With an ultra-low internal resistance of approximately 12mΩ, the P30B delivers minimal voltage sag and maximum punch, all while giving you more runtime than typical high-drain cells. Available in Flat Top, Button Top, Nickel Tab, and Pre-wired configurations, with 2, 4, 6, 8, and 10 pack options. When you need both endurance and extreme current, the P30B is the professional's choice.
Key Features
3000mAh + 30A Balanced Performance: The perfect sweet spot between high capacity and high drain. Enough energy for longer sessions, enough current for demanding builds and tools.
30A True Continuous Discharge: Handles sub-ohm vaping, power tool start-up surges, and FET turbo flashlights without breaking a sweat. No pulsing, no guesswork.
Ultra-Low Internal Resistance (~12mΩ): Minimizes heat generation and voltage drop, ensuring consistent performance and longer cell life even under heavy loads.
Multiple Terminal Options: Flat Top for spring-contact devices and spot-welding packs; Button Top for devices requiring a raised positive terminal; Nickel Tab and Pre-wired for custom battery pack assembly.
Molicel Genuine Quality: Manufactured by one of the most trusted names in high-drain lithium cells, with rigorous testing and consistent batch performance.
Multiple Pack Options: Available in 2, 4, 6, 8, and 10 packs, ideal for dual-battery mods, tool pack rebuilds, or small high-current RC packs.

Applications
Recommended For:
High-Power Vaping: Mechanical mods and high-wattage regulated devices with sub-ohm builds (safely down to ~0.13Ω at 3.6V). The 3000mAh capacity provides noticeably longer vaping sessions compared to 2500-2600mAh cells.
Cordless Power Tools: Impact drivers, drills, and wrenches when used in properly built battery packs with a BMS. The 30A rating handles startup surges effortlessly.
High-Output Flashlights: FET-driven or direct-drive hot-rod lights with turbo modes pulling 20-30A. Enjoy both extreme brightness and extended runtime.
RC Cars, Boats & Airsoft: Competitive models that need instant burst currents and benefit from the extra capacity for longer play.
DIY High-Current Projects: Spot welders, portable jump starters, and any application where balanced capacity and current matter.
Not Recommended For:
Ultra-long runtime low-power devices: If your device draws less than 5A continuously, a 3500mAh high-capacity cell (e.g., Panasonic NCR18650GA) will provide longer runtime.
Standard USB power banks: The high-current capability is wasted; a cheaper high-capacity cell is more suitable.
Devices with extremely tight battery compartments: Button top versions add slight length; verify fit before ordering.
FAQ
Q1: What makes the P30B special compared to other high-drain cells?
A: Most high-drain 18650s sacrifice capacity for current (e.g., 2600mAh for 35A). The P30B gives you a genuine 30A while keeping 3000mAh, meaning you don't have to choose between power and runtime. It's the ideal "all-day" high-performance cell.
Q2: Can I use this for vaping? What resistance is safe?
A: Yes, the P30B is excellent for mechanical mods and regulated high-wattage devices. With a 30A continuous limit and 3.6V nominal, it can safely fire builds down to approximately 0.13Ω, leaving a comfortable safety margin. Always calculate your actual current using Ohm's law.
Q3: Should I choose flat top or button top?
A: Flat top is the standard for most spring-loaded flashlights, chargers, and for spot-welding battery packs. Button top is needed for some devices that require a raised positive contact for reverse-polarity protection or specific battery holders. Check your device's requirements before ordering. Nickel Tab and Pre-wired options are ideal for custom battery pack assembly.
Q4: Is this battery protected?
A: No, the P30B is an unprotected cell, which is standard for high-drain applications to allow full current flow. Your device must have its own low-voltage protection, or you must use an external BMS when building multi-cell packs.
Q5: How should I store these cells long-term?
A: Store at 3.6-3.7V (about 40-50% charge) in a cool, dry place inside a non-conductive case. Avoid storing fully charged or fully discharged for weeks or months.
Q6: How many batteries come in one pack?
A: This product is available in 2, 4, 6, 8, and 10 pack options. Please select your desired quantity from the dropdown menu before adding to cart.
