Solar charging my mobility scooter.

I have a 200w 12v (22.4v open circuit) solar panel on my mobility scooter and I need to use it to charge 2x 105ah lifepo4 batteries in series. I can not change the solar panel due to physical size restrictions.

What I currently have is

2x Victron Victron SmartSolar 75/15 MPPT Solar Controller - InBuilt Bluetooth

1x Victron Orion 12/24-10 DC-DC converter IP20 on the way.

What are my options please?

None of that gear is useful to charge your 24v Lithium battery.

You need a boost charge controller. Something similar to These boost controllers.
