Could use some help with my setup!

Thanks for taking the time to read this;

I’ve got a simple setup, 18650 battery with a driver (cree XRE-Q5/XPE XP-E/XBD XB-D driver 17mm 20mm DC3-4.2V 700MA)
and LED (CREE XPE XP-E w-3 w 3535 SMD High Power LED Emitter Diode)

Works fine, untill I fully charge the battery and then the LED gets so hot it melts the solder.

I don’t get it, it’s the right driver for the LED?

Measure the current, that goes through the LED. If it is too high, your driver might be broken
