Acabo de ver esto en la pagina de antelife.
We will send a C2 battery for free to our customer who buy it and only get one battery, if you receive one, pls contact our service as soon as possible, we will send out at May 30th together, and will do not send after May 30th.
Por lo que entiendo a quien le falte la segunda bateria tiene que reclamarla, las mandaran todas el 30 de mayo y despues no mandaran mas.
