Efest IMR 18650 3000mAh 35A 3.7V High-Drain Rechargeable Lithium Battery

Product Specifications

Key Features

• High-Amp Pulse Discharge: Engineered specifically for power-intensive applications, capable of handling rapid pulse currents up to 35A and sustaining a solid continuous discharge rate of 20A.

• Inherently Safe IMR Chemistry: Built on a Lithium Manganese Oxide ($ext{Li-Mn}$) chemical base that provides excellent thermal stability, lower internal resistance, and safe operation under heavy loads without needing an absolute built-in PCB layer.

• Extended Dynamic Runtime: Features a high-capacity baseline of 3000mAh, optimizing runtime for power tools, robotics, and complex electronic configurations before requiring a recovery cycle.

• Unprotected Flat-Top Profile: Clean flat-top termination designed directly for tight, clean fits inside mechanical layouts or custom multi-cell series/parallel assembly packs (such as 2S to 5S configurations).

• Industrial Distinct Styling: Wrapped in a professional metallic purple anti-static sleeve with clearly printed manufacturing specs, batch warnings, and voltage baselines for fast identification.

Technical Specifications

Primary Applications

Optimized specifically to drive modular engineering setups, heavy hand-held equipment, and automated projects:

• Custom Battery Pack Assemblies: An exceptional option for designing multi-cell series setups (2S, 3S, 4S, 5S) with external BMS frameworks for robotics and portable electronic utility banks.

• High-Torque Cordless Power Tools: Powers heavy-duty field maintenance tools, diagnostic line meters, cordless drivers, and electronic testing benches.

• Extreme-Lumen Tactical Searchlights: Delivers uninterrupted high-current power for premium searchlights, portable job site lanterns, and heavy security illumination arrays.

• High-Performance RC Engineering: Supplies strong, reliable current bursts to performance-grade remote vehicles, commercial drones, and mechanical prototypes.

Critical Handling Guidelines

Safety Warning: This is an unprotected industrial cell. Never drop loose cells into a toolbox, drawer, or pocket where they can shift against metal objects (screwdrivers, keys, or screws) and cause a short-circuit. Always store the cell in an insulated plastic case when not in active use. Charge exclusively inside a dedicated external smart lithium-ion charger with integrated automatic voltage cutoff.
