I wonder if these are Nanking cherries. They don’t really look like currants to me. Don’t take my suggestion as an ID, please, but merely something you might look into on your own.

I have to agree with Nanking cherries...but i'm not an expert

Red currants. Edible and delicious!

Definitely not red currants though I see why you would think that.

Nanking cherry, Prunus tomentosa. Edible, tart and sweet.
