This topic has to do about presenting the few information’s available regarding the actual connector plug, which many latest generation of chargers are using.
 
All Hyperion chargers and many other top dollar solutions, they have a slot over the charger body for connecting a temperature sensor.
And especially EOS 0720i Super DUO3 has two such inputs due it design as 2 x 500W chargers in a single case.

I did purchase one original Hyperion temperature probe so to have it as comparison point, because under the hood there is a usual LM35 sensor and just three cables.
In my application I will need a custom length of the sensor cable and possibly two of those.

When started researching of which is the actual name or part number?  of this specific connector, very shortly I got in to a dead end.

Visually this connector looks similar to DuPont connector 3-pin but is not the proper one.
This temperature sensor needs 5VDC to operate and proper polarity is important.   
After lots of research discovered that this connector is known to RC hobbyists by the name of Futaba J or even as Futaba servo connector.
Futaba has actually many connectors for special use and there is no default type of Futaba servo connector.

What seems crazy is the pricing when seeking this plug alone as futaba product.
When at about 3$ USD is available a third-party sensor with LM35 plus plastic case with wires and this plug too.

Therefore I do recommend as wiser move, getting a second OEM complete sensor than just the connector.  ;)

By this message I wish to pass a warning.
In my sensor the person who did the soldering of wires over the LM35 he did not follow the color code.
I had to open up the sensor so to find out which wire is soldered to its leg of LM35.
It was much easier for me to just rearrange the pins in this connector so my LM35 sensor to start operating.
