Performance Battery
Dual Battery Privilege

Since the GS 8440 pre-order launch, we have received many genuine feedbacks, positive reviews, and suggestions from our users. Based on the needs of different riding scenarios—especially the demand from hardcore riders for high-rate discharge performance—we officially present the Performance Edition battery equipped with Samsung 50S high-rate cells (84V 40Ah), built specifically for the GS 8440.

For early customers who have already pre-ordered and received the GS 8440 Standard Edition, we are offering a one-time personalized configuration price of $599. Your original Standard Edition battery (equipped with Samsung 50GB cells) stays with you—no need to send it back.

The Performance Edition battery is an optional personalized configuration, not a requirement. The Standard Edition itself delivers powerful performance and well-rounded capability, sufficient for the vast majority of riding conditions and needs. Whether you choose to add it or not, we respect and appreciate your choice.

We devote all our energy to product optimization and serving our real customers, continuously refining our products and systems, honoring our warranty commitments, and giving back to every bit of trust through action. We do not engage in meaningless online arguments; we focus on making our products and services better.
