I have a Truma solar panel which comes with its own mppt solar controller specifically designed to charge two batteries ( in my case car engine battery and habitation battery) I changed the habitation battery to lithium(LiFePo4). I want a programmable controller like Victron controllers. I bought Blue solar MPPT 100/20
Can I use the “Load” outlet to charge the engine battery? If not which Victron MPPT solar controller has ability to charge two batteries.
Many thanks
Muratti
