I have a camper from 2011 and want to replace the current house battery with an LiFePO4 battery. Now I realize that there are quite a few modifications needed before I can install an LiFePO4 battery. My question is whether I can use a lithium battery as a kind of power bank for the house battery by using, for example, an isolated Orion-TR DC-DC battery charger?
Since I have lithium cells available and have experience building a battery, that's not a problem. However, I cannot determine whether the Orion is suitable for this purpose or if there might be an alternative unit available to achieve this. In my case, this would be a more cost-effective solution than modifying the entire setup.
