I inquiry the quotation of SEM to several company in the forenoon. I received a phone call from a Japanese Shanghai agent in the afternoon. He said 300000 times SEM is about us$100000 and the 500000 times SEM is more than 200000, the best brand is HITACHI (S4700:500000). I ask him to send an email to me.

I study Lipo battery from the web of Evbbs.com. I got a state standard of “Lithium batteries for electric vehicles”. I shared it with our colleagues through uploading to our QQ group.
