I'm in the process of installing a LiFePO4 battery in my Roadtrek class B motorhome. It's a Mercedes Sprinter chassis. The LFP battery will replace two lead acid batteries which were able to be charged from an onboard inverter-charger and also from the alternator through a battery isolator. To protect my alternator, I'm installing an isolated Orion-TR Smart 12/12/30 DC-DC charger. This was based on my research regarding some of the electronics I have on board. That said, the ground of the engine/chassis battery and the 'house' (LFP) battery is common. Is this going to be detrimental to the Orion? Thanks for any and all advice you share.
