Cyrix-li-Ct with MPPT75/10

Hi,

Curently using a solar panel 100W associated with a MPPT75/100 to charge a 12V LiPo 55Ah pack.

This application if for an RV, so I plan to add a Cyrix-Li-Ct coupler to use the vehicule alternator when driving.I just don't know how to do it best.

1) Should the Cyrix-Li-Ct outlet (LiPo side say) be connected directly to the LiPo battery:

Hi,

Reading more about this topic make me think I may need a VE.Bus BMS controller ?

Is there any risk to over load the lead battery with the voltage coming from solar panel ?

Will the Cyrix- li-Ct work on a 2018 Euro5 vehicule ?

Maybe someone with RV experience could help

Thank's
