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 was skeptical upon arrival. This battery seemed to weigh less than 4 D-cell batteries. I installed it into my Predator 3500 and it started my generator flawlessly. I was truly amazed. The next test is longevity.

I perchased the battery to work on my vintage Harey. It charged up fine but due to weather conditions, I was unablle to ride it till now. The battery went dead while riding it ten miles. It does not charge on this bike but it did not state what type of bike it would work on. Now it is too late to return it. I now have a battery that I don't need. Just make sure you know what lithium batteries work on before purchaing it.

Bought it for my Honda Pioneer 700. Perfect fit and good starting power.

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

wow what a difference in the weight, great quality

Perfect fit. Don't go by the numbers on the screen for voltage. Out of the box it will show 13.1 volts but quickly shuts off. I thought it was a defect but it shuts itself off so no worries..

Fit perfect on my 2023 KTM 890 Adventure R , will test it out at COBDR next week

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

Best battery tested so far, will buy again

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.

Lo compre por que se que salen muy buenas estas baterias pero no me duro ni 3 meses
