I got this battery for my yamaha big bear 400 and so far it hasn't let me down, it has easy to follow instructions and is very simple to install you will have to fill it up with the supplied acid then charge it up. I charged mine overnight and in the morning I went to start my quad and it fired right up without hesitation. I HIGHLY RECOMMEND IT.

Excellent battery so far. The previous owner had an agm battery in my bike, it felt like 4-5lbs. I was looking to save some weight and I'm happy I went with the Shorai, its just over 1lb and fit perfectly. The cost isn't a factor when your getting a reliable, stronger product and saving significant weight in the process.

Delivered in two days. Fully sealed, ready to be charged. Installed next day, fired right up. Hopefully it will last longer than stock, junk battery.
