2-Pack Vapcell 18350 850mAh 3.7V 10A CDR Flat Top Battery – Ultra High Drain for Turbo Flashlights, Mini Tools
Description
Description
Unlock extreme power in the most compact form factor with the Vapcell 18350 850mAh high-drain cell. This 2-pack delivers a true 10A continuous discharge at 3.7V, making it the go-to choice for short-body FET turbo flashlights, stubby mini power tools, and high-power laser pointers. At only 35mm long—30mm shorter than an 18650—it fits where standard cells simply cannot. The flat top design ensures broad compatibility with spring-loaded contacts. Important: This is an unprotected high-drain cell. Always use with care, never short-circuit, and ensure your device has appropriate protection. With ultra-low internal resistance and Vapcell's trusted quality, this cell provides explosive power in the palm of your hand.
Key Features
-
10A True Continuous Discharge (CDR) – Delivers stable, high-current output for demanding devices. Handles FET-driven turbo modes, coil ramp-up, and motor start-up surges without dangerous voltage sag. Far outperforms typical 5–7A 18350 cells.
-
850mAh Optimized Capacity – Balanced for high-drain use. Provides usable runtime while maintaining the ability to deliver 10A continuously. Ideal for applications that prioritize power over maximum capacity.
-
Ultra-Compact 18350 Form Factor – Same diameter as an 18650 (18mm) but only 35mm long—30mm shorter. Perfect for stubby flashlights, compact mods, and devices with tight battery compartments. Always verify your device uses 18350 cells before ordering.
-
Flat Top Design – Universally compatible with devices featuring spring-loaded contacts. The flat terminal also simplifies spot-welding for custom battery packs.
-
Ultra-Low Internal Resistance – Minimizes heat generation and voltage drop under load, ensuring maximum power reaches your device when it needs it most.
-
Unprotected Cell – Designed for high-drain applications where unrestricted current flow is essential. Must use with care: never short-circuit, over-discharge below 2.5V, or overcharge above 4.2V.
-
2-Pack Convenience – Perfect for powering a stubby flashlight and keeping a charged spare ready.

Applications
Recommended For
-
Stubby FET Turbo Flashlights (18350 Compatible): Push your ultra-compact EDC torch to its absolute limit. The 10A CDR delivers significantly brighter turbo modes than standard 5–7A 18350 cells. Perfect for enthusiasts seeking maximum output from short-body lights.
-
Short-Body : Suitable for compact mechanical and regulated mods that use 18350 cells. The 10A rating provides a safe operating margin for builds above approximately 0.4Ω.
-
Mini Power Tools & Electric Screwdrivers: Many compact precision screwdrivers and small electric drills use 18350 cells and benefit from the high current capability for stronger torque.
-
High-Power Laser Pointers: Compact handheld lasers that require significant current in a small form factor.
-
DIY Compact High-Drain Packs: Build small battery packs for projects where space is limited but power demands are significant.
Not Recommended For
-
18650 or 21700 Devices: The 18350 is 30mm shorter (35mm vs. 65mm) and will not fit in devices designed for larger cells. Always check your device's battery compartment specifications.
-
Long-Runtime Low-Power Devices: With 850mAh capacity, devices like portable fans, wireless mice, and sensors are better served by a high-capacity 18350 cell like the Vapcell F14 (1400mAh/3A).
-
Applications Requiring Sustained >10A: For continuous currents above 10A, use a higher-drain cell in a larger form factor.
FAQ
Q: Is this battery the same size as an 18650? Will it fit my standard flashlight?
A: No. This is an 18350 cell, which has the same diameter as an 18650 (18mm) but is only 35mm long—30mm shorter than the standard 65mm 18650. It will only fit in devices specifically designed for 18350 cells, such as stubby or short-body flashlights. Always check your device's manual or measure the battery compartment before ordering.
Q: Why is the capacity only 850mAh? I've seen 1400mAh 18350 cells.
A: This cell is engineered for maximum current output, not maximum capacity. The 850mAh is a trade-off to achieve the 10A continuous discharge and ultra-low internal resistance. For applications that need longer runtime at lower currents (≤3A), consider a high-capacity 18350 like the Vapcell F14 (1400mAh/3A).
Q: Can I use this battery for vaping? What resistance is safe?
A: Yes, for compact mods designed for 18350 cells. With a 10A CDR at 3.6V nominal, it can safely power builds down to approximately 0.4Ω, providing a comfortable safety margin. Always calculate your actual current using Ohm's law and never exceed 10A continuous.
Q: Will this battery get hot during use?
A: At 10A continuous discharge, this cell will become noticeably warm. This is normal for a high-drain cell of this size, but you should ensure adequate ventilation and avoid using it in completely sealed devices without any heat dissipation. If the battery becomes too hot to touch comfortably, reduce the load or allow it to cool down.
Q: What does "unprotected" mean? Is it safe?
A: An unprotected cell does not have a built-in circuit board that prevents overcharge, over-discharge, or short circuits. This allows unrestricted current flow, which is essential for high-drain applications. You must rely on your device's built-in protection features or handle the cell carefully. Never short-circuit the terminals, never discharge below 2.5V, and always use a quality charger.
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—this is especially important for unprotected cells. Avoid storing fully charged or deeply discharged for extended periods.
