In prjkt EVO VIII MAYHEM, the stock battery was changed out for an Odyssey PC680 small battery and STM Billet Battery Tray last year. All I can say is that this small battery packs a lot of power. I like it so much that I chose to get the same battery and tray from my supplier for all my go-fast/performance stuff- Street Tuned Motorsports in Avon, NY, for prjkt 240SX MAYHEM.
The PC680 specs are:
|Pulse (5-second) Hot Cranking Amps (PHCA)||520|
|Cold Cranking Amps (CCA)||170|
|20Hr Nominal Capacity (Ah)||16|
|Reserve Capacity Minutes||24|
|Dimensions L x W x H (in)||7.15 x 3.00 x 6.65|
|Metric Dimensions L x W x H (mm)||181.5 x 76.3 x 167.8|
– 680 cranking amps for 5 seconds
– 595 cranking amps for 10 seconds
– 525 cranking amps for 20 seconds
Stock battery weighs around 37 pounds, and the PC680 weighs only 15.4 pounds. With rugged construction and packed tightly with pure lead plates, the non-spillable AGM design ODYSSEY battery protects against the shock and vibration that can quickly destroy other batteries. And the pure lead plates mean more power—twice the overall power and three times the life of conventional batteries—up to 400 cycles at 80% depth of discharge!
The STM Billet Battery Tray is just a beautiful, functional piece that securely holds the battery in place regardless of how dramatic things get when putting the car through the paces.
The beauty of this system is that it can be mounted anywhere in the car and is compact enough that you won’t even notice it.
