it depends on the manufacuters rating of the connector.
some have a per pin current rating and others have a combined rating, yo see this a lot in the "oriental markets" to boost their ratings.
i think 10A sustained in that cheap 4 pin connector is pushing it. it will get hot and in due time it will melt.
try using something like this: https://www.aliexpress.com/item/WEIPU-W ... 82457.html
i use these connectors for a lot of setups. the panel side has a spring loaded cover so crap can never get in and you cant forget to close it.
it also has no problem with 15A sustained.
