Performs well so far
This battery was installed in a V-twin with 1800cc displacement (big engine). It cranks the engine over effortlessly, better than stock lead-acid batteries. So the performance cannot be argued with.Two aspects could be improved (though still giving full 5 stars):1) While the battery size corresponds to the data provided in the listing, it is a smidgeon too thick (the smaller horizontal dimension) in real life. It is about 1/8" thicker than stock lead-acid batteries, making it harder to install in tight battery compartments. If the dimensions are not required by the internals, please size it down to match lead-acid batteries for better fitment.2) The usual pain point, the dreaded battery post nuts that like to fall out. I prefer batteries with threaded posts where you do not have to worry about the nut falling out of the post while you are sliding the battery into its place. Or while you are trying to connect the terminals. If you make the terminal out of thicker metal, you could tap it in each hole and allow nut-less connections. Though, it's not like a piece of duct tape won't do the trick, it will hold the nuts in place so that they don't fall out and either into the battery tray underneath the battery or somewhere into the abyss of electrical maze behind the battery box. LOLAll-in-all, great battery, been performing well for the past 2 months. No complaints so far, hoping it will last longer than the lead-acid counterpart it replaced. Will update review when necessary.

This Thing Actually 'Works
Soon as you get it you will be shocked. 2lbs. 13 oz is what it weighed. Put it into my 2007 Harley Fat Boy. This bike has trashed a battery every year since new. When hot it can kick back, spit, backfire or just start fine. You never know but I do know it will flat out destroy AGM batteries and flooded ones quickly. Last one lasted just 8 months and I got stuck at a fuel stop when it just would not throw that motor over hard enough.Well I was shocked when this "box of air" had the cold motor running "before it started". Wife and I took a 6 hour ride with multiple hot stops shopping all around. Couple times it fired the motor perfectly when hot. I mean FIRED it hard and fast. Couple times there was a backfire. Immediately it fired after that. Couple times it spit and coughed hot. Then immediately fired perfectly. At no time was I bummed it would not work. Building confidence in it each use.Darn thing works. Now to see if heat inside that oil tank and time have any adverse affect. Time will tell but for now, I'm riding.

dont over/under charge, no protection circuitry
I posted the dos and don'ts, they should have listed this on the product description, most notably you must disconnect battery if left for 7 days in the vehicle if you have a voltage draw ( better verify you dont) under charging for any period of time with lithium ion or lithium polymer battery's will render them dead. over charging will end up with a pile of ashes, your bike and or garage might go with itthis battery needs to include circuitry for safety isolation if over under/charge occurs (ever wonder why your phone turns off when the battery still has enough power to make a emergency call? that's under charge protection)NO battery nuts or bolts for terminal connection included!defiantly not water resistant,what can the 2 nuts and bolts possibly cost to include? makes me wonder what other corners were cut to manufacture this!If my return isn't accepted I will open the case and post the interior contents, I have flown electric r/c models for almost 15 years and have extensive history with this type of battery

Perfect battery for 07 Big Dog Mastiff
I've gone through two batteries including a Odyssey battery on my 07 Big Dog Mastiff. Had to always jump the bike no matter how long I charged it. Finally called the manufacture and they said that for the 117 ci engine I needed at least 240 cca. I checked and no other manufacture with the size I needed made one. Into I found this one. Was sceptical about the new type of battery but, it started up on the first time. Haven't had to charge it and I let the bike sit for there weeks and it started right up. Best battery I've ever had. Also the level gauge onto is a great too.

you won't believe how light it is! so far, it starts my Harley 110 SE
this is my first Lithium battery, I have a 2016 Harley Fatboy S 110 SE motor, this motor demands a strong battery, after getting stuck 3 times with the OEM POS battery, that tested out to be good, holds a charge but would only start my bike on the first attempt. OEM battery was only a yr old...I ride DAILY. I wanted to try a GEL type battery but had no luck finding one for my FatBoy. Ran across these Lithiums and decided, what the heck for the price it's worth a gamble. First off, when they say featherweight..they mean featherweight. I was VERY skeptical at first, thinking I just got ripped off, this can't work..I was wrong. As for the claims of Lithiums not requiring to be on battery tender, I disagree. I also read that lithium batteries are not fond of cold weather, I live in So Cal..so no worries there, ever! I wanted to try this battery for the CCA 380 rating. so far, its starting my power hungry Fatboy S. No longer doing superstitious acts before I hit that start button, even after 3 failed starts this battery will start my girl! OEM battery only had 1 shot to start her. I fully understand owning a 110 motor comes with its share of issues, for now, my battery/starting issue takes a back seat. But I'm still carrying jumper cables from now on! BTW..most AAA drivers won't jump a motorcycle as they are afraid of damaging the motorcycle charging system...clueless mofo's..LOL.. I will update this review after a few months to see how it holds up...If i get 2 years out it, I'm cool with that.
