Which alternator does the 2021 R-31CB come with?

Hi Factory.

What alternator does the R-31CB come with and how many amps does it output?

I'm trying to estimate charge time from say 50% or lower for the batteries. I do understand that lead acid charge time is not linear.

Thanks

Mark.

Quick search shows the d4-320 has a 12V/150A alternator, probably the same as the d3 etc.

Thanks. That seems small for such a beefy engine with that much torque. I'm curious if anyone upgrades these. Might cross post in a tech forum.

For example, I'm busy upgrading my 1994 Dodge Ram 2500 project vehicle which came with a 130A alternator to a Nations 270 amp alternator. If I recall the new Dodge Cummins have an option for dual 220A alternators for 440 amps total.

I'm interested in potentially going over to lithium so I'm just researching my options.

Thanks again,

Mark.
