1) Would it be possible to have two different types of batteries with Bluesolar DUO? For example 12V LiFePO4 and 12V AGM battery or then two AGM batteries with different sizes.
2) Also is there any output for battery cut-off at low voltage on Bluesolar DUO? Of course I want to keep my batteries without getting to too low voltage... Even a separate relay would be ok, but I would not like to build the logic for that (Battery Protect device is too expensive also).
3) How about two batteries of same type & capacity (Li, AGM or so), but having one completely empty and other one full. Example: You connect the full or empty battery on bank 2, while the othe one in bank 1 is in different state, what happens?
