Just noticed this today after a flight. Left the battery in the hex for about an hour after flight. Is it of any concern, must have got a bit hot at the connection

There have been issues related to either inadequate contact design on the first version of the H520e battery, or weakened/broken contact blades on the original Typhoon H/HPlus/H3/H520 battery Deans type contacts.
Either way, the battery should be discarded and the drone contacts inspected.

Here are a few of the many related threads:
possible battery issue when using e30zx camera.
battery meltdown round 2
H520e power loss at low altitude
Catastrophic GiFi Battery Failure and Loss of Aircraft

Cheers for reply, it was a h plus and matching battery. Might need to open up the drone to make sure all good on that end

Moved thread to the "HPlus Discussion" section.

Check the spring portion of the Dean’s connector on both contacts inside the H+ and on the battery.

This is what they look like on the male portion of the connector.

You can check the ones on the female portion with a small thin flat blade screwdriver.

The connector on the inside looks nice and clean with spring attached. I may need to open the hex to get a closer look but from what I can see there is nothing melted . Is there meant to be a spring on the battery side? I have a main board from a h480 and there doesn’t appear to be anything to special on that end that could go wrong, maybe a spring could break , hopefully didn’t get hot enough to melt the solder, pretty doubtful

A bit out of focus, but those seem to be fine. I’ll check the female connectors in one of my batteries in the morning just to double check myself, but I seem to recall that they also have a spring.

Whatever happened, it got hot. I don't know how hot, but the effects of the heat on the drone side spring could be an issue. It will come down to comparing the condition of the potentially heat weakened spring to a known good spring. Or swapping the connector out for one that has not had a bad day.

That picture was off a h480 board I have. I was just seeing was there much that could go wrong on that end but the one inside the h plus also looks good, hard to tell unless the shell is opened

Ahh I didn’t even consider this but u are correct, the heat would definitely have effected the spring on the hex itself
