Latest revision of my molex adapter that will convert onewheels power 16pin molex connector into 2 XT60, 1 XT30, 1 8pin JSTJWPF. Also the gasket is bigger so it covers more area. It is good but i still recommend using some silicone to be sure.
Version with one XT60 is also available.

Screw (M2-6) holds the connector from going inside the box but it will go outside when dissconecting. Fix that with epoxy or hotglue.

Adapter is secured with M5-20 screws.

Gasket - TPU
Adapter - PLA / ASA
