No. Batteries have shipping issues in terms of regulations and need special arrangements (which also increases the cost) so we recommend you buy a battery locally or you can keep the USB plugged in. The maximum battery size should be 62 x 35 x 5 mm. You can check more about battery specs in the battery section in docs here. 

The battery is fitted inside the enclosure, behind the e-paper display screen.
