Micro RC LiPo Connectors (1-10Amps)

Molex Connector:

This small Molex RC battery connector type is also known as JST PH 2 pin and their ratings are 1 and 2 Amps. These connectors are little and also having low cost. You have to handle it carefully because it can easily loosen up while soldering wires to the female connector.

It cannot take too much heat for a long time. You can use thick CA glue to avoid loosening up of pins. The thin CA glue cannot be recommended because it can move further and can insulate the connector. Male Pico blade connectors with attached wires are more suitable than the connector without expensive crimp tool. You can handle male connector pins easily because they are crimped on to the wires and this is the reason there is no effect of soldering heat on it.

Advantages:

• It is very helpful to assemble two different components
• It provides ease in repair because it is easily replaced
• It gives design flexibility
• Upgrades are easy

Applications:

• These little connectors can be used on Blade and Walker micro helicopters that are small as well as single cell LiPo RC aircraft.

Deans Mini Connectors:

This solid little RC connector battery type value can range from 7 Amps up to 12 Amps. If you want to push it more than 15 Amps value is enough for it. Always take care of overheating the pin because it can cause damage.

They are very comfortable to handle and you can easily solder wires without any issue. They are “non-sex-specific” and it means that there is no need to get a different plug for both male and female. It needs only one plug for both of them. This is the reason it is very easy to plug and unplug for users in this RC battery connector type.

All the solder joint that is exposed need heat shrink for insulation purpose. To avoid shorting hazard you need to take care that exposed pin is not “+” on the source side.

Advantages:

• They are more efficient than any other connector.
• These connectors offer the resistance-free connection for MOSFET or battery.

Applications:

• These connectors you can see for RC circles and now you can see them also for Airsoft.

 

Servo Plugs Connectors:

These servo plugs connectors are the other one of the best RC battery connector types. These plugs can take around 3 Amps load but if you want to increase the load then it can be up to 6 Amps. But its duration should be short. It is a very good option to make your own servo connectors. Your positive efforts can save your money to spend on it.

You will find three pins in servo connectors and when you use them as power plug then only two pins get in use. You will use the middle “+” pin and “-“outer ground pin only. The other outer signal pin will leave untouched. This is the reason when you will see only two wires in red and black color in servo connectors when you use them for the power plug.

Advantages:

• The servo plug connector can work with any servo controller, the brand of receiver, and servo extension.
• You can make your own servo connector.

Applications:
