Charging my Trailer batteries from the RAM eTorque with a 60A Renogy DC-DC charger

[PedroD]

I am exploring charging my four LionEnergy LiFePO4 batteries in my trailer while driving using a Renogy 60A DC-DC charger. It seems as simple as running a AWG2 from the battery terminal in the RAM to an Anderson clip mounting in the bed. Then connecting that to an extension through the camper to the batteries. My concern is the eTorque 48V system. Would I create any issues while driving by adding the 60A draw to the truck?

I have the same question. I have a slide-in camper with a 100ah lithium battery and a Victron 30 amp DC-DC charger.

You'll have no problems. I have my Renogy MPPT DC-DC charger and a Renogy 100 amp hour battery mounted in my driver's side Rambox. Ran the cable from the positive battery terminal under the hood to a circuit breaker mounted to the back of the ECU and then back to the Renogy charger. You will have to run a wire from the IGN+ terminal of the Renogy charger to a ACC triggered 12v source on the truck since the Ram is equipped with a smart alternator.
