If its tiny, it cannot possibly generate juice as fast as you are using it. running an ICE generator on board, solving the fuel safety, fumes, and exhaust issues while driving is a pretty big challenge for both safety and space.
way more cost effective to buy a decent set of lithium batteries.

You nailed it on all three points. I would need at least a 10KW generator to propel the car indefinitely. Go price one of those out - probably in the $3K-5K range for a diesel.

Thanks, Ben. You are definitely in the credits as inspiration provider!

I agree 100%. I long for a LiFeP04 pack in the worst way. It's just that, well, my pack was free and continues to be free as batteries die and I replace them with more free ones. The point of this build is super low budget, so free wins. I agree that lithium is the cheapest battery you can buy (cost/cycles), but not as cheap as free!

The duct tape is only on the inlet to the blow dryer guts to act as a dam and force all blower fan air through the coils. I disassembled it today to inspect it and it looks like the day I stuck it in there.
I have been pre-heating with a 120V space heater that turns on with a timer this last week for about 45 minutes before I leave for work. My EV heater nicely maintains the coziness all the way to work.
Today I installed my poor man's BMS - a remote set of six volt meters that I can plug into the car to monitor each 12V pair while I drive. On my commute home I quickly found out that I had a dud pair. So I split them, load tested them and found the culprit. Back to the battery shed tomorrow, I guess.
I will post pictures of the "BMS" when I get a chance. It's pretty epic!
