Product Description
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.
Key Features
-
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.

Frequently Asked Questions (FAQ)
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.
