Noone Can Find An Original Battery In Eu

[kamakasnh]

We (the EU citizens) have support Xiaomi market by buying Xiaomi Brand phones, but we have a problem. When it comes the time to buy a second battery, there is no market with authentic (original) xiaomi batteries. I bought from i....ou.com an original BM30 for my Mi2S the same date with my phone purchase, and after that i am unable to find sth like that. BM30 and 20 has extinct from this site. And sites like aliexpress and ebay are selling only cheap replacements. I bought Redmi Note 2 and I cannot find a second battery even though the phone is in market few months. There are a storm of fake ones which is unable to backup you with energy. Please INFORM the China Market if you have connections to supply with batteries the online market.
Does anyone have suggestions about a Xiaomi original Battery after sale market?
