This product listing offers the genuine XTAR 18650H 2600mAh 30A high-drain lithium-ion power cell (available in flexible pack sizes of 1, 2, 3, 4, 5, or 10 batteries). This is a bare, flat-top cell engineered for extreme high-drain applications. Delivering a true 2600mAh capacity and a massive 20A continuous discharge (30A pulse) , it provides explosive and sustained power for demanding loads. With an ultra-low internal resistance of ≤20mΩ, it ensures minimal voltage drop under heavy stress. Designed without a built-in protection PCB to maximize conductivity and reduce heat, it is the preferred choice for DIY custom battery pack builders, high-wattage electronic cigarette enthusiasts, and RC racing hobbyists. Whether you need one cell or a bulk supply, choose the pack size that suits your custom assembly needs.
Extreme High-Drain Performance: Delivers a robust 20A continuous discharge and 30A maximum pulse discharge, providing the surge current needed for heavy mechanical loads and rapid acceleration.
Ultra-Low Internal Resistance (≤20mΩ): Minimizes voltage drop during high-current discharge, ensuring stable power output under heavy load for better device efficiency.
Raw Flat Top Bare Cell: Features a flat top positive terminal and no built-in protection PCB. This design minimizes internal resistance, maximizes discharge efficiency, and is the standard form factor for spot-welding custom battery packs.
Premium International Cell Technology: Utilizes high-performance cells on par with industry-leading NPE/Molicel standards, providing superior cycle stability and long service life.
Industrial Grade Safety: Built with a high-strength stainless steel shell and 3 integrated safety exhaust vents to safely release internal gases in extreme conditions, preventing battery swelling and explosion hazards.
500-Cycle Longevity: Retains over 80% of its 2600mAh original capacity even after 500 full recharge cycles, offering an extended service life.
Flexible Quantity Options: Available in 1, 2, 3, 4, 5, or 10-piece packs, allowing you to match your daily DIY usage or batch assembly needs.

Important Warning: This is a bare cell without a built-in protection PCB. It is intended for use in devices with integrated protection circuits (BMS) or custom battery packs. Not suitable for devices lacking over-discharge/short-circuit protection.
Custom Battery Pack Assembly: Ideal for spot welding 1S/2S/3S battery packs for modified electric power tools, upgraded scooters, and DIY power stations.
High-Performance RC Hobbies: Provides the high-pulse power needed for brushless motors in custom-built RC cars, fixed-wing aircraft, and 3D drones.
High-Output Custom Flashlights: Suited for DIY flashlight enthusiasts building high-lumen single-cell lights that require extremely low internal resistance.
High-Drain Power Banks & Storage: Used as core cells for building heavy-duty DIY power banks designed to charge laptops or power outdoor camping appliances.
Q1: What are the available pack options for this battery?
A1: You can purchase this bare cell in 1, 2, 3, 4, 5, or 10-piece packs. Please select the desired quantity from the variant options before checkout.
Q2: Why is this battery a "Flat Top" and without a protection board?
A2: This is a high-drain power cell. The flat top and lack of a protection board are intentional to minimize internal resistance, reduce heat generation, and allow for maximum power output. It is the preferred raw cell for spot-welding into custom battery packs, which usually have their own Battery Management System (BMS).
Q3: What is the best way to charge this battery?
A4: Because it lacks a protection board, you must use a high-quality external smart charger (like XTAR chargers) with precise 4.20V ± 0.05V cut-off and over-temperature monitoring. Never charge this battery directly inside a device that doesn't have a dedicated charging module.
Q4: What does the 30A pulse discharge mean in real use?
A5: In real-world terms, the 30A pulse means the battery can provide a brief, massive burst of power for a few seconds. This is crucial for rapid acceleration in RC cars, the initial spin-up of heavy brushless drone motors, or hitting the turbo mode on high-end custom flashlights.
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.

These XTAR 18650H cells outperform my aging Sony VTC5s. Lower IR, better cycle life, and more consistent voltage under load.
The 20A CDR with 30A pulse gives me confidence. I never push past 25A, but knowing the headroom is there is reassuring.
The flat top makes perfect contact in my hybrid mod. No arcing on the positive terminal. XTAR designed these right.
I've dropped these, re-wrapped them, and they still perform. The metal can is thick. No dents after months in tube mods.
If you build low and need reliable current, get these. The 2600mAh capacity is honest and the 30A pulse handles my 0.12¦¸ builds.
