights on medium/high, USB power banks, portable fans, solar lights, wireless security cameras, smart doorbells, and long-running IoT sensor nodes. It is an excellent everyday high-capacity cell.
Q: Can I build a power bank with these?
A: Absolutely. Two cells in parallel provide approximately 7200mAh—enough to fully charge most smartphones about 1.5 times. The 10A per cell rating easily supports 18W USB-C PD fast charging. With the 4-pack, you can build two compact power banks or one larger capacity unit.
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.
