Hi
I'm looking at moving from two lead-acid leisure batteries to lithium and am wondering how to address the connundrum that I have.
Currently both the mains charger and the solar chargers charge both the leisure and vehicle battery which is no problem as they are all lead-acid.
However, if I change the leisure to lithium this then poses a problem for me.
The current solar charger I have it this one coupled with a single panel - https://www.solartechnology.co.uk/product/10a-dual-battery-charge-controller/
I could change it for one with a lithium profile and dual charging - https://www.solartechnology.co.uk/product/15a-mppt--dual-battery-charge-controller/
I have been told by the supplier that I would have to leave it on the gel / lead-acid setting as it cannot handle two different profiles.
Fogstar have told me that this could causes problems with the lithium battery BMS.
So, do I just leave the vehicle battery disconnected? Do I really need to solar charge the vehicle battery?
I would prefer to as I do not have an EHU when in storage and I believe that the MiPhantom draws from the vehicle battery.
TIA
