Molex 2mm Pitch Connectors

These 2mm pitch plugs and sockets are ideal for use in limited spaces. The 2 pin versions provide a very small but safe method of connecting and disconnecting LiPo and the 3, 4 and 5 pin versions can be used for balance connections where a JST-XH would take up too much space.

A plug is a male plastic shell with female crimp terminals and a socket is a female plastic shell with male crimp terminals.

Many single and 2S LiPo come fitted with a 2 pin plug. Unfortunately, there is no manufacturer consistency in the way that the negative and positive wires are inserted into the shell. The Micron convention is that negative is at position 1, as shown in the image of a socket at the right. All leads and LiPo supplied by Micron are wired this way - see Connector Wiring for details; please contact us if you need your LiPo or Molex 2mm leads wired with pin 1 positive.

Plugs/Sockets


Molex 2mm Plug With Crimps (5 pack)

A 5 pack of Molex 2mm pitch plug shells and crimp terminals (each packet contains 5 spare crimps for you to practice).


Molex 2mm Socket With Crimps (5 pack)

A 5 pack of Molex 2mm pitch socket shells and crimp terminals (each packet contains 5 spare crimps for you to practice).

Adapter Leads

All of these adapters use the Micron wiring convention (pin 1 is negative). Please contact us if you need an adapter lead with pin 1 connected to positive.


Molex 2mm 2 Pin Plug to UM Socket Adapter Lead

An adapter lead to allow single cell LiPo with 'UM' battery connector to be used with receivers or ESC that have a Molex 2mm 2 pin socket. The Molex plug is wired with the Micron convention of pin 1 negative.

£ 1.95

Molex 2mm 2 Pin Socket to UM Plug Adapter Lead

An adapter lead to allow single cell LiPo with a 2 pin Molex 2mm battery connector to be used on receivers with a 'UM' socket (e.g. the Spektrum AR6410), or to allow the LiPo to be charged with a 'UM' charger. The Molex socket is wired with the Micron convention of pin 1 negative.

£ 1.95

Molex 2mm 2 Pin Charge Lead (1S)

A 250mm 1S charge lead with a 2 pin Molex 2mm pitch socket at one end and a red/black 4mm plugs at the other end for connection to a chargers's positive/negative sockets. For use with 1S switch plates.

£ 2.25

Molex 2mm to JST-XH 250mm Charge Adapter Lead

A 250mm charge/balance adapter lead with a Molex 2mm pitch plug at one end and a JST-XH plug at the other end plus 200mm red/black bare end wires for connection to a charger's positive/negative sockets. The red/black wires may be snipped off if your charger uses only the JST-XH connector for charging and balancing. If your charger does require connection to the charge sockets, suitable 4mm plugs are available.

The adapter is designed for charge currents up to 2A.

The Molex 2mm connector is used for LiPo charging and balancing where space is tight and there would be insufficient space for a JST-XH. These connectors are used on the Model Rail Wiring Harnesses.

Switch Modules


Switch/Charge Module - 1S

A small on/off switch and charge socket module for model vehicle installation. The module comprises a micro slide switch, 2 pin 2mm pin space Molex charge connector and 1.8mm LED mounted on a 20mm x 10mm GRP plate. The wiring comprises a 2 pin Molex battery connector on a 30mm lead, 100mm red/black/brown/grey wires with bare ends for soldering onto your receiver and voltage booster positive, negative, L and LED2 pads. The LED2 positive wire (brown) has a series resistor for use on 3.3V (Deltang Rx 'P' output).

The Molex connectors are wired with pin 1 negative for compatability with Micron LiPo for model rail and pre-wired Molex leads.

Switch/Charge Module (3A Toggle Switch)

A small on/off switch and charge socket module for model vehicle installation. The 1S module is suitable for a single LiPo/LiIon cell or a multi-cell NiMH battery. The 2S, 3S and 4S modules are for multi-cell LiPo/LiIon batteries which require all cells to be connected to an external balancing charger.

The module comprises a miniature toggle switch, 2mm pin space Molex charge connector and 1.8mm LED mounted on a 25mm x 15mm GRP plate.

The wiring comprises:

  • a Molex 2mm, JST-XH or JST-RCY battery connector on a 50mm lead; the JST-RCY is suitable only for the 1S module
  • 150mm red/black/brown wires with bare ends for soldering onto your receiver pos/neg/LED2 pads or splicing onto the receiver lead-out wires. The LED positive wire (brown) has a series resistor for use on 3.3V (Deltang Rx 'P' output)
