YTZ10S Lithium LiFePO4 Motorcycle Battery, 12V 5Ah, 360-400CCA, Built in BMS, Powersports Battery, for ATV, UTV, Jet Ski, Personal Watercraft, Snowmobile, Quad

It installed easily with the built-in threaded terminals, and the LED voltage indicator on top is a cool feature. It arrived at 13.0v and initially couldn't start my R1 the first time, which it's notoriously difficult to start. On the 3rd try it started, and then 2 days later it started the first time. It weighed a little under 2 lbs, which was still like half lb lighter than the old lithium (Battery Tender) battery. Let's hope it's durable during cold morning starts at the track.

Warning this battery is not a true 14.6 V battery and cannot hold a full charge. I have two dedicated smart chargers and I’m very familiar with Lipo batteries. My brand new unit that just arrived will not charge past 13.7V yes that is technically a full charge but a fresh battery should go to the full 14.6 if it is good quality brand new in the box would it not? So either the battery is defective or Old I contacted Amazon and they said they cannot send me a replacement battery unless I pay for the shipping and send the battery back package of the battery in the box that I ripped open by the way because I did not think a brand new product would be defective….. or I can print out a label and ship it back myself which I would have to buy packaging as I do not have a heavy duty cardboard box for a small 10“ x 10“ battery laying around to ship it highly flammable combustible material all I wanted was a replacement battery that would hold a proper charge. That’s it. I should not have to jump through hoops and use my money for their defect. The packaging was not damaged or anything like that. It is just a poor quality product.

Great battery for the price. Starts immediately.

This battery really supplies power at the rated voltage. Voltage does not drop like the lead acid type does. ( what I expected from a lithium battery). It has the cranking power and keeps the input voltage constant during power surges on the inverter I installed on my UTV. Lost one star because the first battery’s built in volt meter switch was broken. But 5 stars to Amazon for the quick replacement at no charge !! I don’t see the advantage of the voltmeter built in to the battery case. Most batteries are located where it won’t be visible and most battery strap down would cover the voltmeter or the switch. Kind of useless 95% of the time. I will see how it works out in the frozen north country this winter. ( I understand lithium batteries do like it below zero very much).

Easy Install is a perfect fit ,lightweight 3.3 lbs, battery came fully [email protected] volts. i believe it is a good value for the money, I recommend purchasing the charger with the battery. yahama vstar 1100 fired up quickly with ease.

Good deal and works great. Check measurements these run bigger

Do not buy this battery! I installed the battery, I cranked and road my bike for about 3 hours. The following week the battery was dead and will not take a charge. I had to give one star to write a review it was not worth the trouble to return.

This battery is amazing and the sellers customer service matches it. Ive waited to write this review to see how the battery lasted and it has outdone all other 12v batteries i own
