I have a 2019 TAB 400 with the solar package. We have been out for 7 weeks and just completed 10 days in the shade with no hookups and temps from 30-40F at night. On the Victron, the battery would go down to about 56% in capacity and I ran my gen 3 hours a day to bring it back to the mid-70s. We were running the AC/DC fridge on DC, heating with the Alde, and I ran my CPAP. We also used basic water, lights, etc. and we watched a video some nights. I am satisfied with the performance and my generator used about .75 gal of propane each day.
Now we are plugged in. The charger kicked in and quickly brought the battery to 76% in a few hours as usual. Now it is the next morning and I am at 83% on the Victron which shows that we are charging at .8A. I will get solar today as we are ideally positioned. In fact, we went 4 days in death valley without starting the generator so it works great.
But if we didn't, can I figure that the battery has 17% of charge to full which is 38Ah of the 224 Ah and at .8A, it will take 47 more hours to charge?
Would a different charger complete more quickly? What about the replacement factory unit with the program override pendant? Or an external unit?
Is it important to fully charge periodically?
Also, another factor I hear about Lithium batteries is that they charge more quickly. Something to think about?
I ask this because I have been arranging campsites with power for one or two days between dry ones to get the battery charged and other services. If I need two days to charge, I can figure that in.
I have learned so much here and we have had a very smooth trip as a result. Thanks!
