Hey all, I realize this is a super basic question, but I imagine someone here knows the answer quickly, and I want to make sure before making purchases.
Would it work to connect the 15amp output of a lithium inergy kodiak portable battery to the input of a dc-to-dc charger that is 30 amps?
I'm not concerned about the lithium battery, more the gauge of the female cigarrette lighter ports / wires to them. Maybe I could use an inline current limiter or something?
More context: I want to charge my van's 200ah agm house battery off a portable lithium battery I already happen to have a 90ah inergy kodiak. I am looking at buying a DC-to-DC charger such as a Victron Orion, and considering going with a 30amp model instead of say the 9amp one, in case I want to upgrade the house battery to lithium in the future, and use it for alternator charging.
Even more context answering "why": my motivation for doing battery-to-battery charging is that solar alone is no longer sufficient for keeping my house battery charged, and it is necessary in the winter to keep the webasto gasoline heater running, to avoid the water system freezing. In the meantime I have the van trickle charging at 2amps from grid power, and this seems to have done the trick. However, I want to have more flexibility in parking locations.
