Default optimal battery placement?

was wanting to relocate battery in the trunk, but also thought of relocating it to rear seat area or in the cabin somewhere. Wondering whats the best place to put the battery for optimal weight balance. thanks

was thinking of a very small batter under the passenger seat since the battery need too much power(no radio, no power door locks or windows)

....I guess you really didn't think about it much yet....or haven't studied much about polar moment of inertia or center of gravity.....or any of a host of other areas of vehicle dynamics....like I did........

....in essence.....lighter and lower, and closer to the center of gravity is best.....can't get any lower, and you could get the non-metal jacketed version of that battery and save another pound or 2....and it's a LOT closer to the center of gravity than under the hood or in the trunk....but that's about it.

....that is a wallyworld special HD insulated lunchbox with plastic top/bottom that I got for ~$6.....and THAT was one of the hardest things to deceide on/find was what kind of box to put the damned thing in ....really......fits just about perfect under the seat.......friction fit ya know ......with the seat all the way back, there is NO WAY it is coming out without the seat coming out first....the grey connector is like the ones used for golf carts to charge them....~$15(silvered contacts ) and the cable is 4ga oxygen free power cable....the ground goes to the seat rail mount bolt and the POS goes up the center console----under the HVAC and out the firewall above the brake pedal to the POS in the underhood fusebox.....I left the cables under the hood in case I ahve to put a regular battery back there for some reason.....once I had all the parts/pieces in one place and the connectors soldered....the install took an afternoon and early evening....the whole thing is 100% fab'd....right down to the 24k gold plated bling tab I made to attach the ground to the seat rail bolt

....nope....no electrical issues at all....ever......ya just can't leave anything electrical 'ON' with the engine 'off'. The Odyssey battery dosen't have any problem with being deep cycled or rapid charged/discharged, either...


......and the spot under the hood that was occupied by the battery makes a great place to put the water injection bottle and pump, too

10ft of neg? ----More hell no...2 feet MAX
terminals? ----copper solder on 4ga ring terminals
distribution block ------hell no, use the underhood fusebox POS and just make a grounding kit
quick connect switch -----no....just the plug, an Anderson SB 120 http://www.andersonpower.com/products/mp/sb.html
thanks for the help

If you took your battery and the tray out, your would look just about the same as mine.

.....there is an actual mount for that battery that would pass tech.....http://www.odysseybatteries.com/pc680hd.htm

These are VERY popular batteries for so many apps....must be some reason

That is FAA approved....so it better be good enough for whatever sanctioning body tech's your car

I chose the 680MJ that has a metal jacket.....there is a non-MJ----no metal jacket version that would save ~2 pounds. the 545 would work, but I chose the 680 as a better daily use battery.
Read the below stuffff and see what ya think.

All the specs/styles/BS can be found here....http://www.odysseybatteries.com/specs.htm.....and here....http://www.odysseybatteries.com/files/techbook.pdf

What about this battery?
http://www.batterywholesale.com/batt...ml?prodID=3027

same specs, sort of a replacement for the PC680. It's half the price but I wonder if it would work as good in car (instead of motorcycle).

....accept no substitute.....and you can find the Odyssey on ebay for only a couple $$ more than that price, and you KNOW it works, won't leak, and has a 3 year automotve use warranty...what more could ya want????

...don't be a cheap bastard
