Well, for some real power and cut weight, you can go with some EarthX Lithium Iron, or the one I got, the Shorai.
The cost is not going to be $60. More like $360. But they should last several years longer, have no sulfation issues, and do 540 CCA (my Shorai, anyway). And they weigh a fifth of the stock. And work very well in the cold (you get multiple attempts and they improve on every hit as they warm up, instead of dying on attempt one like lead-acid).
But the price is certainly "enthusiast level" especially as the Rockets need the biggest they've got.
Very happy with mine though, going strong for several years already.
