Dear @joe and @IAP,
I have the same problem.
Filed it under support #35434 just now, incl. photos of the problem.
Very unpleasant and disappointing to see such manufacturing issues.
Please help to push the support team to do something about it.
As I am located in China (the miraculous country of origin of our beloved FP) and would like to avoid unnecessary shipping costs, delays and CO2 footprints, I would be happy if someone from design & production department could advise the Changhong Battery model no. which is equivalent to the F1B101, as it may be easily available here in China from online stores at Taobao:
It’s no secret that FP is based on an existing Changhong design, just which model, and to which extent they are compatible is not clear.
