I lost over 25 lbs in less than an hour...
 

And I didn't even work up a sweat... lol Had to slightly modify the positive terminal, or it would have taken abt 15 mins.

I just kept the stock tray & OEM tie-down for now. Saved 25.5 lbs.

These lithium batts are serious. I had this in my GT-R, so plenty of cranking power for the FR-S.

The Brand / model and price please?

looking into doing this on my car where did you get the battery and how much, also what modification was needed for the terminal?

No charging system changes? Just a "direct" bolt in?? If you have to charge it, is there a different charger? Curious.

I also everyone above lives in warm climate... How bout cold climate?

googled "L680 lithium battery" and came up with this:

http://www.summitracing.com/parts/lpp-l680

yikes, $899.

Good Modification for the money compare to a normal battery but it's expensive when your OEM battery is brand new, maybe a good choice when you need to replace the OEM battery when she's dead.

You can lose more, maybe up to 50lbs with this model : http://www.odysseybatteries.com/battery/pc680series.htm

150$ for the PCM680

Title made me think this was spam :lol:

the stock battery weighs 29.6 lbs

SUPER B WEIGHS 3.9 lbs

That battery is near to a grand last I checked

In case anyone was wondering what the weight was on the stock OEM battery, they are 29.6 lbs.

EDIT: Nevermind, somebody beat me to it. lol

50 lbs? The stock batt is just under 30 lbs.

Here's the weight.

Also, these batts LAST...

I have a Shorai Lithium battery that I used this year in my Miata for autocrossing that I'm thinking about trying in my BRZ next year. Only weighs 24 oz and cost less than $150

Came for pics of rolled over 86.

Where are they

He handed me that battery last night and I nearly shit and how light it was.

I want one but that price... it wont be the single most expensive mod on my car for the foreseeable future hahah
