2023+ maximum 12v battery charge rate?

[phevGoBzzzzzz]

Hi,

For the new generation PHEVs, does anyone know how quickly the 12v aux battery charges when the car is in "Ready" mode?

I've added a 7 way trailer plug with the 12v pin connected directly to the aux battery, which I will use to charge a Lifepo4 house battery in the trailer while towing.

I want to know how powerful of an LFP charger I can hook up to that on the trailer side where the car can still keep the aux battery topped up.

Thanks!
