New converter PD4655 doesn't go into boost mode Part 2

What was the amps at 13.8v when you shut it off
Two hours might get you 80 percent charged
If your down to 45 percent you have to return about 140 amp hrs to the batteries that's not going to happen in two hrs
Not even with my 70 amp PD
Not saying your PD is working correctly,
Just saying your not providing all the info we ask for to say what wrong
