Bien pues cómo a caaaasi todos los foreros a mí ya me han respondido ésto sobre las baterías:
"Hello my friend,
Please do not worry , we will resend one battery to you , but it will be sent in a certain time ,
We will send it to all customers who receives one battery (it is clear to written in our website , please confirm it ) .
As zopo factory only give one battery , the extra one need purchase by ourselves .
While the c2 is widely out of stock , factor are busy producing it , so please wait patiently .
Best Regards"
A esperar pues que me envien la segunda.
