Get versatile high-current power in a robust 26650 format with the Vapcell P54. This 2-pack delivers a solid 5400mAh capacity and a true 20A continuous discharge, making it an excellent choice for high-output LED flashlights, portable speakers, light-to-medium power tools, and DIY battery projects. Choose from flat top, button top, or protected button top to match your specific device requirements. The 26650 form factor is physically larger than 18650 and 21700 cells—always verify your device accepts 26650 before ordering. With excellent cycle life and Vapcell's trusted quality, the P54 provides dependable, long-lasting power for your demanding devices.
20A True Continuous Discharge (CDR) – Delivers stable, high-current output for power-hungry devices. Handles FET-driven flashlight turbo modes, power tool surges, and high-output speaker amplifiers with ease.
5400mAh Solid Capacity – Provides ample runtime for extended use. Balances capacity and current delivery for applications that need both endurance and power.
Multiple Top Options – Available in Flat Top (spring-contact devices and spot-welding), Button Top (devices requiring raised positive), and Protected Button Top (built-in overcharge/over-discharge/short circuit protection, longer length). Choose the right fit for your equipment.
Robust 26650 Form Factor – Larger diameter (26.5mm) than 18650 (18mm) and 21700 (21mm). Offers higher capacity and better heat dissipation. Always verify your device accepts 26650 before ordering.
Long Cycle Life – Retains over 80% of initial capacity after 500 charge/discharge cycles under recommended conditions.
2-Pack Convenience – Ideal for powering a flashlight and a speaker, or rebuilding a small tool battery pack.

Recommended For
High-Output 26650 LED Flashlights & Searchlights: The 20A CDR handles turbo modes with ease, while the 5400mAh capacity provides hours of bright illumination. Perfect for search and rescue, security, and outdoor adventures.
Portable Bluetooth Speakers & Audio Systems: High-power speakers demand strong current for amplifiers. The P54 delivers clean power for distortion-free sound at high volumes.
Light-to-Medium Cordless Power Tools: Impact drivers, drills, and small saws benefit from the 20A surge capability. Ideal for rebuilding tool battery packs when used with matched cells and a proper BMS.
DIY High-Drain Battery Packs: Robotics, portable power stations, and any project requiring balanced high current and solid capacity.
High-Capacity USB Power Banks: Build a 10800mAh power bank with two cells in parallel. The 20A rating supports 60W+ USB-C PD fast charging.
Not Recommended For
18650 or 21700 Devices: The 26650 has a larger diameter (26.5mm vs. 18mm/21mm) and will not fit. Always check your device's battery compartment specifications.
Heavy-Duty Power Tools (Angle Grinders, Rotary Hammers): These demand 30–40A continuous. Use dedicated ultra-high-drain cells.
Extreme Competition Vaping / Mechanical Mods: Require 25–35A continuous; 26650 is also uncommon in vaping devices.
Ultra-Compact or Weight-Sensitive Devices: 26650 cells are heavier and bulkier than 18650/21700 alternatives.
Q: What is the difference between the three top options?
A: Flat Top – completely flat positive terminal, best for devices with spring-loaded contacts and for spot-welding custom packs. Button Top – raised positive nipple, required by some flashlights and devices for proper contact. Protected Button Top – includes a built-in circuit that prevents overcharge, over-discharge, and short circuits, but limits max current to ~10–15A and adds approximately 3–5mm in length. Check your device requirements before selecting.
Q: Will this battery fit my 18650 or 21700 flashlight?
A: No. The 26650 format is physically larger (26.5mm diameter) than both 18650 (18mm) and 21700 (21mm). It will only fit devices specifically designed for 26650 cells. Please measure your device's battery compartment or consult the manufacturer's specifications.
Q: Can I use the protected version in high-drain devices?
A: The protected version includes a safety circuit that typically limits current to 10–15A. If your device draws more than this (e.g., a high-output flashlight on turbo or a power tool), the protection may cut off power. For applications requiring the full 20A CDR, use the flat top or button top version and ensure your device has its own protection.
Q: Is this battery suitable for vaping?
A: No. Most vaping devices require 20–35A continuous and are designed for 18650 or 21700 cells. The P54 is a 26650 cell and is not recommended for vaping applications.
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.

The Vapcell wrapper on the P54 has held up well to many insertions into my various devices without any damage.
The Vapcell P54 offers the perfect combination of 5400mAh and 20A. Ideal for users who need both runtime and high-drain capability.
Whether you need runtime or power, the Vapcell P54 delivers both. The multiple top options make it compatible with all devices.
I ran a discharge test at 20A and the temperature stayed under 60¡ãC. The P54 handles high current with impressive thermal management.
The button top on these P54 cells is solidly attached. It does not deform under spring pressure in my lights.
