Specifically the blue input port. I will be connecting these batteries to to a charger/inverter with the hope of adding solar soon. Of course there is no documentation so my question is the blue port a charging port or an information port? Should I use it with the charger or just connect it via the positive/Negative lugs? When I add solar should I connect the CC via this port? Thanks for the help.
