O.K., if you want to be pedantic,
How much voltage do you need to pump approximately 2000 X ( 6.242 ×
1018^18) electrons per second into a battery.
If the battery is sized properly, 14.2 volts will get the job done,
maybe 14.4 for the first 70 or 80% if you're in a hurry.


Larry posted about people who had multiple 250 Amp alternators
installed. I simply asked how many volts it would take to charge a
battery bank at the installed 2,000 amps.

You seem to be saying that with 14.2 - 14.4 VDC the current flow will
be 2,000 amps, which would make the battery resistance about .00715
Ohms.

Somehow I don't think that is correct..

Hey Bruce,

Your math is correct.

The problem is that the internal resistance of a healthy battery is a lot higher
than that (which would limit current).

I know....
