12/12-18A vs 12/12-30A DC-DC

Hey everyone,

I'm piecing together a kit to upgrade our 2021 Greyhawk 27U to Lithium Iron Phosphate, and trying to source the right DC-DC charger. Does the E-450 have a 60A alternator that would justify the extra cost for a 30A charger, or should we stick with the 18A?

Tried to Google my way to the answer, but couldn't find the stock alternator part for the 2021 E-450.

Thanks!

The 2021 E-450 has a 210A alternator. I would choose a DC-DC charger with the highest maximum charge rate that I could find. It will likely have a way to limit the charge to a lower rate if you want to. I have a Renogy 50A DC-DC charger and can limit it to 10, 20, 30, 40, or 50 A.
