Replacement battery holder

Hi, I have been having difficulties with my project and have narrowed it down to a faulty battery holder. Would it be possible to get a replacement battery holder (for the PiCar 4WD - 2x 18650)?

Do you have any problems with your battery holder? We suggest that you provide us with a video of the problem so that we can analyze and solve it.
If there is a problem with our battery that causes your robot to not work properly, we will arrange for a new battery holder to be sent to you.
