1V 100A will be very much hotter hotter than 100V 1A. but both have same Watts.
Low C ratings cause voltage ripples that causes the components in the esc to fail. Some esc's you can buy capacitor banks to fix this.
Thanks man,
see, this is an explanation that makes sence. Now I'm at rest :-) I'll Google voltage ripple a bit.
One quick question:
- Is there any risk/problems, in too high c-ratings? For a given car.
For me I would think, buying an even higher (better) c-rated battery for my car, is good as
- it gives a reserve if it over time looses some punch
- can be charged quicker
- can keep up, if I later on upgrade motor and ESC
Downside would be higher price, but there will be a "sweat spot" where a bit better battery isn't more expensive than I would pay.
