Fire Power HJTZ7S-FP Featherweight Lithium Battery

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.

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.

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.

5 YEAR REVIEW! Amazing battery. Several years in Phoenix heat, 2 years in N.Idaho with below freeing for temps months. It sat for another 6 months untouched and still has a full charge. I used it to start a Artic Cat Prowler 500 sxs. It didn't run great, underpowered, but let us know the other battery was bad. Best I've ever had and I've used replaced a lot.

I recommend this battery. I had to modify my bike because this battery is smaller. A 3D printed bracket to stretch the strap and we are on the 3rd season. Voltage will drop after a few weeks, I have Harbor Freight trickle charger on board with an LED that is illuminated pulling down the battery voltage after a few weeks. Jump it or trick charge for 3 hours and it starts great. No lead acid version has performed this good.

August 2021: my return window closed on april. I didn't ride that much, but I installed a battery isolator. So nothing was hooked directly inline to drain. Lithium should have a great sheriff life and the bike always started. Now not so much. 6v is where my smart charger stops it now. No more 12V. Now I have a fairly expensive battery that is junk. Dropped it to one star. The terminals do not come with bolts!!! And to make it worse, their m5 You have to drill it out and grind standard nut plates from my old battery

Fit my 2016 Yz450fx fine With use of foam provided. Super light!!! Much cheaper than other battery brand options. It’ll do the job for a few years I’m sure. Update: As of 5-25-18 battery still functions as it did new. Update: 5/04/19 still cranking strong 11/15/19- over two years now! Not one problem. Still strong crank. I have never used a tender on it. Sometimes sits for weeks at a time. I was here looking at this again to possibly buy another as a preventative measure. My bike has no kick starter. So I don’t want to be stranded. But it’s hard to spend money on something that is not broke. 10-29-20- 3 Years!!! And still going strong. I even crashed and didn’t ride for 2 months. Fired right up after getting back on the bike. Once again, I’ve never used a charger for this. I am hoping to buy a 2021 Yz450fx in a few months. So this battery will never get replaced. If not I’ll update if it dies. Nov 2020, sold the 2016 fx with battery still working great. Nov. 2022, I’m here buying a battery for my 2021 yz450f, figured I’d make a note.
