Dongmagnetic 18650 Power Battery 4000mAh 10C High Discharge Lithium Cell

This Dongmagnetic 18650 battery is engineered for high-magnification applications, delivering a strong 10C discharge current alongside a generous 4000mAh capacity. Whether you need reliable power for RC vehicles, power tools, or portable electronics, this nickel cobalt manganese (NCM) ternary lithium cell is built to meet the demands of high-current devices. With multiple built-in protections, it offers a safer power solution without compromising on performance. Each battery is specified at a nominal voltage of 3.7V and a capacity of 4Ah, making it a practical choice for enthusiasts and professionals alike.

Features and Construction

This cell combines a protective circuit system with a proven lithium chemistry to support both safety and performance in high-drain roles.

Material and Build

The battery uses nickel cobalt manganese ternary lithium (NCM) chemistry, which provides a stable energy density and high discharge capability. A metal casing houses the cell, and an integrated explosion-proof valve adds a layer of safety. The unit includes overcharge, overdischarge, and short circuit protection to help prevent common electrical faults.

Size and Practical Fit

Built in the standard 18650 form factor (18mm diameter, 65mm length), this battery fits many devices and battery holders designed for cylindrical lithium-ion cells. The flat-top design suits soldered or spot-welded connections for custom battery packs.

Uses and Placement

Designed for high-current applications, this battery is ideal for scenarios where a standard 18650 cell would be insufficient.

RC and Hobbyist Use

The 10C discharge rating makes this cell a strong candidate for radio-controlled cars, drones, and planes that require bursts of high current. The 4000mAh capacity also supports longer run times between charges.

Power Tool Applications

Cordless power tools such as drills, screwdrivers, and small saws benefit from the high current output and built-in protections. The battery can be integrated into custom packs or used in compatible single-cell tools.

Benefits and Buying Value

This battery offers practical advantages for anyone who needs high performance from a standard-sized lithium cell.

Reuse and Low Maintenance

As a rechargeable lithium-ion battery, it can be reused hundreds of times with proper care. The integrated protection circuit helps extend service life by preventing overcharging and deep discharging.

Why Choose This Product

With a 10C discharge rate and 4000mAh capacity in a widespread 18650 form factor, this battery fills a specific need for high-drain applications. The inclusion of multiple protections and an explosion-proof valve adds peace of mind compared to unprotected cells.
