YTX4L-BS Lithium Motorcycle Battery 12V 4Ah 80CCA LiFePO4 High Performance Battery Compatible With Polaris Scrambler, Sportsman 90, Honda Scooters NQ50 Spree,Kawasaki 110 Can-Am DS70,Yamaha LE

Surprised it works soo well. Installed the battery in a thumpstar TSB125e dirtbike. After fully charging it first... I was worried it would fail like the lead acid battery's in the past, bc of the bikes low charge rate... but somehow it sat all winter and still fired right up... the lead acid battery's are notorious for having low cranking power on most pitbikes.. this lipo gets the job done, time and time again...this bike also sets alot in between rides. This battery has been through deep water, crashes and sub zero weather and still no leaks, plus it shaved about 6lbs of the dry weight of the bike, it feels like an empty battery box.. For the $ spent, I couldn't ask for more. It's been solid. Sometimes we charge it up with a lipo charger just to stretch its legs... and the headlights also seem brighter a slight bit.

Item as described, dimension and size accurate, easy install; installed today in my 200 bison utv. I needed more power than what came with it for my winch which was a 12v 8ah agm? battery; i looked for months to find a 12v battery with more than 8ah in lithium and happened upon this jewel with 15ah, wow i had to try it! my main problem was i had very limited space so my options were very limited. I didn't want to put the same type and power back in if there was an viable option, and this was it. I had very linited room, but the dimensions were exactly as stated and I needed every fraction of an inch to get it to fit, and thankfully it did. So far so good, but i only managed to install it and crank it up; didn't get to try out my winch yet, so we'll see. if it doesn't do the job i'll update my review. But I feel confident with almost double the ah it will perform well.

It fits my 2005 Arctic Cat 400. 15 AH capacity was important for me as I use the winch a lot. It was installed on April 9th, 2025. If it fails too soon or does not perform as I expected, I'll edit this review and deduct the stars. I paid twice the price of an AGM battery, so I expect it to last me 10 years at least. The dimensions are very close to the AGM battery it is replacing but a little less tall. Before installation, I charged it with a lead acid battery charger at 10A setting. The battery did not have any issue during charging. The starter motor turned strong when I tried it out.

This battery if it fails it is made in China (Good luck!!!) Mine almost set my motorcycle on fire by having a Lithium ion nuclear meltdown fireworks show !!! . I had to cut the battery cable and it still wouldnt stop. had to smother it with a pair of pants ! because water only makes the fire worse! Id give it ZERO STARS!!!

Well, I messed up and will admit it. I didn't check to make sure my regulator was charging at the correct voltage and fried the battery right away. So I cut it open to see what cells they were using and what kind of battery management they had. Well, it doesn't have a battery management system which is a con but they have added capacitors which I appreciate that. Did a quick search on the cells (ITR26/7040e) and didn't find too much information or reviews on the cells but I do like that they used a bigger cell than a 18650 that commonly gets used. I'll buy another and see how long it last this time and yes I fixed the regulator and tested on another known good battery.

For perfect bike never started better! It's been a month now and no issues. Bike is an 02 gsxr-750. Any issues arise i will post.

Light and efficient battery perfect for my R12000gs, maintenance free and durable. Feeling good and safe

I was unsure this would crank my jet ski. It works great and last long. My jet ski no longer charges so I needed something that could take the abuse. This is it. I write bad reviews a lot but this is good to go.
