The pins are to connect the temperature sensor which uses a standard servo plug. The wires to the battery are permanently soldered to the LiPo monitor - you add your own plug normally.
For the price they are a good buy. Handy to use as an add-on temp alarm when you are charging if the charger does not have a probe of its own.
