This is an excellent little battery! I replaced my Genuine Buddy's stock Lead-Acid with this, it just wouldn't hold a charge and kept leaving me with low-voltage gremlins. This unit dropped right into the bay. I didn't realize there's more space in there, I thought I should have maybe gone a size larger. No need - it runs like a stone cold champ. It must have a decent BMS, since it took a charge from my non-pulsing LIDL charger very easily. The voltage display is a nice touch, since it isn't like I have a meter I carry around with me. It holds a charge for weeks at a time with no appreciable drop. I just turn it on and press the button. Can't beat the price, either. It was the same money as another lead-acid, but weighs less and works better. I'm very happy with the purchase.

I did a little research and came up with this. I wanted a lithium battery for the gen 1 klr 650. The battery i replaced did sit with the positive on the left and negative on the right. For the TYKOOL battery to sit with the posts facing rear needs to have the pos and neg flopped. The Factory terminal leads should be long enough. Mine were and it fired up like with authority out of the box. This TYKOOL battery has a readout on the top as well which i find pretty awesome. All in all, it took a few minutes and she's good. This battery is significantly lighter as well for those weight savers out there. Had an agm duralast in it which is a good battery too, but she was worn out. Would turn her over 2 times very weakly, then make the "i need more power whine". Happy Trails!

A warning. Thus battery has a battery control module or BCM which stops the batteryfromchargingonce it reaches a certain voltage. I installed it on a 2016 BMW GS which has a shunt style regulator like most bikes. Within 1 mile my voltage was spiking to 18v and the electronics were entering safe mode. The BCM stops receiving current but the bike is still generating current and a shunt regulator doesn't know what to do with the extra V. A 'series' style regulator will adjust the stator to reduce output. Know what kind of regulator you have before using this battery.

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

This battery, like most on Amazon, seems to have mixed reviews. I purchased this for my Gy6 scooter. I have it mounted, laying on its side under the seat. It’s working great so far. Taking a charge nicely. Starting up great. It’s also quite a bit lighter than the old battery.

Lithium batteries are the best thing that has come out in a long time in technology for batteries. Whatever you put them in motorcycle , side by side it will turn over quicker start faster and the best part about them is you don’t. Have to use a battery tender with them my Harley sat for 2 months and fired right up when I went to start it . So I now have them in all my toys 3 motorcycles a side by side and all my friends are using them now to. if you want a battery that’s going to work by one I promise you won’t be disappointed at all

This thing is great! I put it on a 150 cc GY6 go kart. I am getting extremely tired of dealing with lead acid batteries! My first experience with a lifepo4 starter battery was for my zero turn. I absolutely love it, so I figured for only $24 dollars more than I can get an equivalent lead acid battery for, I can’t go wrong. The only reason for the four star review was because I don’t know how long it will last. There are several reviews saying it will not last or it was bad from the get-go. I just haven’t had that experience yet. So time will tell! Like another reviewer said, I did keep it in the foam packing that it arrived in just so it would fit my old battery slot snuggly. It is quite a bit smaller than the battery it replaced. Also, as stated in another review, make sure you have the polarities correct. They are opposite on this battery as compared to my lead acid batteries. The lifepo4 battery I purchased from my zero turn is the same way, so maybe this is just normal for lifepo4 batteries.

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!
