Small polymer lithium batteries are mainly used in 3C digital fields such as smart bracelets, smart glasses, smart rings, and TWS true wireless Bluetooth headsets. It has the characteristics of small size, large capacity, high high and low temperature discharge performance. The 3.8V high voltage system is our independent development system, which provides more sufficient capacity for small space bracelets and Bluetooth products to achieve longer battery life. Warmly welcome friends in the industry to visit and guide!
