Great charger poor delivery choices

I have one of these charges and ordered another to keep in the office. I have yet to receive the other one as fed ex refuses to leave it with my apartment management office. Apparently this was shipped with direct signature required. I can’t order items unless someone else can sign for it, so Luna has lost my business. It’s too bad because I like their products, but they are no good to me if I can’t get them.

Great very smart charger

I have a amp watt meter connected when I charge, and you can see it starts out at 2.5 amps for awhile and then throttles down as it goes. Toward the end it may only be putting out a fraction of a amp. sometimes you can see fraction of a amps go up and down with it trying balance the cells out. You can only see it if you connect a watt/amp meter in between the charger and battery.
