I have an Orion 12/12-30 non-isolated DC-DC charger connected to a starter battery, supplied by a 90A regular alternator. I'm charging a 300Ah LiFePo4. Alternator is putting out 14.4V. There is a 8AWG wire running 5 ft to the charger, and then a 10AWG run to the LiFeP. With the battery SOC at 76%, the charger goes into bulk charge mode at 13.7V, but my Victron Smart Shunt is showing at most 14 amps.
I tried changing out the connections - 6AWG direct from alternator to charger and 8AWG back to the battery - with no meaningful change in charger output. I've tried multiple setting changes including raising the Absorption voltage to 14.6, turning of engine shutdown and input lock-out - nothing changes the amps I'm getting to the battery.
Looking for advice on what I can do to get closer to 30A from this charger. I've looked through the forums here but have not found anything else to try.
