Hi, I had a marine installation with a simple alternator feeding a lead acid starter battery and a VSR feeding a lead acid house battery, all negatives running to a 500amp Victron Shunt and working well.
I swapped out the LA house battery for 280Ahr Lifepo4 and swapped the VSR for an Orion 12/30 which charges at 20amps for about a minute and the drops to 1amp or less on a battery with a Low state of charge warning running. Battery is about 12.7v, charger shows input of 14.3 and output of 14 but shunt shows 12.7. wires are the same guage as previously and the cable run lengths didn't change... what settings have I not used correctly?
