12 Volt Lithium Motorcycle Battery Powersport Battery LiFePO4 Engine Start Battery, Lightweight, High Energy Density, Long Life Cycle, with BMS YTX7L-BS

Perfect fit and maintenance free

More like 1 year and 2 weeks. It worked great the first summer. Took it out, brought it in the house and topped off the charge. We had a couple nice days up here in the rust belt. Threw the battery in, got to ride 1 day got cold for another week and hasn't held a charge since. I have multiple chargers for lipo's, liion's and most of them charge lifepo4, like this battery is. I have lipo's for quadcopters that have lasted more than 5 years. I've written a paper on charging schemes for nimh and nicad back in school. I understand how to care for batteries. These must be some serious garbage. I may end up taking it apart and seeing what's inside. If I find anything interesting, I'll report back here.

This little thing is actually legit and surprised me. I didn’t expect much out of it at all but I put it in a 700cc four wheeler that I’ve been keeping outside on the side of my house. It’s been out there since spring of ‘23 and then recently January of ‘24 on a 8 degree day in Colorado, I went out there and turned the key. Everything lit up as if the charge was completely full and it cranked right up with no problem.5/30/24 I went out there to ride the four wheeler and it cranked right up with absolutely no issues. This battery is very reliable.

Seemed great! Then after couple months very little use it only had 9.6v charged tried it work couple times then was dead. Won't take charge. 9.6v Battery is toast, Was barley used! Few months old. Just out of return window. Wasted$$$$$

I bought this for my Kohler whole house generator. It has more cranking amps than the lead acid that came with it, and is 1/3 the size and 1/10 the weight. How can you go wrong? It cranks the generator every week, and is kept on a charger, although I don't think these batteries loose voltage like a lead acid. The battery came very fast, and has been in service for several months and no problems. I would certainly buy another one.

First of all I was shocked at how light the battery was. I’m having difficulty installing it because of access under the seat on my 150 Honda scooter. One nut is stripped so I need to find one. BOTH nuts are to small of a diameter so they spin when tighting the screws. There is no acces to get to it to hold it. The nuts are also too flat. The screw doesn’t reach the nut without holding it up an 1/8” or more and like I said there’s no access. The nut bolt set up is not what you normally get with this type of battery. Normally a 5 minute job now I’ll sure I’ll be in it 2-3 hours.

always ready to start after sitting

I purchased this battery and installed it. When I tried to start my bike, it took a couple of short cranks. After the initial installation, I cranked it once, but it didn't start. I waited for a little while, tried again, and the battery was dead. I used a multimeter to measure it, and the voltage was at 3.50V, continuously dropping. I removed the battery, measured it again, and the voltage went back up to 13+ volts, allowing me to start the bike. It seemed like the capacitors in the battery only charged up for a crank if it was disconnected. Quite frustrating.
