Note that you cannot compare CCA ratings between lead-acid batteries vs. lithium. Lead-acid batteries use 7.2v reference for amperage measurement. So you hook up large drain/load on battery and adjust until voltage-drop is down to 7.2v. Lithium won't drop that low without permanent damage, so their ratings are done at lower-load for less voltage-drop and CCA doesn't compare directly. Most bikes will suck only 60-90amps max when cranking, so you can't "force" more through. As long as battery meets that minimum amount for your bike, it will work just fine.
Most likely failed lithium has nothing to do with CCA. It's lack of over-discharge protection. I've confirmed with Antigravity that they do not have over-discharge protection. Which is circuit that disconnects battery when voltage drops below certain level.
I bought another brand that was very inexpensive to test out lithium battery. Got small 4-cell unit (-9lbs over stock) that started up my race-bike just fine for 3-years. Then I made mistake of moving it to my street-bike. One day without thinking, I turned off bike (but left lights on) and ran down driveway to get mail. Talked to neighbor for 5-10 minutes. Came back and found lights off. Battery was drained and dead! Cells destroyed permanently from over-discharge, kaput!
So whichever battery has over-discharge circuit is better because it will allow battery to be operational for many more years. I haven't checked with Shorai to see if they have this feature. But will now before buying another lithium battery. It's cheapskate profiteering really, only costs an extra $1 to add that feature.
