Power your high-drain devices with genuine bulk Samsung 30Q cells! The Samsung 30Q (INR18650-30Q) is widely regarded as the "Holy Grail" of 18650 batteries. It strikes the perfect balance between capacity and discharge rate: offering a massive 3000mAh capacity with a stable 15A continuous discharge. This makes it the ultimate choice for high-wattage regulated mods, tactical flashlights, and balanced DIY battery packs that require both endurance and instantaneous power.
This listing offers flexible bulk packaging (from 10 to 100 pieces) and five terminal options to perfectly suit your specific project needs:
Flat Top: For modern devices (flashlights, DIY packs, e-bikes).
Button Top: For older equipment with spring-loaded contacts.
Nickel Tab: Pre-welded with nickel strips for easy, solder-free DIY battery pack assembly.
Protected Top: With a built-in safety board for consumer electronics.
Pre-wired with Leads: Pre-soldered with red/black wires for plug-and-play replacements.
( Important: Please note that Protected Top and Pre-wired with Leads versions are 2-3mm longer than the standard Flat Top. Please check your device or pack's clearance before ordering!)
The "Holy Grail" of 18650 Cells: Perfectly balances 3000mAh capacity with 15A continuous discharge, providing both long runtime and high-power output.
True 15A High-Drain Performance: Delivers the power needed for high-wattage regulated mods (60-100W), tactical flashlights, and heavy-duty electronics.
Flexible Bulk Packaging (10-100 pcs): Choose the exact quantity you need. Our tiered pricing system rewards larger orders with automatic discounts.
Five Terminal Options: Flat Top, Button Top, Nickel Tab, Protected Top, and Pre-wired with Leads – perfect for any device, DIY project, or commercial assembly.
Authentic Samsung Quality: Premium-grade INR18650-30Q cells, ensuring exceptional cycle life and voltage stability. 100% genuine cells, NOT rewrapped or recycled.

Portable Power Stations & Outdoor Gear: Camping lights, heated jackets, portable fans, and similar moderate-drain electronics.
Q1: What is the difference between the five terminal options?
A1: Flat Top fits most modern devices. Button Top is for older spring-loaded devices. Nickel Tab is pre-welded for DIY pack assembly. Protected Top adds a safety circuit board (longer length). Pre-wired with Leads comes with red/black wires for direct replacement.
Q2: Do you offer wholesale/bulk discounts for 50+ pcs?
A2: Yes! Our pricing is designed to reward bulk buyers. Automatic tiered discounts apply at higher quantities (50, 80, and 100 pcs), making it cost-effective for businesses and project builders.
Q3: What is the continuous discharge rating?
A3: The official continuous discharge rating is 15A. This is the number on Samsung's own datasheet. Short-duration pulse discharges can reach slightly above 15A, but 15A is the real design ceiling for safety and longevity.
Q4: Does this battery have a protection circuit (PCB/BMS) built-in?
A4: No, standard cells are unprotected. However, we offer a Protected Top variant that includes a built-in safety circuit for consumer electronics. If you are building a battery pack, we recommend using a separate BMS (Battery Management System).
Q5: What is the difference between the Samsung 30Q and the Samsung 35E?
A5: The 30Q offers 3000mAh capacity with 15A discharge (balanced for high power). The 35E offers 3500mAh capacity with 8A discharge (designed for long runtime). If you need sustained high current, choose the 30Q. If you need maximum runtime, choose the 35E.
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.
