EBL YTX4L-BS YTZ5S-BS YTX5L-BS YTZ6-BS Lithium Motorcycle Battery LiFePO4 12V 2.5Ah,150A Built in BMS Powersports Battery for ATV, UTV, Jet Ski, Snowmobile, Quad, Motor bike,Tractor, Maintenance Free

The 2.5Ah is a great battery for a 250cc.Initially I assumed it wouldn't be able to power the starter in the 250, but it has more power than necessary. If anything I'd say the 2.5Ah is powerful enough for up to a 350 or even a 400cc.The 5Ah is perfect for my CFMoto 450. It's got more power than I need to start the bike. The only reason I went with the 5Ah version instead of the 3.5Ah was fitment. The 3.5Ah was too small for the compartment. Also, the bike uses a t-box with parasitic drain. So the 5Ah works great for 30-60 days of no riding.With the 3.5Ah I would have needed to disconnect the battery during such long time no riding, or plug it in a trickle charger.

Battery doesn't hold charge and it is not proper size so in order to fit the 14 size I had to make adjustments to the battery box. This battery is junk, and I have sent a message to a supplier to provide proper solution. I will update the review after I hear back.

Perfect fit for my 2016 KTM Freeride. Works fine.Update: Cranked engine over 3-4 times then went deader than Columbus. Dropped to 2.1 vdc. Indicator on battery still showed 90% ?? Have a Lithium compatible charger but it would not take a charge. Returned for credit.

Battery is so small and light you would not think it would be enough to turn over my 6 cylinder 1500 cc Valkyrie, but it turned it over briskly. That motor will not start if the voltage is low or the starter does not spin fast enough. Nicely made, spacers worked well, and it has a charge indicator LEDs on the top, which is a useful feature for sure! Will see how it works long term in Florida as batteries and tires do not last here at all..... So far, good purchase.

Didn't quite fit in the original battery's position, but it came with foam shims and for my 2003 BMW R1150rt it works! Fantastic. Starts to bike every time. Has plenty of cranking power. Great battery for the price.

I ordered this battery for my motorcycle about a month ago, build quality feels incredibly good and its amazing how much more powerful it is while being significantly lighter than the traditional lead acid batteries. However, from the beginning mine had trouble holding voltage, and eventually crapped out fully after a few weeks. I reached out to customer support and they responded really quickly and offered a free replacement, which was shipped to me within a few days. Since then its worked perfectly, really love when companies are willing to stand by their products like this!

DOES NOT fit HD Road Glide. Terminals are reversed.Amazon filter says it fits... If your "-" terminal is on the right side of your bike, this battery will have the terminals reversed for you as well.Also, battery case is shorter than a standard battery and comes with spacers to make it fit. I could have lived with this but the terminals are a problem as it would have left the "+" terminal exposed on my bike.

Lithium battery works excellent way more starting power even has three dots to tell you how charged the battery is never let me down. I have this battery on two bikes one Aprillia RSV4 and one Suzuki GSX-R750.
