YTX7L-BS Motorcycle Battery Lithium LiFePO4 12V 4Ah 300A Powersports Battery Replaces YTX5L-BS YTZ7S-BS YTX4L-BS YTZ5S-BS for ATV, UTV, 4 wheeler, PWC, Seadoo, Polaris and Generator Battery

Great value, solid product, worked flawlessly for my 1982 Honda GL 500 SilverWing cafe build

Terrible battery, five months old and the battery died and will not take a charge. And I did use a lithium battery charger specifically for this battery. Piece of junk. I will never buy the lithium again.

REALLY GOOD IIIIGHTPRODUCT BATTERY HAD 13.4 VOLTS IN IT WHEN I GOT IT

This YTX7L-BS 12V 4Ah lithium motorcycle battery hails from Sdulibitiy (?). It's a lightweight, maintenance-free LiFePO4 powersports battery with a built-in BMS and a power display. This appears to be a nice well-made replacement battery. It's significantly lighter than a standard lead-acid battery. The power display is a useful feature for checking the voltage at a glance. It provides a strong start, but as with all batteries, time will tell how it fares with longevity. All in all, this seems to be a good, modern and lightweight power source. It's a solid choice for an upgrade. Should my experience with this battery ever lose its spark, this review will be updated.

This works great I put it in my polaris xpress 300 had for about 6 month no issues. Went all winter and started right up

never kept it's charge. total piece of junk.

Other that coming charged and bolting up perfectly, in place of the old battery, I can't say how long it will last. I've had many motorcycle batteries over the years. Some last a season, some made it 5 years. Only time will tell on this one. The one thing you should know this one weighs next the nothing. For years I've spent a lot of money to lose an ounce here or there on some of my bikes. From tires, to carbon fiber and titanium parts. Other than just losing weight myself, nothing has been cheap and more effective than this battery. On one bike, I bought a $1200 dollar exhaust that gave me a 12lbs. weight lost. That's $100 a pound. Given it also added a big horse power boost for the cost, but since then nothing was has come close to the cost per pound that this battery offers. My stock lead acid battery weighed in at 6lbs 2ozs. This one is 1lbs 14ozs. That's almost 1-1/2 pounds at the cost of a battery that I needed to replace anyway. So if you're looking for a new battery and want to save weight at the same time, look no farther.

Battery seems to be great quality but it’s not even close to being the stock size
