Where to mount a second Battery??

[CrzyFool]

I would like to have an Optima Yellow-Top to power my electronics (600w amp drains like a mofo) And keep my Red-Top to power the engine. Once I have my Morgan-Tec inatke installed, where will I find room to mount the Yellow Top??

Take a look at Spazz's gallery. He has dual batteries plus a whole lot of other stuff mouted up there.

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!

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! :yesy:

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.

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.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).

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.

Maybe you can find a battery in a smaller size or configuration to fit where you want it. Optima may have 1 or multiple cycle batteries that might work for you

[transio]

There are many smaller batteries designed for racing purposes that would fit easily in that spot. You can always throw the optima in the stock location and have the smaller battery just for starting power.

Thanks for all the input . . . guess I will just have to figure it out myself :-p

You should really try just using the Yellow Top and a high-output alternator before resorting to a second battery setup. Even with two batteries now, if the Red Top is getting drained a second battery will as well but just not as quick. That means your battery is picking up the demand the stock alternator can't meet. Two, three or more batteries just means you'll go a bit longer before having to recharge. Batteries are for supplying start and overload power, while your alternator recharges the battery and supplies operating power.

Optima recently released a significantly higher capacity battery YellowTop Group D75/25 in a larger case that might be easier to mount than 2 batteries.

Thanks again for all the input . . .

I have decied to go with a big Yellow Top and a Kill Switch to prevent drain when I park her for long periods of time.
