you can buy a cowon q5w battery like the original .
go to alibaba.com and looking for 6500mah 3.7v batterie . i have buy 6 battery´s for 6 $ .
i had buy from XTY batteries ( in shen Shzen )
With original PBC controller ( any PBC will work ) and with the original connector ( i don´t know the name of the connector - but the seller is very good and he will help you . i had a nice woman he had help me . ( kelly from XTY )
you can build your own battery´s with any size .
