Definitely.? Most power supplies take a very dim (as in permanently off) view of reverse voltage applied to their terminals.? Most also don't like to be tied to another power supply in parallel unless designed for it.
If you're going to charge a battery with a Chinese (or many other types) power supply, put a series diode in so that the supply can't be fed by the battery.

Be sure to add an external reverse protection diode across each output, in case there isn't one built in.
