The Rock64 doesn't really have on-board battery support; this is just one of the reasons the Rock64 is not really suitable for notebook application.
You may provide battery support yourself of course; use a 12v SLA battery with a dc-dc converter with low-pass filter (PI filter) and then monitor the 12v input with ADC utilizing either I2C or SPI (good ADCs are available in both versions).
