Where to mount a second Battery??

[MZ-N10]

i dont think the engine bay has much room for another battery. so ur best bet is to install it inside the car, but tat requires u to get a battery box(if u dont mind an exploding battery i guess u dont need one). the only place tat might be able to hide a battery is in the plastic on the opposite side of the jack.

I'm of the opinion that you should mount any added mass towards the back of the car for better weight distribution.

Spazz's dual batteries under hood...

They will fit!

If you remove the stock airbox

I'm sure box will go bye-bye. He's putting a Morgan-Tec intake under the hood!

Ah, missed that part. As you can see in my VX, the Morgan-Tec doesn't leave enough room for an Optima, though, because it angles forward to use the stock air hole.

The nice thing about the Optimas are that they don't vent explosive gas like conventional batteries, so inside mounting is a breeze. A battery box is still a requirement to secure the battery and help prevent anything conductive shorting the terminals. A good location would be the rear-right corner below where the lug-wrench is stowed. You can easily route your cables underneath that interior panel and mount any isolators or controls in the lug-wrench compartment for easy, concealed access.

Ideally, any extra weight should go nearest the middle of the car as close to the center of gravity as possible. This will keep the extra mass from becoming extra lean while cornering. Of course, that should be balanced with the desire to balance the fore/aft weight distribution, as transio mentioned.

Actually, as close to the ground (or axle) as possible. If you add 1000 pounds at the center of mass, the car will still have more body roll than stock, because the force is a multiple of mass * distance from the pivot point (ground or axle, depending on whether you're calculating for suspension or tires). If you add mass at the pivot point, it is effectively neutral (if freely rotating) or can actually decrease body roll (if firmly attached to the frame).
