I have an XDiavel, but i bought a batter from Batteries+ in October 2021.
Even though the tender reported it was perfectly green, it was totally dead a couple of weeks ago. I just bought an AntiGravity from Amazon:
Buy Antigravity AT12-BS-HD Heavy Duty Lithium Motorcycle and Powersport Battery with Built-In Jump Starting 12V 8Ah, ATV, Quad UTV, Scooter, Lawn Mower, Generator Battery - Ducati, Yamaha, Kawasaki at Amazon. Customer reviews and photos may be available to help you make the right purchase decision!

I then learned Li needs special tenders. I bought a new version of the brand I already had, but it required manually switching between Li and Lead/Acid. So I returned it and got this Li specific charger. Can't realy tell you if its any good or not.
I called AntiGravity though, and they admitted their amp ratings are NOT directly comparable to CCA on regular batteries. So while my Heavy Duty version I got claims 480 amps, that's not really as much higher than the 175 CCA of my old battery.
I was really looking for more power though. The original battery always struggled to turn the engine over. Very annoying........
