1. STANDARD MATERIAL PROVIDES BETTER PERFORMANCE These JST cable wire connectors are made of quality materials to ensure durability and performance. The wire core is constructed from tinned copper, offering electrical conductivity, efficient heat dissipation, as well as strong oxidation resistance and weldability. 2. MULTIFUNCTIONAL 2P / 3P JST CONNECTORS This set includes two types of connectors, widely applicable in daily use. These JST rightangle female plug wires are primarily designed for circuit boards. The 2pin and 3pin plugs are suitable for mini RC helicopters, indoor 3D models, LED light bars, LiPo batteries, ESC BEC boards, NiMH batteries, household appliances, lighting, industrial equipment, electric heating connections, and more. 3. SAFE TO USE These electrical cable wire connectors feature an insulated design for secure operation. The wire's insulating layer is resistant to peeling, while the tinned copper wire ensures rapid heat dissipation, enabling and stable performance. 4. QUALITY PRODUCT The package includes 20 JST connectors—a mix of 2pin and 3pin plugs—providing versatility for various projects. Use them to connect multiple circuit boards or old connectors with ease, thanks to their reliable design.
