many many car alternators put out 13.8-14.3 DCV. thats close enough proximity to realize that a six or seven cell system is the limit for a series cell.
what that being said, why not take the variables out of the situation? my system uses a DC-DC converter. i drop my input voltage out to a steady 1-5DCV (depending on the # of cells and configuration), and the whole system could be plugged in through a car's cigarette lighter, even when running the cells @ 25 ampheres.
im not seeing the whole brute force dilemma others are. however- as bold and slightly cocky of a statement as that was, i have not measured my cell's current output in quite some time, or run them (in a while) as a matter of fact. my current cells are only utilizing 32 sq in per cell, making the recommended amperage only 8 ampheres per cell. i run them slightly harder, about 12 amps per cell, and run two cells in parallel (electrically) so that the chip i'm using only draws about 9 ampheres from the car's electrical system, and each cell sees the minimum voltage and max amperage.Statistics: Posted by resident_genius — Thu Jan 01, 2009 4:03 am
