Hi all,
I'm planning to set up a DC-DC Orion converter to charge a Victron LiFePO4 house battery in charger mode (coupled to a starter battery, the latter powered by an alternator). Does the chemistry of the two batteries have to be the same? In other words, do I have to replace the engine starter battery with a LiFePO4 starter battery (for example, a pair of DL+ 12V Dakotas for a 24V system)?
Hi @romeobravo
Simple answer: No, the chemistry of the starter battery doesn't matter. It's all about the input voltage.
@Stefanie (Victron Energy Staff) Can you please explain more or show a diagram how i can connect a dc to dc victron and other components to make the dc to dc set up more safer and reliant. Thanks
@MannySantana78 Here are some system schematics available for download: https://www.victronenergy.com/dc-dc-converters/orion-tr-smart#system-schematics
Also the manuals contains some simplified schematics to get the basic functionality correct.
