Its great!
It keeps my head light and dash light from dimming at all, even while running my 2 pioneer premier 12s running at 4000w. No more blown fuses either. Worth every penny.

Sound stream scx4
I was scketchy about this product at first I was thinking it wasn't gonna work but it works better than what I thought actually! It keeps my lights from dimming and I have to 12 kicker comps and a 5000 watt RE amp and it's working amazing voltage stays around 13.7 13.8 under heavy bass tones.. Overall it's a good deal

13.3 -14.1
The title/subject of this has my vlt ratings of the product, havent hit 14.4, charged it etc.. Im running the 09' Polk 5ch amp on it. To lazy to look it up but plenty of watts minus going competition, & with the stock battery on the MS3, it kept it from diming. Holds charge pretty well, Id say the spec.ratings on this product are pretty true.

Great product
I’d recommend this product because it does everything I need it to do. Led display is great although mine stays on?? Should I wire a remote wire to my power terminal on the cap?

Solid cap
All in all i am very happy with this cap, the trickle charge wire could be a bit more durable but still good
