Are lithium batteries worth the cost?
I can carry two group 29s in my AF1150. Are they worth it?

Not putting a DC to DC charger in the system carries the risk of two things. Discharged lithiums can pull max current from your (non smart) alternator which will burn it up and possibly cause a fire. Ending up on the side of the road is a big possibility.
Lets clear this one up before it starts spreading as fact.
The only way this is going to happen is is some one took the fuse out of your charging line for your 7 way. Or if some person who didnt have a clue installed there own because it want a factory option and didnt put a fuse in.
I think most of this stems from the youtub video of a guy hooking a li pack directly to an altnator with large wires and started it up using an electric motor. no fuse now voltage loss and yes it did start stuf burning.
having said that I still would encourage the use of a LFP compatable DC to DC charger and proper wiring to provide the LFP battery its best charging.

Well you just reiterated what I was mentioning. The proper way to charge Lithiums (with the truck charging system)is with a DC to DC charger and not unregulated with a smart or dumb alternator. Because the lithium battery will absorb a lot of amps if you offer it up. Not sure what you cleared up though. Facts are what we both stated. So thank you. :)
what I cleared up is that in reality if you have LFP batteries hooked to your charging system you will most likely be fine. the smaller fused charging line will only let so much go and it wont be enough to blow your altanator, and most likely not even enough to pop the fuse. is a DC to DC better, ya I would recomend them no matter what type of battery you have as a truck altanator throws out what it throws out... designed for a starting battery but it isnt dialed in for deep cycle, agm or LFP. it will work as the values are close enough but not optimal.
so realy unless your factory vehicle has been messed with you have no worries while you are waiting for a proper charger to install.
