Introducing the first of a new line of high discharge Car audio lithium batteries  from CROWN INDUSTY is a 56ah LifePo4 nanophosphate lithium battery with built in cell balancer. This is a ready to rock, plug n play power solution to either use as a starter battery, or as a secondary battery to supply plenty of instant power for your audio system with a quick recharge time. It is the ideal candidate to be used on vehicles with factory alternators that don't charge above 14.7v saving you the hassle of needing bigger/custom alternators if you want to run under a 5000w system.

But if you do want a bigger system you can also use multiple in parallel for more capacity. you can also use a bigger alternator on these with a max total input charge of 250a of charging per battery.

The case is constructed of strong impact ABS plastic with built in Handles with nickle coated brass terminals with m8 female threads. (Bolts are included)

Not to be used under the bonnet on petrol cars. But can be used under the bonnet on diesels. This is due to ambient temperatures.

Great no shows for people with larger feet
Size: Large, Color: (001) Black / Black / Castlerock
Some of my favorite socks!! Great quality, fit, and material. I love that they don't slip down in my shoes, especially considering I have larger feet. I also love that Under Armour offers larger sizes in their socks considering everyone in our household has much larger feet than others.

Best liner socks EVER
Size: Medium, Color: (348) Silica Green / Silica Green / Hydro Green
I have them in every color and used to get them from Sams, but they stopped selling them and I was lucky to find them on Amazon. Got all colors again. They stay, it's all I'm gonna say! And don't show in any of my tennis shoes. Absolutely love them and wear them until they get holes. They last a LONG time too. They're on the thin side and my foot loves them because they tend to get hot. There's no shrinking, they wash great with exception of the white ones I couldn't manage to keep white - they turned a bit greyish.

Great socks
Size: Medium, Color: Pink - 647
Well-made and comfortable to wear. Great for golf and other outdoor activities. Like them because they do not show above shoes.

These ACTUALLY stay put all day long - I was skeptical, but am so glad I took a chance on these
Size: Medium, Color: (014) Halo Gray / Halo Gray / Castlerock
I was so skeptical about whether these would stay on my feet all day without sliding down into my shoe - I’ve tried so many socks in the past with the silicone strip on the heel which failed. I’ve owned these for a couple months now and they have never slipped down - they stay put all day! I love the variety of colors to choose from, and the value per pack is great since six pairs come per pack (I thought it was only three when I first purchased and was pleasantly surprised by the additional pairs). They also have perfect thickness - not too warm to wear during the summer months with sneakers; I live in a tropical climate, though, so I’m not sure how they will do in cooler climates. I’ve washed each pair once or twice and the color and quality of the silicone has stayed so far (knock on wood). Overall: high recommend based on my experience so far!
