2019 radrover here, but same spec battery, I think. No, "red hot" is not normal. I've never had anything beyond slightly warm. Shouldn't matter, but is the battery key switch in the "off" position? Also, if you're charging in europe, does the charger need to have a switch changed for 220 input voltage?
ETA: I'm charging in US on 110V. Just checked, the back of the charger says it's good for 110-240 input voltage.

Red Hot means is "glowing" red hot, some hyperbole I think in this case. Is the plastic on the charger melting?
Hold a 100 watt incandescent bulb in the palm your hand. It's hot .
If it's a dual voltage charger the amount of heat will be the same.

Except, by description, it is not. I would never describe my charger's temperature as "red hot", or even as too hot to hold in one's hand.
@Graysco242 You wouldn't happen to be charging the bike with the charger hanging mostly in mid-air, with only one end touching ground? Coincidentally, I am doing that right now, and 2 hours into the charge the charger is quite warm to the touch. Not too hot to hold it, but definitely warmer than I've ever felt before. Usually I have the charger flat on the floor (wood or stone floor). You could also position the charger so it has lots of contact with the aluminum frame of the bike; lots of heat sink available there.

I don’t like that the charger gets so hot either, so I use a small usb powered fan to blow cool air on it:
