I think I understand better now.
You mean something like an "extended" battery or a larger capacity battery that will act as one big battery in the AK120.
Short of opening the AK120 case and making a bigger case with a bigger internal battery, I don't know who that would be possible.
The only way to charge/power the AK120 is through the usb port (without opening the case). So from a performance/functionality standpoint, any external battery would have to connect via the USB port and work the same way.
I can see that charging both the AK120 and an external battery pack is not as convenient, but that's the only way I can think of to have longer battery life.
