Hello. I have a Victron Orion isolated dc to dc charger. The 70 amp standard alternator feeds a 70 amp lead acid battery and via the Orion 2x100amp lifipo4 batteries in parallel.
When the engine is running I see27 amps going into the lithium batteries. However on the Orion it shows input 13.2v, and output 13.7v.
Shouldn’t the voltage be higher than this?
Sorry if it is painfully obvious, but it isn’t to me. Thanks.
It’s possible that you have it set up right, but are noticing a dc voltage sag since the charger is outputting current. Could you tell us the exact Orion charger you have and your battery model number? I can help guide you to ensure you have the right settings.
Thanks for your response. I do appreciate it.
The Orion TR 12v to 12v Blue smart charger has it’s input from a 70 amp lead acid starter battery. The output is to a pair of Renogy 100 amp hour LiFePO4 batteries.
I have set the charger up via the BT application.
I think that you are right about the voltage lag. I hope so anyway. I suppose I will have to see what happens on a long engine run. Not something I do that often with sails.
