Like others above are saying, that's your problem right there.
For an RV charger/converter to deliver the full amount of current it is specified for and capable of at it's specified output voltage into a battery (that can accept that amount of current early in the recharging process at that voltage right on the battery's terminals), the voltage on the terminals of the battery must be as close as possible to the voltage you measure right on the charger/converter's output. This simple-sounding requirement is seldom mentioned in the advertising or specifications of charger/converters.
Use whatever size cabling and/or mounting proximity it takes to reduce any voltage drop between the charger/converer and the battery to as close to zero as possible during the early stage of charging.
Yes, that was the first voltages I read. I then jumped it with the 4 gauge and the voltage drop did go down to half a volt and never seen higher than 13.70 at the battery. Well, its higher now but that is after running it in boost mode again. I need to do what all of you are saying. I'll run number 2 and supplement the charging at the battery. The SG is now at 1.250 and its been about 21 hours.
As you said the distances were not mentioned and it did cross my mind but the seller said it would work even after explaining that I want to boondock and run only a generator and recharge as fast as possible.
