Have 12v dc scooter

[Jeffer]

To charge my dc12v scooter I'm plugging in the supplied scooter charger to a inverter that changes it back to dc to fill the battery. Is there a way to take dc power from my 200ah lithium house battery and go straight to scooter battery without using a inverter that has me flipping from DC to a/c back to DC again?
I have 400w solar and Victron DC to DC charging for my house battery

Victron orion tr 48/12. Assumes your house battery is 48v.

Do you know charge parameters for the scooter. I would want a charger and not a converter. The converter will have a constant voltage. The scooter probably takes a three state charger.

Staying with the (quality) factory supplied charger is the safer method. Unless you are very savvy to the ways of charging, and/or want to experiment and learn… always supervise the process.

What kind of battery does the scooter use?
