I have a 300ah lithium battery bank. I charge it from shore with a Multiplus 2 3000va at 14.4 volts no problem.
But...when I charge from the Orion 30a or a MPPT 100/50, I get current running but the voltage doesn't rise above 13.5v-13.7v, but the batteries do get charged and are topped to 100% SOC. Is this normalno for both to not be able to produce 14.4v? My Orion is showing my alternator pushing out 13.6v-13.7v and around 300w current. My solar panels are two 320w panels in paralell at 42.5v, 450w current on a sunny day.
I'm under the impresson that lithium needs to be charged at 14.4 in order for the chemestry inside to work, will chargin at a lower wattage still push power into the batteries and how safe is it? and should the Orion and MPPT get up to 14.4 in normal operation?
