Please note we are not manufacturer of these lithium batteries, they are from China top brands like Narada,TopBand,PylonTech,ZTT, Shoto, ScaredSun,GBS etc. But we only choose the batteries from big brands with top level quality. 

For some reasons, the sales channel of the China big brands are not yet very good so we have to source from speical China domestic channels to get best prices at same batteries, same qualities.

We suggest you please also check with their agent in your region and then compare and choose, thanks!
