Jump starting with LiFePO4

Not really.
Most manufacturers omit the rear pump, so no way to get fluid pressure to spin up the TC.
OLD fords could, some mopar, and mercedes autos...
But yeah, need a HILL to get enough speed to spin it up to start pressure.
There was a story about a guy who needed a push start but his car was automatic. His friend had offered to help, and they were talking about how you could do it, but "you had to get up to about 30mph." So they jump in their respective cars and the guy wonders where his friend went, only to look in the rear view mirror to see his friend approaching at about 30mph.
 
How about one of these it's not cheep but it's blue 💙 and color coordination half the game.
Not the devices intended purpose but puts out up to 15 volts and at a solid 30a should raise SOC of the FLA starting batt. Enough to get you rolling in 10-15 min. Just add some fancy quick connector plugs an on board interface and some custom warning labels. So many possibilities.
And it's Blue! 🥰

Clever!

Back in the day, this would not have been an issue. If you had a stick shift, you could always push start the car with a friend. 😁 😁
In my owners manual I found a "rolling start" section and I was excited thinking it might be for bumping the engine to start it. But the truth was they just allow pushing the starter button in neutral while rolling lol. Not sure I'd need to do a rolling start unless the starter is busted, but OK lol.

Hey blue is my favorite color I've invested in some of that blue stuff it's incredibly reliable you usually get what you pay for.

I was trying to come up with a cheap DIY hack that would not put $1000+ worth the of equipment at risk, since no bells were ringing I though why not through a $400 solution at a potential problem that we hope never occurs and can easily be avoided.
It's kind of like half the crap in the back of my Van 😄 🤣

I thought of one. If you do a lot of camping and tailgating and you're into your own DIY hacks
Interrupt your accessory and interior lighting circuits at the fuse panel cut in a relay and wire in a low voltage disconnect to prevent the problem from ever occurring in the first place.

This can all be done and hidden under the dash or in the engine bay wherever those fuses reside without modification to vehicles electrical system 🤔 being it was still under warranty or a lease no snip-snip.

I was able to roll start my 2010 VW TDI, (one of the last diesel manuals platforms you could buy). Even with all the electric sensors and systems, she still fired up. Live on a hill and thankfully the garage floor is sloped and I was able to make a backwards full turn and pop the clutch once pointed in the right direction rolling down the hill before needing to come to a stop on our blind driveway. It was one shot and I nailed it and made my flight.

Looking at the date today (knowing the car would be 14 years old if VW did t buy it back and then crush it) I sigh and admit you could say it was back in the day.

Always a plus when you are up on a hill. (y)

Yes, an option. 😁

Had issues with key not making starter crank, so hardwired pushbutton to solenoid for my Saab 99LE.
One day the clutch fork broke.
I shifted up and down gears without clutch, came to a stop at light stalling the engine.
Light turns great, push the "crank" button, hit the gas, and it started and took off. Got home without a clutch.

Put same in Sable because my wife reported it wouldn't crank (maybe shift position switch issue? Or just shift position issue, or not standing on brake?) Haven't used it yet.

305 Superhawk, clutch cable broke in LA rush-hour traffic.
I shifted up and down without clutch, popped it into neutral at the lights.
To start, use toe shifter to put it into first (bit of chain slip), crack the throttle, drive on to next light.

The hand lever had a groove for cable, but a sharp angle in it. After buying a cable and completing trip, when I got home, found the problem, used a hacksaw blade to change angle into radius.

Other cars, I've also run gears up and down without clutch. Even cars with no synchro.
