    (answered) Battery-to-battery charger with higher amperage than source?

    Update: * Running the van's electrical off of two of the kodiak's 15A cigarrette lighter plugs worked pretty well. However, after a day or so the webasto (air top evo 40) was still getting upset about low voltage, even when the inergy kodiak was on an 8A charger. Unfortunately that heater is...

    On further thought, you do bring up a very good point. The heater draws less than 15A so I could run it directly off the kodiak's cigarette lighter. To be safe, I'll try running it off of the two cigarette lighters in parallel. I think I went down this charging rabbit hole due to wanting to...

    True! I'm not actually using the inergy kodiak for solar, though I did intend it for that purpose when I got it a few years ago. Instead a renogy rover 60A + 480W of panels connected to the 200ah AGM battery. It has a battery isolator for alternator charging (the DC-to-DC is only required for...

    Ah, new plan! I'll get a renogy 20A dc to dc charger, then raise the LC current limiting input of the dc-dc converter, which should switch the charger to 10A mode. The input will be protected by fuse. If this doesn't work, I have the option of using the other cigarrette lighter output of the...

    Awesome, thanks so much sunshine_eggo and mikefitz! So I guess the 9amp one would be perfect. Bit of a bummer because I like the idea of having a more powerful charger for future alternator use if I upgrade to lithium (instead of current battery isolator).

    (answered) Battery-to-battery charger with higher amperage than source?

    Right, I'm not anticipating 30amps of charging rate. My question is whether the dc-to-dc charger will try to pull too many amps from the car outlet on my portable lithium pack, which is rated for 15amps. Lets say the wires inside the kodiak are too thin to handle 30amps. I'm concerned they...

    (answered) Battery-to-battery charger with higher amperage than source?

    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...
