ok cool. Practice > Theory.

yep that theory is completely flawed unless you were to use like 4 or 6 gauge

stick to 0 gauge and you will most likely not even have a .1 voltage drop from the battery to the front

sound to me like his expertise isnt electronics :icon14:

Definitely not and neither is it mine. If there is one area that I don't know enough about, it is electricity and conductivity. I have never studied that field sadly.

I have relocated batteries and also have used the PC680. Eventually I got back to just replacing OEM bat w/PC680 for weight savings in place. Why? Relocating means heavy gauge wire ('0' - '2') to carry the heavy starter current without voltage drop. Aside from the inconvenience of installing the wire, the potential voltage drop of extra connections, and PITA of stuffing the battery somewhere where it was not designed to be, but the bigger issue is weight.

The heavy cable actually weighs a considerable amount per ft, the new mounting bracket weighs more. Add that up and the battery and you'll find actual total weight saving diminished significantly. Leaving the battery in its original gets you the most static weight lost. The only downside is there is not fore to aft weight change.

The PC680 works good, but tends to discharge quicker over time than stock, and I've found they need replacing about every 2 yrs as they lose charging capacity.

Good info, I think you should buy a Z. We could use another voice of experience.

What is the point of relocating the battery to the trunk?

for better weight distribution....

Yeah, if you're moving all the stuff out of the trunk, moving the battery to the trunk will off set 45Lbs from front to back (roughly a 90Lbs shift). That makes a BIG difference in traction and handling.

How heavy is the pc680 battery? Aren't those batters a lot lighter than stock?

15.4 lbs

FYI. I found out that odyssey does not recommend the 680 motorcycle battery for this car... i'm not saying it won't work, just that when my shop called them - they recommended instead using the 925. The 925 weighs 26 lbs. I will be relocating the battery to rear also, which is even more reason to go with a slightly higher amperage option vs the 680. Rgds, Travis

Awesome, thanks for the info travis.

with 0 gauge wire, i guarentee there will be no problems out of a pc680

Do you buy battery boxes, or some form of containment when locating to the back? I imagine you don't just throw the battery back there.

actually with the pc680 thats not needed.
same with any other high quality (i.e. expensive battery)

These batteries are either dry cell or gell cell. this makes them impervious to leaks and means so can mount them upside down if desired
