Charger: Meanwell 10a or Iota DLS 15?
This is a followup to the thread I posted a couple weeks back. I want a capable portable charger for a 100ah AGM battery bank, mostly fed by solar. The constraint is that my generator is limited to ...

I was hoping that temperature compensation(TC) would get a little more traction as a topic.
You see, it is a rare AGM where the mfgr fails to mention TC and post a table of appropriate voltages to match the battery temp during charging. OTOH, it is a rare FLA that gives any info on TC.
Jacking up the Volts is a wet/flooded battery charging practice because the only effect is to cause bubbling when the battery gets too warm.
We AGMers do not have that privilege. We need to pay attention to battery temp. That is why I suggested you get an IR gun so you can know when the charge Volts are too high, or too low. When the battery temp is higher that the chart suggests, we back off the volts and the opposite when the battery temp is below the chart.
Now, I don't wish to sit by my AGM and point the IR gun while manually adjusting Voltage on the charger. That is why I mentioned a charger with a sensing cable where the charger will monitor and adjust Volts depending on the battery's temp. You are free to move about. I prefer to maximize the R in RV.
The DLS does not know the battery temp either.
How about a portable $50 15A Schumacher from Wal-Mart? It has an AGM button. I used a 12A Schumacher for years.
