Just got one but the terminals are tiny like 14 gauge.
I get that it is supposed to be able to charge two batteries at once, would have been nice if they disclosed that tidbit since I am already charging multiple batteries at once!

Dual Port "Charge Controller" ?
A solar charge controller with 2 DC Outputs ?
Or a Charger System that can charge 2 batteries at once ?
Provide a link to the product / device.
I charge 6 Battery Packs (280AH ea) at once with a total of 1680AH set in parallel. My BMS' do limit the max Amps they can take to 200A per Pack or 1200A for the full bank.

Maybe so you can set one for Lfp and one Fa? Or 12/24v? Or priority?

What made no sense is the controller was like any other MPPT controller but the pannel connection ports were tiny 14 gauge....can't fit 5 gauge in a 14 gauge port!

Max 14ga. wire is a Deal Breaker unless your array is pretty small, like a hobby set up.

14g..depends on the amps output. And not. Didn't even know they made a dual output charge controler. However a dual bank battery chsrger, yes. I have one of those that does 3 banks.

This charge controller professed 60 amps at 190 volts max....with 14 gauge wire seems to me you will have some fried wires since the wires coming from my 300 watt panels are 10 gauge to begin with then to run 40 feet the wires increase to 5 gauge then to fit 5 gauge into a 14 gauge slot just doesn't make any sense, all my other 60 and 40 amp controllers easily handle 5 gauge.
