KEMIMOTO Lithium Motorcycle Battery YTX5L-BS/YTX4L-BS, LiFePO4 Lithium Battery 12v 2.5Ah, Pre-Charged Powersports Battery, with 2 Universal-Fit EVA Spacers, Compatible with Motorcycle ATV Jet Ski

Package was so light I thought I was scammed. This battery i9s incredible light, but works great. have had one in my H2 SX for about 18 months with zero issues. Holds a charge really well even if the bike sits for extended periods of time. Highly recommend!

I purchased this battery after replacing the battery in my CRF250X with a lithium 2 years ago. The prior lead acid battery would lose charge quickly after attempting to start the engine more than 2-3 times (ethanol gum building up). The combination of adding a high quality fuel stabilizer, a JD jetting kit and adding the Lithium battery replacement has eliminated starting issues with the bike. I purchased this unit for my son's TRX400 to solve the same issues. Love the light weight. Just be sure to get a Lithium Ion compatible trickle charger for these units when in storage to avoid problems.

This battery fit perfectly and the fact that it is lithium and that it is lighter along with be able to go longer between charges if not used makes this a perfect cold weather motorcycle battery. I've had it for over a year and am loving it. Definitely recommend.

So far so good. I put it in a 2010 Ducati Multistrada S & it cranks it over with no issues. I also like the double posts. It makes attaching the positive & negative cables very easy

2 years and still going strong! I own a Yamaha Tenere 700 and MT10 that were due for some battery replacements a couple of years ago due to storage and lack of use. I chose the 12v 6Ah Kemi as the replacement for the ol led acid bricks. I was skeptical of the quality of lithium batteries from MULTIPLE horror stories I've read online. To my surprise these things hold up and help start the bikes WAY better than oem. Yamaha is not known for the easiest bikes to start, i can attest to this as my mt10 took forever to crank up, not anymore! The cold cranking amps on these batteries are a godsend as it is almost an instant fire up on the bike now compared to the old led boat anchor. I do track my mt10 on occasion so the lighter battery is also a major plus in my book. ONE thing to note, if you do decide to buy a battery tender (I haven't needed one since purchase btw) make sure its lithium compatible as the charge voltage will not be correct for these batteries. One more thing to note, these batteries will need to warm up in winter, click your bike on (do not crank) and let sit for about 1 minute, turn the bike off then crank it over. This is an excellent product that has held up in EXTREME heat and sub freezing temps for over 2 years!
