Battery Charger Recommendation to go From Solar Panel on Van to LifePO4 Battery

Question:

Hi, dont have solar yet, even then I can only have 1.5 panels on my minivan ... so the 40A is the only choice as I only drive 2hrs a day at this time. The specs for this model support Lifepo4 .. My primary battery is almost new AGM and I want to install a 2ndary 100Ah Lifepo4 to run a 65W laptop 12-14 hours a day in car for work. I already have 8 gauge 10wire from the primary to to the 2ndary battery.. is there a setting on it that needs to be set to specify that my 2ndary battery is Lifepo4 ? or setting for the primary AGM? I cant see anything in the specs ..

The CTEK D250S that you referenced would not work for you based on your battery type which is a LifePO4 Lithium Iron battery. Instead you'll need the Redarc In-Vehicle BCDC Battery Charger # 331-BCDC1225D which can be wired to a solar panel like you have and can charge a LifePO4 battery type like you have.
