Uncompromising power for your most demanding devices. The EVE 20P 18650 Battery 2000mAh 20A High Drain is engineered for applications that demand maximum current output in a compact 18650 form factor. Whether you're pushing the limits with a sub-ohm build, driving a cordless impact wrench through tough materials, or racing a high-speed drone through tight courses, this battery delivers the raw, sustained power you need. With a 20A continuous discharge and 2000mAh capacity, it strikes the perfect balance between explosive output and practical runtime. This listing offers Flat Top, Button Top, and Nickel Tab versions, giving you the flexibility to choose the right terminal type for your specific setup. Trust EVE quality – power your passion.
20A Continuous Discharge: Stable, high-current output designed for sub-ohm heavy-duty power tools, and racing drones. Low internal resistance means less heat and more power delivered to your device.
2000mAh Capacity: Optimized for high-drain applications. Provides enough runtime for extended sessions without sacrificing the power output that high-performance devices demand.
Three Terminal Options – Choose Your Fit:
Flat Top – Standard flat positive terminal, compatible with most modern flashlights, and tool batteries.
Button Top – Raised positive terminal (like a standard AA battery), required for older devices and specific battery holders with spring-loaded contacts.
Nickel Tab – Pre-welded nickel strips on the positive and negative terminals, ready for solder-free DIY battery pack assembly – perfect for building custom tool packs or drone batteries.
Versatile Compatibility: Designed to work with sub-ohm cordless impact wrenches, racing drones, high-lumen flashlights, and other high-drain devices.
Rechargeable & Eco-Friendly: Can be recharged hundreds of times, reducing waste and saving money compared to disposable batteries.
Trusted EVE Quality: Premium ICR cells from a world-leading lithium-ion manufacturer, ensuring excellent cycle life, safety certifications, and consistent voltage stability under heavy loads.

Cordless Impact Wrench: Heavy-duty power tools that need burst power for driving screws into tough materials.
Racing Drone: High-speed quadcopters and FPV drones that demand sudden, intense current spikes for acceleration.
High-Lumen Flashlights: Tactical flashlights and searchlights that need maximum brightness for short periods.
DIY Battery Packs: Custom packs for robotics, e-skateboards, and portable power tools. The Nickel Tab option is perfect for solder-free assembly.
Q: Can I use this in my cordless impact wrench?
A: Absolutely. The 20A output is ideal for tools that need short bursts of high power, like impact wrenches and drills. It will handle heavy loads without overheating.
Q: What's the difference between the three terminal options?
A: Flat Top – standard for most modern devices. Button Top – for older spring-loaded holders. Nickel Tab – pre-welded strips for solder-free DIY pack assembly.
Q: Is this battery protected?
A: No, it is an unprotected cell. Your device or BMS must provide protection against overcharge, over-discharge, and short circuits.
Q: What charger should I use?
A: Use an intelligent Li-Ion charger designed for 3.7V/4.2V cells. Do not use NiMH chargers.
Q: How should I store these batteries?
A: Store at 40-60% charge in a cool, dry place away from direct sunlight and extreme temperatures.

Spot welded into a 5S pack for old Makita. 20P provides great power runs jigsaw strong. Capacity balance good after cycles. Recommend.
Used in a 5 inch freestyle quad. 20A burst handles aggressive throttle. Sags less than some 25A labeled cells. Weight is good. Will order more.
Bought 4 cells for my high-power flashlight. The 10C discharge is no joke — ran on turbo mode for 40 minutes and the cells only got slightly warm. Much better runtime than my old no-name cells. EVE is a reliable brand, internal resistance is consistent. Will buy again.
Using in Emisar D4V2 with high drain emitters. 20A allows turbo without step-down too fast. Only 2000mAh so carry spare. Perfect flat top.
Capacity came 1950-2000mAh IR 12m¦¸. Building a portable soldering iron battery. Perfect. Fast delivery.
