The Jeti Model AFC connectors eliminate the flashes often witnessed when connecting controllers and battery packs. Available in 4mm, 5.5mm and 8mm variants the female plug sports a SMD resistor that does away with the usual flashed that occur during connection and that can harm the surface of both the male and female plug. The sets contain two male connectors, a usual female and an AFC female connector together with red and black shrink wrap.
Replace your existing connectors or install inline between your existing connector and speed controller for eliminating connecting flash spark.
