LiFePO4 Lithium Car Battery Start-Stop GROUP 48, 12.8V 60Ah 1100CCA Automotive Battery for Car, Truck with LED Display Power and Emergency Start Button

Installed without any problem. Dramatic difference in weight compared to lead-acid original battery. One click starts. Probably a way overkill in terms of cranking ability (almost twice the CCA rating). I understand that the Ah rating is effectively twice that of an equivalent rated lead-acid battery. Battery voltage remains almost constant until near full discharge. With lead-acid battery, voltage continues to drop during discharge. So the rated Ah is only partly usable because of low voltages. I have had a few of these LiFePO4 batteries in use since their introduction. The one failure I have had was in the battery management circuit. Only two were rated for high cranking amperage (as with this one), and those have been in daily drivers for 8 months, Hope this one will be just as good.

I put this group 24 in my Lexus LS400, it fit perfectly, the cranking speed is outstanding, the alternator charging 14.2 volts, amps initially was 30 amps from alternator, settled down to a little under 10 amps once the BMS learned the alternator output, after researching the high amp output from charging system. No problems at all with this last arctic blast. IF** you have a no start cold, turn on headlights high beams for 5 or so minutes THEN attempt cranking. It's counter intuitive to do that as we are used to LA batteries, lithium must warm up to get to robust large amp discharge. Current flow will warm the batteries.

I bought for my daughters 2008 VW Beetle and thought that new tech meant better! The battery build quality appeared very good and light weight. It installed easily but after driving it for a week, the car stared to have issues. The radio would turn off and restart randomly while driving and I did notice a hiccup in the car while driving. The alternator light would come on for a couple seconds and would disappear at the same time the radio comes back on. I do notice the headlights look dim while driving at night as well. The alternator is less than a year old and should have no issues. I do notice that before the battery swap, I was charging voltage was at 14.4V while on. With this new battery, the voltage charge dropped down to 13.4V while driving. After trouble shooting this with my mechanic, it came down to this battery issue. I had to replace this with the standard AGM and now the car works fine with bright headlights. It is charging back to 14.4V. I ended up return the battery. Not sure how everyone else is doing fine with theirs but my car did not like it or the battery was defective out of the box.

Initial Review: 2004 Subaru STi (group 26). Received battery yesterday at 87% charge, about 13.3V. My alternator runs about 13.8-14.0 at startup. I charged it for about half an hour while I tried to decipher the weird instructions that came with it. Ultimately just decided to swap the battery in a usual fashion. By then it was at 93% according to its own diagnostics, around 13.4V. Fits directly in without any modifications. It is feather light. Hooked it up. Car cranks a little faster than my tired lead acid battery, which was struggling to maintain 12V. Car started fine. Idles normally around 13.8V. The battery shows 100% at this point. Will have to see how this plays out over time. I drive this car rarely. Also the tires dictate no subfreezing temperatures. I have a battery tender that is capable of LiFePO4 chemistry, but I frequently forget to hook it up, so I'm hard on batteries. My garage is insulated but not climate controlled. So far I'm happy, and if this holds up, I'd never buy another lead acid battery. The weight savings are like getting 1-2 free horsepower, and it's taken from the front of the car. One more tip: get a 12V lighter USB adapter with a digital voltmeter. For like $10 I now have accurate voltmeter that matches my multimeter and has a USB-C outlet as a bonus.

Almost a drop in replacement for the dead H5 that was in my 2013 smart fortwo passion cabrio, and is working great after two weeks. So much lighter too - easier to put into the vehicle because it is so light. Exact fit - except it is not a true H5 battery because it does not have the two holes in the handle for the positive terminal cover. I drilled two holes for the cover and all is well. That said, the picture shows the holes and the battery I received did not have them. I believe that the items received should always match the pictures for the item being advertised. Oh - made in China if that matters to anyone. The stock charging system is operating perfectly with this battery - I have a Bluetooth battery monitor attached to the battery and nothing is not where it should be. Starting voltage is higher with this battery than stock, and it appears that the headlights do not show electrical load changes like the flooded battery did - I think the LiFePO4 responds quicker to load changes than the stock batteries. If any of this changes, I will update the review.

Pretty much the only reasonably priced game in town for H8 / Group 49 in lithium; we installed in Sprinter Van. So far, so good! Sometimes has coupon. Advertised as not having bluetooth for monitoring, but the TET app on my iPhone sees it! Got the TET app b/c bought this other battery for my honda: https://www.amazon.com/dp/B0FKT2Y4D8, and when my garage, the app sees both that 51R battery in the honda and this H8 battery in the Sprinter Van! YMMV as the feature is not advertised. Runs ~13.2 volts fully charged like most lithium batteries.

Perfect fit in 22 ioniq 5 original battery had dead cells in cold weather. No issues since replacing the original with this one. Nice to be able to easily check the battery with the push of a button while adding washer fluid.

Dont waste your money. Worked well for a couple of weeks, then wouldn't hold a charge, then the bottom of the battery case melted. Seller wont respond to inquiries regarding the 60 month warranty.

Awesome packaging, great product and my god is this thing light!! It’s great as my 2nd battery as the after market holder isn’t the sturdiest I find. It would probably make a great battery on its own, but I needed the extra juice when I plow. So this will be perfect!
