Surprised it works in a pitbike .
Surprised it works soo well. Installed the battery in a thumpstar TSB125e dirtbike. After fully charging it first... I was worried it would fail like the lead acid battery's in the past, bc of the bikes low charge rate... but somehow it sat all winter and still fired right up... the lead acid battery's are notorious for having low cranking power on most pitbikes.. this lipo gets the job done, time and time again...this bike also sets alot in between rides. This battery has been through deep water, crashes and sub zero weather and still no leaks, plus it shaved about 6lbs of the dry weight of the bike, it feels like an empty battery box.. For the $ spent, I couldn't ask for more. It's been solid. Sometimes we charge it up with a lipo charger just to stretch its legs... and the headlights also seem brighter a slight bit.

Battery never held a charge out of the box
Battery didn’t last 3 months. I followed all instructions to charge and it was still weak out of the box. I had it I. A small 110 atv. Only started it like maybe 15 times. Now I have a useless lithium battery that I actually paid more for based on the lithium battery advertised on Amazon.

Inside the battery
Well, I messed up and will admit it. I didn't check to make sure my regulator was charging at the correct voltage and fried the battery right away. So I cut it open to see what cells they were using and what kind of battery management they had. Well, it doesn't have a battery management system which is a con but they have added capacitors which I appreciate that. Did a quick search on the cells (ITR26/7040e) and didn't find too much information or reviews on the cells but I do like that they used a bigger cell than a 18650 that commonly gets used. I'll buy another and see how long it last this time and yes I fixed the regulator and tested on another known good battery.

Battery what?
This battery in no way can be used for a mower. It's so small it looks like a toy! Very bad buy, be careful to read dimensions, or be prepared to use it for a Tonka toy truck!!🤔

Good little LI battery
It was able to run the starter in my KLR, which is amazing considering the size and weight of this battery! Not sure about the depth of discharge yet, but otherwise I’m really happy.

It’s aight
I don’t see at this point in time how this outperforms a lead/acid, sealed, maintanence-free cheapo battery. Maybe a tad lighter but otherwise , doesn’t crank harder or outlast the old one I just took out that’s been in my ch80 for 2 yrs
