i'm thinking a better solution would be to set up battery/charging as a service to the rock64 rather than trying to internalize both battery/charging . you could probably use one of the smaller microprocessors like pro mini or esp32. have it monitor the battery charge status and keep it fully charged. or go solar as marcus mentioned. the problem would be that the rock64 can need upwards of 3 amps current depending on what it is doing at any given moment. that would need a sizable battery. and difficult for solar recharging capacity. depending on how mobile you need the setup to be a small ups might be a good solution.
