Is the recharge threshold and terminal battery voltage adjustable? I want to keep the batteries between 80% and 20%

No. I don't think this is possible, unlesss you write a script that monitors the voltage or % of charge, and open a relay that would cut off the power input to the system... You would need some external equipment (arduino?) for that.

Are the batteries hot-swappable? In other words, can I connect an external power supply and swap the batteries out while that is on?

Hi friend, Sorry that the X728 on board 18650 batteries does not support hot-swappable, please swap the batteries after power cut off. best regards, Geekworm Team

Does the rtc have a separate battery? or does it run on the 18650 batteries? what happens if you remove them? will it "lose" time?

Hi friend, The RTC function runs on the 18650 batteries. It will "lose" time if you remove the 18650 batteries. best regards, Geekworm Team

Can I use more than two batteries with the x728?

It holds two batteries, it does have an second input for more battery boards.
