Fire Power HJTZ7S-FP Featherweight Lithium Battery

I switched from a lead acid battery on my 2013 Yamaha FZ1 to a full-size lithium battery 5 years ago. The difference in weight was astounding. I moved across the country and did not ride for 3 years so the lithium battery died and I could not recharge it. I went online to find another battery and saw this one at a super low price, it had good ratings so I went for it. When it arrived I thought it was a joke,​ the battery is so tiny and light I thought there's no way this could work! I installed it and the bike fired up instantly, with amazing cranking amps. I keep it plugged into a battery tender now I was just off it for a month and got back on,​ it fired right up with no problem. You won't believe how small, light, and how strong it is. ​Don't hesitate, buy this one now​

Works for my Yamaha XT225. It's lighter than the regular lead-acid battery. Also smaller but comes supplied with some self-adhesive foam pads to bring it up to the same height as the original battery. With some custom work, I could probably use the free space for storing some small spares/tools. More expensive than the lead battery, but I like it for the decreased size/weight. I also hope that it lasts longer than the typical lead battery which seems to die if anybody looks at it funny. Update: (2019/6/27) a couple of years later and I'm loving it. Maintains a charge over a long period of time, like at least 8 months (enough to flatten a lead-acid batter, sometimes permanently), cranks fast. A good upgrade for any motorcycle and a no-brainer for any kind of off-road or dual-sport when saving weight is key.

Great battery. Cut a few pounds of weight off of my bike AND the battery doesn't drain down over time like my old lead-acid did (and every lead-acid does as a result of the chemistry). It has a little battery gauge built into it, not sure how well that works but it's a nice idea. I'd never go back to lead-acid for a sumo, dualsport, or mx bike again. Edit: 4 years later and this battery still works great. I did leave it in a bike for about 9 months without charging or running the bike and the minor parasitic drain (likely in the bike electrical system) took it down enough that the bike wouldn't quite start, but I put it on a cheapo 12v 1a charger for 20 minutes and it started right up. Bike alternator charged it up the rest of the way and it's been going strong for another 2 years since then.

These batteries are Great , very very light , very well made ( sealed ) and very high. power output and very little power loss during periods of storage. I have two small 250cc motorcycles on my ranch and after I bought this battery for one of the bikes as a ‘test’ , I went ahead a bought another for the other bike just to get rid of its old heavy , wet lead acid battery . So far , I am very happy with the two batteries I have. They even have a small LED strip of 4 small blue lights and you can press the small button on the strip and it will tell you what charge state the battery has . ( 25% 50% 75% & 100% )

So far I really like this battery. Much less expensive that the Shorai I had in the bike previously which self-destructed just out of warranty, and so far has performed very well. The little charge level indicator is a great feature as well. Very useful. I think it's lighter than the Shorai as well.

I'm very very annoyed with this product. The battery you send me is not the battery that appear in the picture. It mean that this battery don't work for me cause I have a Husqvarna fc450 2016 and it don't enter in the battery slot. I I don't say the battery is bad because I try it and works very very good. The thing it's that is not the product I want to buy. It's like you wanna buy an iPhone 6 and the company send you a 6 plus. I live in Uruguay, so the unique thing I going to win its alert customers what they are going to boy. Sad it's my state.

The lithium ion battery is much lighter than my stock lead acid battery that was stock in my KTM 300xc dirt bike. It has plenty of power to start the bike, the only drawback is cold weather. You need to try starting, let the battery “warm up” and retry a minute later. This is the technology with lithium ion batteries, not a fault of this item. Lasted 3.5 years and now my bike won’t start, measured less than 13v now, it was 13.5v new. I’ll probably try another one to see if lasts longer.

Great battery! Expensive. But compared to other lithium battery it is a bargain. I put this super small and lite battery under my cafe seat. I even used it in my enviro management class to show just how far technology has come. It is working great on my CX500. Cranks right up. Is recharging with the 1981 technology on my bike. I did not make any mods to my honda cx500 charging system. I have put 91 miles on it plus lots idle time. I discharged it while troubleshooting and installing my lights, then tried to charge it with my very old deep cycle charger. It would only half charge and I was worried it would damage the battery. So I went and bought the "battery tender plus" for lithium batteries from walmart. Wow! It fully charged in like 8 minutes! See my pix and listen to it crank. I would but again.
