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.

It’s junk
Size: 9 inches
Deserves a zero. Like some others said on here, it runs for 3 seconds and just stops with battery fully charged. I got it for Christmas so too late to return. More China junk.

Great price, does a good job
Size: 9 inches
 I’m mostly old. School when it comes to yard equipment. A gas engine has got to be better than a battery . I have  a weed eater that will take out a tree but makes a lousy edger. Since I  don’t have a large lawn, I gave this guy a try. Turns out it does a pretty good job. Can’t beat the price and it’s simple to use. Be aware, this vendor sells the unit only. They have no spare parts and you will need to source replacement blades. ( they supply 1 spare). Otherwise, worth a try. John J Why did you pick this product vs others?: A cheap price and a limited need.

Not too bad for the price
Size: 9 inches
I was skeptical if an edger as cheap as this one would do the job at all. I figured if it worked at all it might be worth the price. I was surprised be it is actually pretty good. I have a medium sized area. Just one driveway and about 30 feet of sidewalk. I will use it four or five times a summer and I expect it will last for a few years. It hold a charge enough for my needs. If you have a large driveway or plan on using it every day, you will probably be disappointed. But if you have a small area to do, its not bad.
