Battery Relocation

[Lil Mike]

you defiantly want a proper hold down, im with lost on this one 100% so many ass clowns just put them in the marine box and butcher the shit out of them. i would use at least a 2 gauge wire.

with a 4 gauge wire you might have problems in the winter starting your car due to the voltage drop along the long wire. i would just get 2 gauge welding cable.

the factory ones do more then keep it from "rattleing around" in a crash they hold it in place still becuse there ment to keep more problems happening after a crash, sparking batts can cause a large problem after a crash and can ignite.


not to mention you keep saying how a 40 lb batt could kill you flying threw the air, well if you have hit something hard enough to send a 40 lb batt to break threw steal tie downs, a plastic batt box, the back of a seat and 8 feet into your skull then you probably have other problems on your hand as a normal persons body weighs 135-190 lbs and if a 40 lb batt can move that much amagine whats left of your body.

also not mentioning the fact that the angle of aproch would have to be perfect, most people mount the batts in the spair tire wheel well or way off to the side were the rear strut tower is in the way, so the flying batt would have to make a 45 degree turn in mid air

the reason it flys through the air with that much force is the fact it's moving at a high rate of speed, even though the car is stopped, in a 30 mile an hour crash, it will hit the back seat with the force of apx 3/4 of a ton, All i'm saying is you need to use strong enough tie downs to make sure it never moves, in a crash you exert thousands of pounds against the seat belts, the reason it doesn't kill you, is the human body can take hundreds of G's of deceleration for a very short duration. anything in the car will continue to move at the same speed you were moving, even though the car has stopped in the collision, the more mass the object has, the harder it is for it to stop. If you watch that video again, that tool box probably doesn't even weigh as much as an average car battery, you can see the amount of damage it did, with the amount of force generated in a collision, lightweight hardware simply isn't going to be able to contain the object. I'm not running anyone down here, I'm simply trying to point out some information on crash dynamics, I don't want to see anyone killed by something that can be prevented.

that right there is what im talking about

[labeledsk8r]

i know how crash dynamics work and know physics aswell and inertia and all, but it doesnt take much to keep something from moveing, if its tied down with steal tie downs like factory they will stop if not drasticly slow down the inertia. same reason the spair tire is held down by only 1 bolt but somehow has never flew threw a car and killed someone

edit** yep cah thats exactly what i mean

double edit** cah just brought to my atention the 3g uses the side strap style tie down these are trash lol the top tie down bars are what i mean and recomend useing, i forgot i changed out the ones on my 3g for that and my 5th allready came with that style

[stat1K]

i'm sure a spare tire has flown through a car and killed someone, hell i heard from a cop i knew about a lady who lost an ear from a kleenex box, no shit.

makes me want to go get stuff to tie down all my spare tools and such, i need to just take them out of the car as i don't need everything to replace an axle on the side of a highway but i like to be ready in case lol...

as for the tiedown, i wouldn't do it longways like in cah's picture i like the side to side setup across in between the terminals, that way the cable and the terminal will also slow it down in case... i also have 90* mounts on the body of the car to hold the battery from moving forward or back. i've had to stop pretty fast and mine hasn't moved a mm.

i used a marene box and 4 bolts with fender washers i bolted it right to the trunk floor it shouldent go anywere
