Good manufacturers will install a heater on the battery that will keep it warm while charging. Also it sounds like the cybercuck is using over 20 amps for something else if they have a dedicated 50amp charger. So either the battery heater is using more energy than they can provide or the thing is broken.

My money is on being broken.
The guy posted a follow up comment. The charging connector was broken.
