TPE YTX20l-BS High Performance Rechargeable Sealed AGM and Maintenance-Free Replacement Motorcycle Battery for Scooter, Kawasaki, Honda, Yamaha, ATV 12V 18Ah

For the price, you can't beat it.

Works great

It is working. This is crazy small and unbelievably light. I installed it in our quad, a 325cc. It starts right up. Push the button on the top and it shows you the voltage, ha. My concern is that it is showing 15v while charging in the quad. The documentation says to not charge it over 14.6. I hope this is ok or that the battery is able to self regulate. We'll see.

Ordered this to replace the lead acid battery in my mower, it was a drop-in replacement, even though it's significantly smaller than the battery it's replacing. It doesn't have a huge capacity, but it does have good cranking strength and starts my mower with no problems.Overall, a great small form-factor battery with high cracking potential.

For the YTX20L-BS style of this battery:After doing an initial charge with a 1 amp charger, it looks like this is *maybe* a 1 amp-hour battery, not the 10 amp-hour capacity suggested in the item title. Maybe the seller just puts the exact same Li-ion battery components in all the different style cases & calls it a day. In any case, the capacity of this battery doesn't come close to even the smallest capacity version of this battery being offered by the vendor

This battery is unbelievably light for its size. It works great, has an insane charge cycle life, and I like having the attached voltmeter. They are expensive but this is the best battery chemistry in my opinion and worth the money.

These newer technology batteries just keep getting better, smaller, and more powerful. This battery has an impressive life cycle of 2500 cycles which beats the pants off any old style lead acid battery I still have in use just waiting to get replaced. This battery is going into one of my lawn tractors in which the old AGM battery has seen the best of its days and ready for recycling. This has more cold cranking amp power than my old AGM battery in a much smaller size too. Plus this thing just looks so darn cool. It is a shame to have it under the hood where never to be seen.

This a great battery for my project that my son and I are building. These LifePo4 batteries work in a standard motorcycle or lawn tractor charging system to provide a small and very light weight footprint, while also delivering higher starting voltage to get faster and easier starter motor performance. The life of these batteries should end up being 4 or 5 times more charge cycles than the old lead acid batteries. You are getting all of the benefits with no negatives.
