Hi!
I have same problem. And at least here in Germany it seems to be impossible to get original battery. I already ordered two different ones and both came without the charging and heat control…
@boonsong: how can I change the small battery controller board from one battery to another? Do I have to desolder the contacts on the back? And then solder it to the new battery? Or how are they attached? I don’t want to destroy everything…
thx in advance
Chris
