Question 1:
In most examples I read that a shore charger is connected directly to the battery and not on the input of the Argo Fet.
Why not connect a charger to the input of the Argo Fet and charge all 3 sets at the same time?
Question 2:
I have an old but still perfectly working Atlas Combi 12V 1500W 50A. When adjusted to 14.4v, can I use this charger to charge a 4s LiFePo set? Or doesn't this charger have a flat voltage output but somekind of a 'lead' rimpled voltage? I don't mean the voltage difference between float/bulk etc. But the voltage output.
