Anyone using jy caps?

[2023 LTZ]

Looking to stabilize a voltage bounce. I’ve fried flooded and agm. Looked into xs but a local shop has jy. Anyone using these and have personal experience either positive or negative regarding jy performance?
Thanks

I've been very happy with my jy battery, but I likely won't buy another jy product. It irritates me they discontinued their hp40 battery immediately after the warranty expired on their first batch and now they don't offer any batteries? Also annoying that they sell products before they have them on hand; what does that say about their product testing?
