A battery is a battery is a battery. Here's a little experiment you can try at home with something cheap.
Find something that is powered with one small battery that requires little to no amperage, measure your voltage and current. Now go out and get like 30 or 40 of those batteries and hook them all up in parallel and see what you voltage you have. Now hook that parallel bank of batteries up to your device and measure voltage and current again.

if you reread what I said, you are taking the chance that there is no weak part in your system. I have seen it happen with my own eyes. I have worked with mechanics that have 20+ years in the field that can back me up.

ask any EE if you can jump a bike with a car battery, in theory it works, in practice I have seen electronics fried. |

just because you have never seen it doesn't mean it can't or hasn't happened.

I am that mechanic, I haven't flipped burgers since working in the mid 80's.

yes I do understand that with a perfect system that you are correct but every time you hook it up to a car battery you are taking the chance that the manufacturer that built those parts the cheapest didn't put one of the parts with a lower tolerance in your bike. giving out advice that it can not or will not damage the bike can be incorrect. that is all I am saying. it can damage a weak link in the system.
