    I would like to see that setup just for the sheer spectacle! Extra points if you have to keep the window open for the diesel-power indoor heater's exhaust pipe.
    Maybe it could employ a catalytic heater placed in the cargo area and circulating water through radiators in the cabin.

    Lithium runs at a higher voltage than household batteries. There are a few dual-power devices (I've got a little flashlight that runs on a AA or a same-size lithium-ion which will make it substantially brighter) but in most cases it's one or the other. It's also possible to have a device that runs on 3 standard batteries or one lithium-ion--an almost perfect voltage match. I recently bought a headlamp that works that way but I've seen very few devices of that sort.

    Reminds me of the gasoline powered heaters in VW Beetles.
    When conservatives realize they cannot win democratically, they will not abandon conservatism. They will abandon democracy.

    Poverty exists not because we cannot feed the poor but because we can't satisfy the rich.

    I'm specifically thinking of the current crop of e-bikes and am less concerned about cars (although the cars are obviously a much larger market).

    I have a 12v electrical system on my velomobile that runs off a battery pack (3.4 Ah, I think) that's just an 8 pack of rechargeable C batteries (NiMH, 4 inline x 2 parallel). Looking at velomobiel.nl, it looks like my older battery pack is already obsolete compared to the newer, smaller (and more Ah) system.

    Your wiring is wrong--that's 8 inline. 4 NiMH inline x 2 parallel would be a 6v system. You could get 12V (actually, more like 14v) out of 4 Li-Ion x 2 parallel but that needs a reasonably sophisticated charge controller to keep from blowing it up.

    Could you chew that a bit finer? So if I buy a lithium battery as opposed to your standard battery I shouldn't be using them in the same device, like a flashlight or headlamp?

    The lithium that you buy as a replacement for a normal battery is a different chemistry, it works fine. I'm talking about the rechargeable chemistry, that runs around 3.7 volts compared to the 1.5 or less of an ordinary battery.
