12 volt lithium ion battery
12 volt lithium-ion battery for its size works great

Working well in the short time I've owned it.
Installed for a month or two, working well. When cold weather hits we will see how the performance is.

Battery dies instantly without notice, but so did my lead acid.
I purchased this type of battery because my LA batteries were dying without notice after only 6 months. This battery has a “fuel gauge” and will read 100% then die within minutes. The fuel gauge reads zero after dying while riding. The battery charges back to 100% in minutes. This could be my mowers or the battery. I wrote the company and they insist they will exchange the battery if it is defective but yet I have this problem and they have not replaced it. I have not tried any other Li-ion batteries for with mower to test them. I now keep the battery plugged in on a trickle charger so it can finish the entire 1.5 acres without stalling. Seems to be working.

Thank you Amazon for refunding this, but I can't imagine this battery works for anybody. No matter what I did it just COULD not hold a charge. I suspect that although the battery looks big, internally it is not anywhere near the specs it's supposed to have on paper.

Fit for Lifan Xpect
Bought this to replace the battery for my Lifan Expect 200 cc dual sport bike. Aside from the battery bracket not fitting over it, it’s been perfect. The battery bracket, in my opinion, is not really needed as the seat holds the battery securely in place. The bracket might fit if I bent it some or made some other modification, but I havnt bothered.
