1. Fast melting speed, good solder diffusion, forming strong, highly conductive, and neat solder joints.
2. Solder wire specifically designed for small battery panels, no soldering machine required.
3. High activity, low melting point, and fast soldering speed.
4. High insulation resistance, good conductivity, strong and durable.
5. For soldering small metal plates, nickel sheets, cell terminals, and flexible battery connectors for battery BMS.
