-The base alternator is still a 157A single unit on the 6.7L.
-Extra Heavy Duty Alternator (220A single unit) is the first possible upgrade:
Required on any truck with the snowplow package
Required on any Lariat and up trim truck with the upfitter switches OR 110v outlet
Required on any XL or XLT truck with the upfitter switches and 110v outlet ordered together

AFAIK, if your LFPs want more amps than what the 7-pin can supply it will just blow the fuse on the pin # 4 wire.
Not clear what you really want for a set-up here. Once that is clear , there will be a number of ways to do it.
BFL13, which altanator did you have and how do you like the preformace of your DC to DC?
I am trying to decide what one to get. I have the 220A alt and I want to wire it to the upfitter switch so I only have it on when I want it to be on, but not sure of I should go with the 40 or the 60Amp
