Yes, pretty much the same applies as the Bela Mini, described here: https://learn.bela.io/using-bela/bela-techniques/powering-bela/, so you can use a 5V battery plugged into the USB port or P1.01 SYS.VIN. Alternatively you can use a LiPo into P2.14 SYS.VBAT.
One advantage over the Mini is that now there's a solder bridge to use 3.3V as the voltage reference for the ADC, so that you can still use the analog inputs even when running on battery.
