So... I have a solar-powered Tesla in that it is charged primarily with solar power from an off-grid system.  My adult daughter is the main driver.

I happen to drive a Big-Ass-ICE-SUV that recently decided it was very un-motivated to start.  Prod it a bit, give it some time, and it would start.  While I was waiting for a replacement to the 10YO lead-acid battery, I needed to jump it and was in a hurry... so... obviously a Tesla should be totally capable of doing that right?  Not just one, but _two_ battery systems, 100kWh of energy, outputs tons of power, has 12V [or 16V] terminals, ... 

Well... no.  My daughter said "can't do that" and so I grabbed a 12V LiFePo4 battery I had around and jumped the car with that.  Bought a little jumper box so the Tesla could be friendlier to ICE vehicles that needed a jump.

End of story...

Of course not... stupid Tesla has a weak-ass battery system that can't provide like 100A to a poor stranded ICE vehicle?  Bet it can't power anything requiring more than an amp @ 120V either.  

So given I specialize in putting solar and battery systems into boxes... and the M3 Tesla frunk is just a weirdly shaped box... I produced the bespoke 'system' shown in the slide show above.

Functionally it is a 12V 100Ah BG24 LiFePo4 battery, 500W+ AC, 2x240W DC (normally), and >12V charging source (solar or 16V+ battery source) 'generator system', but because the battery is semi-exposed it can easily source 1200-2400W DC to help jump start an ICE vehicle.  Everything is bluetooth capable so can be monitored from inside or outside the car with the frunk shut.

Designed it so it simply bolts in to the car (swap out two bolts for longer version) and into other pieces.  Goes in and back out of the frunk in less than an hour.

Stupid system, but was fun to deal with space constraints.  Probably will move the major components into a normal toolbox build unless my daughter wants it.
