I have a question:
If I have 2 x 100ah LiFeO4 house batteries with a charge rate spec of "1C" sitting at 20% after a rainy few days in the forest, how long does it take to charge these batteries via the truck engine when I start up and drive away, using the "7-way" connection?
I figure a 40amp DC-DC charger recharges them fully in 4 to 4-1/2 hours.
Doubt they’d ever fully charge via just the pigtail and no actual Charger.
However all this speculation, if one wants to figure it out, get an amp meter and see how your vehicle and and camper behave.
