Charging a 48V hybrid battery system

I’m currently looking into the pros and cons of replacing my diesel E class estate with a petrol version and might consider one that has a 48V hybrid battery system. Does anyone have advice on a top-up charger for the Mercedes 48V battery pack?

The mild hybrids can be jump started from a battery pack or second vehicle via the 12V connections under the bonnet. I assume that the bidirectional inverter charges the 48V battery in that case so any good 12V battery charger should suffice to keep both batteries topped up.
