As a new RAM 1500 is likely in my future, I'm interested too, but like any new technology, if I were buying tomorrow, I'd just buy the 5.7L Hemi and let them tweak he mild hybrid system for a year or two first.

Does anyone know if the lithium battery built into this system can power the accessories within the vehicle?
Looks like that battery can store up to 430wh and since there's a separate lead acid battery, I would guess you can completely drain that lithium battery without any worries.
This could be very useful for those who camp a lot if the 48v lithium battery converts to 12v and directly hooks into accessory power ports.
Lithium batteries do not like to be completely discharged. Chris
Never had a problem discharging all my tool batteries.

Even if the 48V system was available in a "key off" scenario, the 430 watt/hours of capacity-about 1/3 of a standard RV battery- is too little to be of any real use.

Sounds similar to the early Prius hybrids.
Great if you are primarily using the truck as a "grocery getter".
But probably not much of a benefit while towing. The problem is the boost time is likely limited to tens of seconds or at most a couple minutes. So great driving in stop & go traffic to work or if you need a little surge to pass quickly on a 2 lane road...but climbing a 5 mile grade, your available power is what the ICE generates.
A plug-in parallel hybrid with a tow-haul mode would be interesting but I suspect there isn't enough of a market for it as the vast majority of 1/2 ton pickups do no significant towing.
- Example: If you have a 20mile electric range and you are allowed to manage it, you could hold off burning thru the battery until you get to the base of a long climb and then use the battery power to assist the ICE getting up the grade. That might allow a basic V6 to compete with a V8 in terms of tow ratings.

I doubt the RAM will have a DC/DC converter to produce 12 volts like a vehicle that runs just on battery power. If the engine runs 100% of the time there will be an alternator that supplies 12 volt power.
Either way there would be a BMS to protect the lithium from over charge or over discharge.
