TYKOOL 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

Amazing the power from such a light little battery. Cranks my 2003 HD Ultra Classic with ease. Hopefully this battery has longevity also.

Fit my bike height wise but was a bit long width wise to the point the battery bracket was unusable. Left it in as it is snug and shouldn't move any ways and bike started right up. About 70% lighter than stock battery

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!

First battery I received ended up being defective. The replacement works perfectly. The 5 stars are for the customer service from the manufacturer. After a couple emails, a replacement was sent quickly. Very pleased!

Great battery works good for my application. Use it to put in my Honda pioneer 1000. It is a little long but still works just fine. It is super light and easy to install. I’ll give this product if five star. It is well worth the money and works right been using it for a couple months now no issues. Highly recommended.

Very light weight, easy to install. It also comes fully charged. Since it is a lithium battery, pretty much no prep work needed. I was able to install it within a few minutes after taking out the old one. Fits perfectly on a 2018 KTM 390 Duke.

Works great!

1/3 weight of lead acid or AGM, should last 3 times longer. Didn't last 30 days, took nearly 2 weeks to get a refund.

Iv bought about half a dozen of these tycool batteries in various sizes and have been extremely pleased. The weight difference is very significant and the increased static voltage compared to lead acid , makes my power equipment start up better than before

Fits my Vulcan 900 custom perfectly, light and the volts reader works great, started first click

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.

Works great on my TRX450S fits great
