LFP9-BS-STD [+ -] Lithium Powersports Battery 240CCA 4Ah Digital Volt Readout IP66 for Ninja 400 Z650 Honda CBR600F4i KTM Duke 390 Suzuki GSX-R600 GSXR750 Predator 500 Replaces YTX9-BS

Installed this in my 1994 Harley Dyna Convertible 1340cc, 32 amp charging system. Really happy with this purchase! My year and model motorcycle has a unique battery box that only allows a battery of 6-7/8 inches in length to fit. Some batteries are a little longer and will not fit. Even a fraction longer will not work. This one fits exactly! I was going to use the next size smaller battery #TYKOOL YTX14L-BS, but decided to contact the company to double check. They suggested the YTX20L-BS-STD was "more suitable for my application" and informed me that the battery should fit and it does! No room to spare but it fits!! This battery is replacing a non-BMS lithium battery that I have used for the past 4-5 years, and I am impressed with the quality and construction. Nice thick plastic case, solidly mounted posts that are integrated into the case, and stainless hardware. Install was simple and easy. Battery arrived fully charged but I put a charge on it before install and it really did not need it. The lithium charge cycle only took about 10 minutes. I like the feature of the digital voltage display on the top of the battery as it works well and the read out matches my meter. The bike fired right up. The 480 cranking amps really turns the engine over with zero effort. After it starts, the battery is recharged in the first 5-6 minutes of running. Really impressed with this battery! Happy with the battery fitment and function. The install was easy, and the companies customer service provided me with all the information I requested/needed to make sure I got the right battery for my application. Highly recommend!

Had a completely dead battery in my 2001 Harley Electra Glide. Never bought lithium before. This fit perfectly in the battery cradle. Bike starts strong now. It worked great for me!

Get battery so far. Much lighter than the OEM battery and fit my 2022 Road King Special perfectly. Has more than enough cranking power. Shipped fast and is cheaper then the heavy lead acid OEM battery from Harley.

Don't really like to write bad reviews but since there was only five when I originally bought this battery I figured I would add mine. When I first received battery as others have already noted the lightweight surprised me I figured if it works correctly and get twice as long then a normal lead acid or AGM I was fine with it but it was really just feather weight which surprised me. Battery was fully charged and seem to work fine for the first two weeks then last time I checked it it was at 86% then did not start the bike for 2 days and then just went completely dead and would not take a charge. Had to fight with Amazon a little bit as far as to get a full refund since it was 2 days past the 30 day. Still have not received the refund seems to be taking an exorbitant amount of time and I think I've only sent two things back in the Last 5 Years of ordering many items from Amazon. Hopefully if you already have this battery or planning on getting it you have better results than mine but I can only review my own experience and with my experience this battery was Zero Stars.

Fast shipping, perfect fit and works great!

It is way lighter than a lead battery

This worked great in my Predator 3500. Although a little more expensive. It’s worth the extra money.

Awesome battery and change my whole system is more powerful I love it

Installée sur Skidoo Expedition SWT 900 Ace turbo 2021. Elle est de bonne dimension et répond à nos attentes. Aucun problème de démarrage après 1 semaine d’utilisation par température moyenne -20 celsius.

First time buying a lithium battery. Super impressed with it. The digital readout is an awesome and valuable bonus!

no pesa , llegue a pensar que seria muy chafa, y me sorprendió la calidad y las nuevas tecnologías. eres el típico que saca la moto cada tres o cuatro meses?.....esta cosa es tu solución

Great battery. Has a battery charge state indicator on the top showing the exact voltage. It shuts down when the battery is low to protect it from being discharged too deeply.

Worked well for three months then died. It won't even take a charge.
