I've never repaired a battery before but I don't think there is anything you can do that doesn't involve opening it up. It's probably the BMS that is causing the problem. If you wanted to check the battery, you'd have to open it up and take a volt meter and measure all the cells. The cells should all be above 2.5v if it's a lifepo4. And above 3.0v (I think) if it's LIPO. Your new battery should be fine if it was checked out by ebikes.ca and he said it would work.
If you had a 250 w bike before, you'll love this one that you are getting with a 48v battery. It'll probably go about 28 mph.
