Power your biggest projects with the Vapcell G50, a 21700 cell that combines a substantial 5000mAh capacity with a robust 15A continuous discharge. This 6-pack provides the perfect foundation for building high-capacity DIY power banks, e-bike range extender packs, solar energy storage banks, and powering a fleet of high-output LED flashlights. With 50% more current headroom than typical 10A high-capacity cells, the G50 handles demanding modes while delivering exceptional runtime. The flat top design ensures universal compatibility with spring-loaded contacts and simplifies spot-welding for custom battery packs. Whether you are assembling a 6S1P e-bike pack, a massive USB power bank, or upgrading all your 21700 flashlights, the Vapcell G50 delivers the balanced performance your projects demand.
5000mAh High Capacity – Provides approximately 43% more energy than a standard 3500mAh 18650 cell. Extended runtime for devices where frequent charging is inconvenient.
15A Continuous Discharge (CDR) – Delivers 50% more current than typical 10A high-capacity cells. Handles fast-charging power banks, bright flashlight turbo modes, and moderate e-bike loads without overheating.
Flat Top Design – Universally compatible with all standard 21700 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.
6-Pack Bulk Value – Perfect for building a 6S1P e-bike pack, a 30000mAh power bank (6 cells in parallel), or refreshing your entire flashlight collection. Matched cells ensure consistent pack performance.
Vapcell Quality Control – Each cell is tested and matched for consistent capacity and low internal resistance, ensuring reliable performance across the entire pack.

Recommended For
High-Output 21700 LED Flashlights: The 15A CDR provides ample headroom for turbo modes that would push 10A cells to their limit. Enjoy bright, consistent illumination with the endurance of 5000mAh capacity.
Massive-Capacity USB Power Banks: Build a 30000mAh power bank with six cells in parallel—enough to charge a smartphone over six times. The 15A rating comfortably supports 45W–65W USB-C PD fast charging.
Solar Energy Storage & Off-Grid Systems: Low-current, long-duration energy storage. The 5000mAh capacity per cell builds substantial energy reserves for solar light banks and small off-grid installations.
E-Bike Range Extender Packs: In multi-parallel configurations with a proper BMS, the 15A per cell supports 250W–500W motors. A 6S2P (12 cells) or larger pack provides excellent range. Always use matched cells and a properly rated BMS.
DIY Battery Projects & Portable Power Stations: Ideal for custom packs where balanced capacity and enhanced current capability are both needed.
Not Recommended For
High-Power Vaping / Mechanical Mods (>15A): These require 20–35A continuous. Use Vapcell T42 (35A) or K40 (30A) instead.
Heavy-Duty Cordless Power Tools: Angle grinders and circular saws demand 20–40A continuous. Use dedicated high-drain cells.
RC Cars, Drones & High-Drain Models: These require 20–30A+ continuous current.
Single-Cell E-Bike Applications: A single G50 cannot provide sufficient voltage or current. Always use a multi-series and parallel configuration with a BMS.
Q: How does the G50 compare to other Vapcell 5000mAh cells like the S50 or F50?
A: The G50 offers 5000mAh with a 15A CDR, identical in specs to the S50. It is part of Vapcell's high-capacity lineup with enhanced current capability. Compared to the F50 (5000mAh/10A), the G50 provides 50% more current headroom, making it more suitable for devices that occasionally demand higher power. If your application never exceeds 10A, the F50 offers the same capacity at a more affordable price.
Q: Can I build an e-bike battery with this 6-pack?
A: The 6-pack provides enough cells for a 6S1P 24V configuration (6 cells in series). For a typical 36V e-bike, you would need a 10S configuration (10 cells in series). For practical range and current handling, a 10S2P (20 cells) or 10S3P (30 cells) pack is recommended. The 15A per cell rating in a 10S2P configuration supports up to 30A total, suitable for 500W–750W motors. Always use a properly rated BMS, matched cells, and spot-welded nickel strips.
Q: Is this battery suitable for vaping or power tools?
A: No. Vaping devices and power tools require high continuous currents (typically 20–40A). The G50's CDR is 15A. Using it in such devices will cause severe voltage sag, rapid overheating, and potential battery damage. Use Vapcell T42 or K40 for those applications.
Q: What devices benefit most from the 15A CDR?
A: Any device that needs more current than a standard 10A high-capacity cell can comfortably provide: high-mode 21700 flashlights, 45W+ USB-C power banks, and multi-cell e-bike packs where higher per-cell current reduces the number of parallel strings needed.
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.
Free Shipping: Enjoy free shipping on all orders over $65. For orders under $65, the shipping cost is $8.99.
Delivery Time: Once shipped, orders typically arrive within 7–15 business days.
Easy Returns: We want you to be completely satisfied. If you're not, you can return your product within 30 days of receiving your order. Please ensure the items are unused and in their original condition. For return instructions, please contact our support team.
