I am very new to this. I've had a renogy lithium leisure battery fitted and the orion charger into my 2015 Peugeot Boxer, however the mesure battery just barely seems to be charging. There is 14+ volts coming to the charger when the engine is on, but the output maxes out at 12v, and the retained power in the battery is barely enough for an evening if very light use (an led light, occasionally the pump for the tap, that's it!), and not enough to run the diesel heater for more than ten minutes. I think I may just have some settings wrong but I've no idea what I'm doing - I've literally only downloaded the app today and done a but if research but got no further. Most obvious thing seems to be switching the setting to charger from power supply - is this right? And are any other settings incorrect? Please help, I'm in France and it's freezing! See pics.
Thank you thank you!
