3.5mm Bullet Connector Pair, Male-Female, for ESC and Motor Wiring

Bullet connectors are the standard way most brushless motors and ESCs terminate their three power phase wires in the RC and drone hobby, using a simple round pin-and-socket design that connects and disconnects quickly without needing to solder a permanent joint every time a motor or ESC gets swapped. This 3.5mm size is one of the most common bullet connector sizes used across small to mid-size multirotor builds, frequently showing up pre-installed on 250mm-class FPV racing quad power distribution boards and matching ESC/motor combos designed around that connector standard.

Each pair includes one male and one female connector, the two halves needed to terminate both ends of a motor-to-ESC phase wire connection. Like the XT60 and other bullet-style connectors common in the hobby, these ship unterminated with bare solder tabs, letting a builder solder the connector directly onto whatever wire gauge matches the specific motor or ESC's current rating, rather than being locked into a fixed pre-made cable length or gauge.

Because bullet connectors (unlike the keyed XT60) are typically not polarity-locked by their physical shape, builders working with these connectors on motor phase wires benefit from the fact that motor direction can actually be reversed simply by swapping which two of the three phase connectors are matched up - a detail worth knowing when wiring a new motor and needing to correct its spin direction without re-soldering.

Builders assembling a new FPV racing quad power distribution board, replacing a damaged motor or ESC connector, or needing matching bullet connectors for a 250mm-class multicopter build will find this 3.5mm pair a direct match for the connector standard already used across much of that segment of the hobby.
