Applications
Recommended For
-
LED Flashlights & Headlamps: Perfect for regulated single-cell lights on medium to high modes. The 3000mAh capacity provides hours of steady illumination—ideal for camping, hiking, running, and professional inspection work.
-
High-Capacity USB Power Banks: Build a compact 6000mAh power bank with two cells in parallel. The 15A rating comfortably supports 18W USB-C PD fast charging. Great for daily carry and travel.
-
Portable Fans & Cooling Devices: Neck fans, handheld fans, and desk fans benefit from the extended runtime. Keep cool through hot workdays, outdoor events, or power outages.
-
Solar Garden Lights & Street Lights: Low-current, all-night operation. The 3000mAh capacity ensures consistent brightness from dusk until dawn.
-
Wireless Security Cameras & Smart Doorbells: Ultra-low standby power consumption with months of operation between charges. Reliable power for motion-activated recording.
-
Medical Devices & Portable Monitors: Stable, dependable power for equipment requiring uninterrupted operation within 15A limits.
Not Recommended For
-
High-Power Vaping / Mechanical Mods (>15A Continuous): Sub-ohm builds and high-wattage regulated mods typically require 20–35A continuous. Choose the Vapcell V30 (20A CDR) or K30 (30A CDR) for vaping applications.
-
Cordless Power Tools: Drills, saws, and impact drivers demand 20–40A continuous current. Use dedicated high-drain cells instead.
-
RC Cars, Drones & High-Drain Models: These require 20–30A+ continuous current. The G30 is engineered for capacity and endurance, not extreme current delivery.
-
FET-Driven Flashlights Exceeding 15A on Turbo: If your light's turbo mode pulls over 15A, select a higher-drain cell such as the Vapcell V30 to avoid performance loss.
FAQ
Q: What is the difference between the G30 and V30? Which should I choose?
A: The G30 is optimized for capacity and long runtime with a 15A CDR—ideal for flashlights, power banks, fans, and solar lights. The V30 is optimized for higher current output with a 20A CDR—better suited for vaping, high-output flashlights, and power tools. Choose the G30 if your device draws 15A or less and you want maximum runtime. Choose the V30 if you need 20A continuous for more demanding applications.
Q: Can I use this battery for vaping?
A: Only for low-to-medium power regulated mods drawing well under 15A. Most sub-ohm builds and high-wattage mods require 20–35A continuous. Using the G30 in such devices will cause severe voltage sag, rapid overheating, and potential battery damage. For vaping, we recommend the Vapcell V30 (20A CDR) or K30 (30A CDR).
Q: How much runtime can I expect compared to a 2500mAh cell?
A: The G30's 3000mAh capacity provides approximately 20% more runtime than a 2500mAh cell. In practical terms, a flashlight that runs for 5 hours on medium with a 2500mAh cell could run for about 6 hours with the G30. Every bit of extra capacity adds up over daily use.
Q: Can I build a power bank with these?
A: Absolutely. Two G30 cells in parallel provide approximately 6000mAh—enough to fully charge most smartphones at least once. The 15A per cell rating easily supports 18W USB-C PD fast charging. It is an excellent cell for DIY power bank projects.
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.
