MMG YTZ12S Z12S Lithium Ion Sealed Powersports Battery 12V, 300 CCA, No Spills, Fully Charged and Activated Ready to Use (MMG4) Motorcycle Scooter ATV Snowmobile Engine Start Battery

21 Month review.I bought this battery for my 2017 Ninja 650 (size YTZ12).It is ALOT smaller and lighter than stock and comes with stick on plastic bumpers to make it fit the stock battery tray. The battery has a charge indicator in top and works well.In the 21 months I have used it there have been zero issues. I had my motorcycle shipped from Florida to Hawaii with the battery disconnected and it fired right up after a 3 month wait.My 2015 Harley 883 with a traditional battery didnt do so well, but I was able to use this one to jump it with no issues.I will be buying more of these as my other 4 bikes batteries die out.

Perfect for my Proto Type 371, purchased this Battery for another project, I've taken a pair of Bang&Olufsen Beoplay S-3 Bluetooth Speakers at 100 to 240 Volts at 20 watts power Consumption each and used a 300 watt true wave 110 volt power inverter to power the B&O's to make them totally portable. At $399.95 retail each, I paid a fraction of retail by finding this pair on Letgo. These B&O's sound amazing and now they are totally portable with this Battery, I'm still in the process of seeing how long they will run at 3/4 volume, I may have to purchase another one, possibly for longer play time, so far so good. I will update as soon as I see if I'll have to use two of these Batteries. So far I recommend this Battery, for the light weight and longer running time, compared to the led acid Batteries. I will definitely be back with updated review and photos of the device, my Proto type 371, once I cut the holes for the Speakers and install the custom grills, in this custom portable Bluetooth Speaker System. Yes it will be for sale once completed.

Very light, compact. They come with the sizing legs to help fulfill the size requirements of the bikes oe battery. Used it on my rc51, she cranks stronger and can stay off tender for up to a month, she still cranks right up. I'm going to put this in all of my bikes now.

I bought this battery as part of my lightening project. It reduced the weight of my KLX300SM by 4 pounds, making the curb weight 288 pounds including an oversized 2.7 gallon fuel tank full of gas and a 3 pound steel rear rack. Even though the battery only weighs a pound, it's strong enough to turn over the engine easily. It works fine and I'm totally satisfied with it.

At first I was pleased with the weight savings from my AGM battery to this lightweight lithium. Excited to have this battery last for what I was hoping to be far longer than a stock OEM battery... my bike fired right up and performance was fine for the first month. THEN IT GOT COLD, bike sputters and lights flicker, low cranking amps... bike won't start. my 5 year old AGM battery that was sitting on the shelf fired up the bike, but this new lithium piece of crap wouldn't!I've charged it for 24 hours, and still not enough power to start a cold motorcycle. Very disappointing and I'm past the return date, this is why you don't buy cheap batteries folks... you've been warned!

I needed a modern and more efficient replacement for the factory AGM HD battery used in my Buell XB12S. Not only does it crank and start the motor quicker and easier than the factory battery but it’s also smaller and weighs only about 1.5lbs. It’s crazy how much better these modern batteries are. Price is also very competitive compared to other Lithium batteries on the market.

Installed in a 2015 Honda NC -700,wasn’t easy,I had absolutely no slack from the cables,had to slip a ring terminal for a smart charger into the equation,getting the nut to not fall was impossible,made a shim with a matchbook cover to hold nut in place,bango it worked. As far as performance,don’t know,do know I got 7 years outta that factory Yuasa. DC

Easy to install on my Super Tenere & very light weight. Bike fired right up after installing. Haven't had it that long in the bike so can't comment on longevity yet.
