Can't see the pictured Y-cable on his website and, in any case, their cables are somewhat pricey.
You should contact Elijah Audio.

Do you know any cheaper ones anywhere and also what battery/ battery casing is that in the picture? Thanks
Sorry, I don't know if there is another provider of such a USB OTG-Y cable (i.e. "Elijah Audio USB OTG-Y cable").
There are different types of USB OTG-Y cable:
. "Elijah Audio USB OTG-Y cable": no Voltage bus (Vbus) power line from Android device (i.e. USB host)
. USB OTG/ACA-Y cable:

A USB OTG device is configured to USB host mode supplying or drawing power, or USB peripheral mode by ACA/OTG software/hardware measuring the value of the ID resistance "R" of the USB interface.
According to the value of the ID resistance "R":
. the Android device should act as a USB host, interwork with the USB DAC acting as a USB peripheral, and draw power from an external battery or another external power supply.
". the Android device should act as a USB host, interwork with the USB DAC acting as a USB peripheral, and supply power to the bus-powered USB DAC
. the Android device should act as a USB peripheral, interwork with a USB host, and draw power from an external power source
. the Android device should act as a standalone USB peripheral, and draw power from an external battery."
