I'm trying to charge a Li-Ion battery (not LFP) with a maximum voltage of 16,8V
Using a custom battery configuration, I can set all charge voltages and currents within the solar charger as needed for this battery (12V config)
But when I enable the charging the solra charger does not charge the battery (panel voltage > 20V, battery = 16,22V). It reports the battery status as OFF.
Any hints what to do to charge a Li-Ion battery?
