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.
My Fords as far as I could check had all #10 charging wire and 30 amp fuse, or on 2017 breaker.
Breaker seems to be oversensitive, but I never really put meter on it.
Where would you put B2B charger? That will make big difference.
You can't draw 40 amp from 30 amp circuit.
30 amp time 4 hr gives 120 Ah (less heat loses) but charging amp are not linear.
