your build sheet will have this info
Only if you are planning to charge through the 7-pin. If you really want the best charging for your battery bank, bypass the connector with an anderson plug that's wired directly to the battery terminals (and consequently the alternator). 220A will flow into your charge controller on the trailer (use the solar controller) and pull what it needs to keep your bank full. Just make sure the wire gauge matches from the battery/truck wiring to the trailer/bank wiring. I'm waiting for a weekend at home to do the same setup on my truck/trailer.
Which engine are you asking this about? You asking about the alternator on a '22, but you said you ordered a '23. You could get a non-etorque Hemi on '22 models. From what I've read, the only Hemi engine option on '23 models is the etorque version. The reason I'm bringing this up is because there is no alternator on an etorque Hemi.
I am getting a 2023 Limited with e torque , if there is no alternator will have to worry about problems with Lithium batteries in my trailer?
Definitely no alternator on etorque. The 12v battery in the engine bay is charged by the 3kw DC-DC converter in the 48v etorque battery module. You'll want to do some research on whether you can use that system to charge the lithium batteries in your trailer.
What kind of trailer do you have? How big is the LiFePO bank? How many watts of solar do you have on top? How much more room do you have on the roof?
I do not have solar, and am planning on 2 100AH LI on batteriesWhat kind of trailer do you have? How big is the LiFePO bank? How many watts of solar do you have on top? How much more room do you have on the roof?
You've got a few options:
1. Wire the trailer to trickle charge through your 7-pin instead of an Anderson plug. It'll keep you topped off while driving but wouldn't charge your bank unless it was a really long road trip. How big is your Lithium bank on your trailer? How many Ah?
2. I'm assuming you've got a solar array on the trailer. Might be way less of a PITA to just add a panel on the trailer if you're not able to keep the charge level sufficient.
3. Lithium banks are awesome because you can use a lot more of the available Ahs and they recharge faster than AGM or Flooded banks. You might be trying to solve a problem that isn't real.
4. If you're still struggling to keep up, you can either increase your bank size or get a portable generator.
5. No more cold beer camping.
@RockYacht2020 - Have you installed your Anderson plug yet? Any details would be appreciated.
I think in one of the upfitter docs, it had a 50A limit from the rear ground point. 40A out after boost and efficiency losses might be as high as 70A in.
