As you can see from the other post here, you can add any wireless battery cam to Homebase2.
However, none of Eufy’s cams are designed for battery replacement. If you control your charging cycles to avoid overcharging or charge depletion, your batteries should last for over 100 cycles, so they would probably outlast you. I charge mine when they get to 50% and charge to 85-90%. Also, avoid charging when temps are below 40 deg F., as the electrolyte turns solid at that temp.
