Just spent a long time on the JST site and the Molex site trying to identify the following connector. It's got 2mm pitch and is used for a battery connector in a small RC quadcopter.

I found them on AliExpress listed as "MX 2mm" at https://www.aliexpress.com/item/4000639410772.html. MX = Molex?

This UK site here http://www.micronradiocontrol.co.uk/conn_molex2mm.html simple named them "Molex 2mm".

Yet, I scrolled through the entire Molex 2mm pitch catalogue but none was even close.

After I posted the Q I came across https://connectorbook.com/identification.html. It helped me identify this as Molex (indeed) 51006 + 51005.
