What Are the Different Types of RC Battery Connectors?

Li-ion battery has become one of the mainstream energy sources for drones, remotely operated vehicles and other remotely controlled devices. And RC lithium polymer battery connectors are one of the key components that connect these batteries to the devices. In this article, we’ll explore several common types of RC lithium polymer battery connectors, as well as their benefits and applications.

RC Battery Connectors

The discharge connector and the balance connector are the two primary connectors found in LiPo batteries. The device’s power supply is handled via the discharge connector. The precise type of discharge connector may differ, but it is intended to withstand the device’s current requirements. A few examples of common discharge connectors are Molex Connector (JST PH 2 Pin), Servo Plug Connectors, XT30 Connectors, XT60 Connectors, TRX Connectors, EC5 Connectors, XT90 Connectors and others. One secondary connector used to balance each of the LiPo battery’s separate cells is called the balance connector. LiPo batteries are made up of several cells connected in series, and in order to get the most out of the battery and extend its life, it is essential to make sure that each cell is charged and discharged equally. The balance connector, which is used to monitor and balance the voltage across the battery’s cells while charging, usually consists of many wires, one for each cell.

LiPo Battery Connector Types

Molex Connectors (JST PH 2 Pin)

Micro RC Lithium Polymer Battery Connectors (1-10 amp) rated at 1 amp and 2 amp must be handled with care as it can easily come loose when soldering wires to the female connector. It must not absorb too much heat for long periods of time. Thick CA adhesive is recommended to avoid pin loosening.

Advantages:

  • Very useful for assembling two different components
  • Easy to maintain, easy to replace
  • Flexibility in design, upgrading is easy

Application:

  • These small connectors can be used on Blade and Walker micro helicopters, small and single cell lithium polymer batteries for RC model airplanes.
  • It is used to power motherboards, fans, disk drives, video cards and CD/DVD drives.

Servo Plug Connectors

One of the best types of RC battery connectors. These plugs can handle loads of about 3 amps up to 6 amps. However, the duration is shorter. There are three pins and when used as a power plug, only the center “+” pin and the ” -” external ground pin are used. The other external signal pin will remain unchanged.

Advantages:

  • Servo plug connectors can be used with any servo controller, receiver brand and servo extension.
  • You can make your own servo connectors.

Application:

  • It is used for RC powered methods, including aileronless systems and receivers.
  • It is used for PV terminals, but you cannot use them for LiPolymer battery connectors.
  • Small RC Lithium Polymer Battery Connector (10-30Amps)

XT30 Connectors

The connector can withstand a 30 amp load, which you can increase to 40 amps. Heat shrink is required to insulate them, and because of the nylon material, you don’t have to worry about overheating or loose pins when soldering wires.

Advantages:

  • They provide a better contact surface so they can handle larger amplifiers.
  • They also have lower drag.
  • Small size and light weight.

Application:

  • It’s perfect for 35A+ applications.
  • Used for small drones.

XT60 Connectors

These are better than deans or EC3 connectors because they can be easily plugged and unplugged. Since it is also made of nylon, it does not have the problem of melting or loosening easily. The lithium polymer batteries produced by Enerforce, which are mated to the xt60 connectors, are able to withstand long periods of use.

Advantages:

  • Ensures high Amp connectors
  • Super strong and can avoid melting or deformation.

Application:

  • The XT60 is best suited for applications above 65A.
  • This helps to connect the RC fpv drone to Robotics Electronics perfectly and to the battery perfectly. Like the Ovonic 2200mah 3s battery for example.

EC3 Connectors

EC3 connector can handle loads of about 60 amps and use a 3mm header. They are relatively expensive and are not easily plugged or unplugged compared to other connectors.

Advantages:

  • EC3 creates a very secure connection that is very difficult to disconnect.
  • They don’t melt and don’t require heat shrinkage for insulation.

Application:

  • EFlite
  • Blade Helicopter

TRX Connectors

This RC battery connector type can be used on Traxxas RC boats and vehicles. But you can also use it for other applications in the current 60 amp range.

Advantages:

  • They can be easily inserted or pulled out.
  • They do not require heat shrinkage to keep them warm.
  • Low resistance can be maintained.
  • Reverse polarity protection prevents backward insertion.

Application:

  • High density and high discharge battery pack.
  • Brushless motor.

EC5 Connectors

In addition to using 5mm bullet pins, this type of RC battery connector is larger than the EC3 connector. Because there is a larger surface area for each given touch, they are superior. They have a 120 amp maximum load capacity and a 150 amp maximum burst. These are ideal for use with large-scale electric planes and electric heels that range in size from 700 to 800.

Advantages:

  • Both connecting and disconnecting these connectors is simple.
  • Soldering is quite simple.
  • High amps are rated for this connector.

Application:

  • When it comes to electric hail, they are ideal for usage with sizes 700–800.
  • Batteries for RC cars and large-scale electric planes are also made with them.

XT90 Connectors

This connector has a 90 amp maximum load capacity and a 120 to 130 amp maximum burst limit. This connector is easier to plug in and unplug than the EC5 connector, if you compare the two.

Advantages:

  • The close fit connection made by the XT90 results in less resistance.
  • Offers Sturdy and Dependable Connection

Application:

  • RC chargers, RC ESCs, and RC UAV lipo batteries (XT90 Female) are among the RC models that employ these connectors (XT90 male).
  • Additionally, remote-control airplanes employ them.
