I can set my DN to charge 4 batteries at .5 amps each, plus it conditions the batteries while it charges them. I actually used to know all this stuff, but I've been away from it for a while so I'm trying to clear out the cobbwebbs.
I do all my charging with the DN using an AC adapter. Not sure what the green connector is for, I've never used it and I don't have the unit with me to look at it.
Cobbwebbs! You have come to the right place to get help clearing them out.
I come here to get mine cleared out, regularly!
Your calculations look good to me, as long as we are talking about a 500mAh battery. Go to 550 or 600 or such, and that changes things a bit also.
What happens when you hook up 4 600's? Less charge per batt, or overload the charger?
And as Brian says most chargers have a banana jack output. Mine has both, balance and banana jacks. 1S batts I can charge straight from the banana jacks. 2S and more have to be hooked up to the balance connector also, or my charger will alarm at me. So I was wondering what the green connector was, is it output?
