Our advantages

Chinese manufacturing processes have undergone years of iteration, resulting in mature and reliable technologies. Many international corporations opt for production outsourcing in China.  As an electronic components manufacturer in China, our products can fully replace those of major international brands in 99% of applications without the need for testing verification. Our products boast high consistency in quality, reasonable pricing, ample inventory, flexible supply, short lead times, and professional after-sales service. 

Description

The SL2112 series is equipped with a high-precision voltage detection circuit and delay circuit.By monitoring the battery's voltage and current, it provides protection against overcharging, over-discharging, over-current, and short circuits. It is suitable for protection circuits of single lithium-ion/lithium polymer rechargeable batteries.
