Step up converter 12v to 19v

I read that someone serial coupled two 12v batteries to make the starter motor turn faster. 24v worked good he said. I don't know how he then charged the two batteries with the 12v stator?
My idea is to couple a 12v to 19v DC step up converter between the battery and starter motor. Then you would use the standard battery and only get 19v to the starter motor not the rest of the components. The charging won't be affected either.
Has anyone done this? Could 19V/10A, 190W be sufficient? A bit low maybe?

It's a good idea fundamentally, but as far as I know it would be hard to make it work in that way – the starter motor takes around 100 Amperes and I would guess it's hard to find an voltage step-up with that kind of current capacity.

However, it might work the other way around – have 2x12V batteries and a step-up converter to charge them. I can't speak with any authority though!

However, good LiFePO4 batteries are REALLY strong starter batteries and start these bikes really easily, even tiny ones. I've got an EarthX ETX12A in my 570 and it starts the bike without any effort at all. In comparison you could feel how the the stock-type lead-acid sagged under the load.

Off course! The other way around. To charge via an step up converter. That's better.

I think I will go for a LiFePO4. Sounds like the best option.

Thank you!
