MMG Lithium Ion Motorcycle Battery YTX12-BS Sealed Factory Activated, Compatible with Kawasaki Suzuki Triumph Yamaha (MMG5)

This battery has been working great and has had no problems yet. I had to shim out the area so that the battery would sit properly, but this is a lot cheaper than the battery that actually fit and was lithium ion. Would buy again.

IVE purchased 2 of these in the last 2 years and neither of them lasted more than 500 miles,BOTH OF THEM,they are kept on trickle,i live in California so its not exposed to severe cold only hot,Lithium may be lighter but for me ill never go that route ever again considering they cost as much as a car batt yet they are a 6th of the size its a scam abd should be avoided especially this brand

This thing is SMALL and LIGHT but does the trick, Just what I needed for my weight-sensitive scooter needs.

My friends had replaced their AGM lead acid batteries with Lithium Iron so when my motorcycle battery failed I thought I would do the same . I saw this battery and costing not much more than an AGM battery I ordered it. I then heard about Lithium Ion batteries catching fire and started to do some research all of which made me very nervous about my purchase. I contacted the supplier with some of the questions I could have asked before ordering a Lithium Ion battery . I have included their reply (which didn't instill any more confidence in my purchase) .I eventually decided to try the battery and installed it in my motorcycle. Installation is relatively simple with the bolts supplied. Being much smaller it did not fit the mounting clamp and it did not come with any spacer to make it the same size as the original battery. I used some high density packing foam to take up the space, With 1 months use now I have had no problems to date.It has started first time every time.I have not used a battery tender and have gone for up to a week without riding. I live in Southern California so cold temperature starting is not a problem I am likely to face. If it doesn't catch fire, I will be happy, if it lasts more than 5 years I will be extremely happy.The suppliers response to my questions1.Does the battery have an internal BMS( battery management system) to balance the cells?- No as far as we know.2. Do I need an external charger / battery tender with a BMS like Shorai?- if the vehicle the battery is installed has no current draw the battery should be OK for up to 6 months, if it does has a constant current draw we recommend to disconnect the battery or install a master switch.3. If I leave the key on ,Does the battery have internal protection against becoming too flat to recharge -i.e. low voltage shut off or similar?- No as far as we know.4. Does the battery have internal short circuit protection to protect from thermal runaway?- No as far as we know.5. Two reviews on a similar battery indicated that the battery caught fire !! is this a possibility ? what do you attribute this to and what can I do to prevent this happening?- As far as we know lithium iron batteries will not caught on fire as stated by the factory, they can in extreme conditions like faulty voltage regulators/extreme heat and or current draw overheat melt the battery case. But only lithium cobalt batteries should be susceptible to fire in extreme conditions.6. I have the NOCO genius battery tender G1100 will this be suitable to leave connected with the lithium mode selected?- lithium batteries work in a different way than acid batteries , is always better to disconnect the battery if you know the vehicle is not going to be used for a long time and you currently know your bike has a draw. Regardless of the brand of the charger as factory suggested is always better to disconnect one of the battery cables, its free and you will have peace of mind that is the best way to treat your battery to last for along time.

Solid battery, small & light weight. Use these on several motorcycles.

Battery will no longer hold a charge.

A short summary: Battery is a good half-inch wider than standard YTX12-BS, and half the height. Huge issue fitting it into my old Suzuki LT230E-H stock battery holder. Included spacers are pretty useless, it's too wide for the holder, and way too short.I've had the battery for a short enough time that I can't say much about its long-term use. These Lithium batteries seem to be significantly shorter than regular ones, and the included pads are basically useless as far as getting it into the same position as the old one. I used several different tools and searches including checking my old battery to make sure I got the replacement size I was supposed to, and this battery is maybe half as tall as the old one, and way too wide.A normal lead-acid battery fits nicely with a bit of space for protective padding in the holder that's on my ATV. It's the stock holder, and hasn't been bent or anything. This battery won't fit into the compartment without either cutting the sides off of it, or bending out the compartment, and this is after removing the padding that was in the compartment.Additionally, since the battery is so short, the stock battery cables won't reach the terminals if I was to set it inside the compartment at the bottom. The 3 foam pads the battery comes with are pathetically small, each about 1/4 of an inch thick and 2 inches by 1 inch in length and width.Even if I stack them all up, it doesn't make up for the about 3 inches lost over a regular battery. I would rather they made the case the appropriate size, even if it meant leaving some empty space in it or having just an extra chunk of plastic glued to the bottom. That would make up for the lost height, but it still doesn't make up for the fact that the battery is just too wide. The compartment I have to work with doesn't really have space, it's a metal holder that doesn't have much around it, so I may be able to bend it out enough to fit the battery, but the fact that the battery is so overly short and excessively wide isn't helping anyone.

I must admit. I had my doubts about a smaller Lithium iON battery to power my motorcycle. But those doubts were clearly unfounded. Once installed, it works fantastically. I don't know about longevity yet. But I'm really happy with the purchase. I certainly recommend this battery.Why not 5 stars? The design of the terminal slots for the nuts is flawed. If you don't balance the battery continuously, the nut will simply slide off the battery and into the bowls of your bike, never to be seen again. This happened to me. Given that the size of these bolts/nuts are not standard, I couldn't find a replacement from ANY of the major hardware chains. I had to order replacement nuts/bolts online.1) There should be slots at the bottom of the terminals to keep the bolts from just sliding right out as you are trying to attach the battery.2) There should be AT LEAST one extra nut and bolt included with the battery.
