It looks like your question was put in the wrong category. It was moved to the heavy trucks this morning.

You're wanting to put in the Lithium batteries? You can use them in this truck. Some of the new Cascadias are already running these batteries that have the green Tripac electric APUs. There is no issue with runningthem at all.

On how the alternator is controlled, it depends on the engine. Usually the SAM controller or the MCM controller will control the alternator. The alternator has a built in trickle charge as well so if the batteries get too low, it will charge the batteries slowly. That is controlled in the regulator in the alternator, but excited by the MCM controller.


You want a 5 star service and I want to provide a 5 star service. Please consider that I don't know your skill level as well as I can't see, touch, smell, hear the vehicle/machine in question. Please provide as much detail as possible and I will provide as much back.

Once an answer is provided, you should see a rating screen. Please rate my personal service to you. The ratings are my personal feedback,

they are not the site feedback.

Thank you for allowing me to assist you through Just Answer!
