so ive tried the charger on a single batt (d3400) and a bank of 3 d3100s.
Whenever I turn it on it just sits at the screen that shows .6v stby.
No matter what ive done checking the wires nothing has worked so far. I used sky high 8g for the power wires. I have the controller, temp wire and power/ground all hooked up as far as i know correctly.
And it just shows .6v stby noatter what
