Or a usb powerbank with a boost converter.


Newer powerbanks can charge laptops aswell so they can output up to 20V.

Obviously not hundreds of amps.

You have to communicate with them over the data lines, the protocol was simple from what i observed on a youtube channel.

Those guys didn't even know what they were doing. The second video with the truck is much better. I can see this being handy around a farm or country home, but the engine lacks the power to cruise at 55mph+ and climb hills.

It wouldn't eliminate the alternator or starter, but I was searching batteries one time and found some amazing lithium-ion batteries that packed a helluva punch and only weighed like 7 lbs! Of course, they were very expensive - some over $1000 - but that would save a bunch of weight! Then solar cells on the roof, and....

Well to buy and fix this car I'm only in it for $450, so 1k for a battery ins't going to happen.

I have a friend who uses a little 2 pound mighty max battery from amazon to start his 40hp yamaha two stroke outboard motor. Its like 700cc so maybe you could try something like that. His battery was only like 19.99 and reduced weight by ~60 pounds.
Past that... Pull starting my yam 40 is a big pain in the ass. I wouldn't recommend pull starting a car engine.

I'm not so much concerned about weight, I drive 80 miles of interstate a day with ~3-4 miles of 'city' driving, which is basically just from my house to interstate. The reason I was thinking about this was to eliminate the constant draw of a battery that can't be charged further, yet the alternator is trying to do so.
