Key Benefits

High Energy Density Design: Utilizing advanced stacked lamination technology and high-performance cell materials, achieving energy density of 180Wh/kg. Compared to traditional lithium-ion batteries, runtime can increase by 20-30% in the same volume—particularly valuable for smart wearable devices with strict endurance requirements.

Extended Cycle Life: After 500 standard charge/discharge cycles, capacity retention remains ≥80%. Under normal usage conditions, the battery can last 2-3 years without replacement. For B2B customers, this significantly reduces after-sales maintenance costs and user complaints.

Complete OEM Customization: Supporting multi-dimensional customization including capacity, dimensions, voltage platform, protection board solutions, wire specifications, and packaging. From prototype development to mass production, full technical support with fastest 15-day delivery to meet rapid time-to-market needs.
