At 52lbs of weight savings, that's not such a bad cost/lb ration compared to the other stuff people do to lose weight, but still nutty expensive unless you're competing with the car or just doing it for fun
I just looked this up and its the VPR-S40. At $1,660 its not bad for the weight you are losing, when compared to high priced cat back exhaust systems, which shed much less weight for the money.
Model Number: VPR-S40
Nominal voltage: 12.8 volts
Cranking Amps (CA): 1270 amps
Cold Cranking Amps (CCA): 780 amps
Capacity: 49 Ah
Reserve Capacity (RC): 63 minutes
terminal type: SAE post (requires adapter), M6 male, M6 female
working temperature: -22°F to 140°F (max 170°F)
dimensions: 9.75x3.75x7.75" (not including terminals)
weight: 9.5 pounds
I should also add, these batteries carry a 2 year warranty. If its not up to snuff, one could always argue with Voltphreaks about a replacement.
