Cyrix-Li-Ct connecting 24V LiFePo4 battery pack to 12V Starter Battery

In my RV I will have 12V starter battery, but due to high amperages I think about making hotel battery 24V to cut them by 2.

If I connect Cyrix-Li-Ct on the one side to 24V battery and on the other to 12V starter battery will it work? Or it will break?

Is such connection safe at all?

No, this will never work. You better choose Orion TR series to mix up 24 and 12 Volt systems.

but Orion TR will not let me charge back starter battery with MPPT PV regulator set to 24V when I will have sufficient power. and will also not give me separation of batteries.


But I undestand that this mix won't work and probably I will leave 12V onboard and drop 24V idea down.

Yes, same with mppt charger, no mix up possible: output voltage can be 12v or 24v.

If you want to charge starter battery you'll need a second Orion TR 24-12.
