I haven’t found much useful information on what the applications or reasons would be for a three output charger.
Consequently I have 12v AGM
Why wouldn’t one just run a combination of parallel and series to charge their battery Bank? Is there a limit per bank and this triples it? Is it for the option of having One Bank of agms and One Bank of lithium for example?
What are the different benefits or potential uses or limitations of the three output feature on the charger?
The three outputs are non-isolated, so must share a common negative return path, and all outputs follow the single programmed charge profile, so it would not be generally recommended to connect battery banks with differing chemistries to the outputs. In that case, it is better to use separate chargers for each chemistry being charged.
