Company Profile

Product overview

Our Dynamic Power 3.7V 6000mAh Lithium Battery Replacement—a tailor-made premium power solution exclusively crafted for the JBL Link20 Bluetooth Speaker, designed to tackle the key pain points that plague users of generic replacements: erratic power delivery that distorts audio, insufficient capacity for all-day use, and ill-fitting designs that compromise the speaker’s portability.

Unlike one-size-fits-all batteries that force JBL Link20 to adapt to subpar power, this replacement is engineered in reverse—built to match the speaker’s original power architecture down to the smallest detail.

At its core lies a smart dynamic power management chip, which adjusts current flow in real time to align with the speaker’s audio demands: whether you’re streaming soft jazz for focus or cranking up upbeat anthems for a picnic, it delivers consistent, stable power that preserves JBL Link20’s signature balanced sound—no volume dips, no distortion, just pure, crisp audio.

Competitive Advantages

I.Improved Battery Life

Compared with the original battery, the Dynamic Power 3.7V 6000mAh lithium battery has a higher capacity. Under the same usage conditions, it can provide longer power support for the JBL Link20 Bluetooth speaker, significantly extending the speaker's battery life and reducing the number of charging times, making your usage more convenient.

II.Maintained Portability

Although the battery capacity has increased, this battery adopts a compact and lightweight design. Its size precisely matches that of the original battery, and its weight is relatively light. After being installed in the speaker, it does not significantly increase the overall weight and volume of the JBL Link20, maintaining its original portability and allowing you to carry it with you anytime and anywhere.

III.Stable Power Supply

The battery has stable electrical performance and can provide a continuous and stable current and voltage to the speaker. During music playback, problems such as sound distortion and intermittent sound caused by voltage fluctuations will not occur, ensuring that the speaker always works in the best condition and providing you with a high-quality audio experience.I

V.Safe and Reliable

The Dynamic Power battery integrates multiple safety protection mechanisms, such as overcharge protection, over-discharge protection, short-circuit protection, and overcurrent protection. These protection mechanisms can effectively prevent dangerous situations such as overheating, fire, and explosion during battery use, ensuring your personal safety and the normal operation of the speaker.
