12V LiFePO4 Automotive car Battery NEW (SD-12V6-1)

I'm a woman that doesn't know how to work on cars and it was so easy that I was able to install it. I did have to get help to get some screws out but the rest, I was able to do with no problems. Once I got it in and hooked up, my car started right up. Thank you!

Had a "problem" with my alarm system. and changed out the "spare" battery had on hand. It charges when the power is on, and is solely used as a back up battery. I don't have a load tester, amp tester, battery tester, so I can't tell you if it came charged, can't tell you if it is charging. I would have to cut my circuit breaker and see if the alarm still functioned. but not doing that - as that breaker is tied to my wi-fi, and then I have to reset the DVR and TV and other internet running items. so will wait to see in an emergency. as for that - even if the power goes out, it basically holds a charge for 2 days. I will come back to update IF/WHEN I have a real power outage. the battery was so light weight. Not sure why the size is the same as the other 2 I have. the reason I have the original, is that I am waiting to take it to a proper shop to recycle it. I read that once it loses charge, or something happens to the contacts, then the battery is worthless. the back up battery I had, actually sat around for 3 years, but that truly wasn't the issue. my neighbor found what the "problem" was to my alarm system. at that time, THIS battery was connected and still the alarm still did not come on. so the "assumption" that it would come with some charge can be ruled out. at this point, I have it installed, but can't confirm if it works. the only good news is that it has not blown up my alarm box.

Ordered this to replace the battery on my daughter’s Minnie Mouse ride on toy convertible. Had no issues in attaching it to the battery cables on the car and it worked perfectly. Had no issues with connection and no issue of it not working. Great price on this as well. Highly recommend if you’re looking for this voltage battery. Worked great and still have no complaints after a couple months of use.

Arrived with 0% SOC even after waking it up - poor QC Voltage was 10V even after applying a charge and waking it up (1.2V prior to wake up) Delivery times are not as promised, way too slow. It did eventually take a full charge to 13.33 volts, but it lost 50% of it's charge over 1 week with no use and nothing connected. Returning.

So I needed a battery for a little gokart for my kid. I needed something that will last and quick to charge. This battery came home and it was so light.. felt kinda cheap. With the low aH of the battery my go kart didn’t run for that long. Maybe an hour but this battery should be a little longer than that. Not sure if it’s really what it’s indicating it is.

I built a portable stereo from an Android head unit and a few extra parts primarily for our patio, and this battery works great for powering the system on the go. Charges quickly with a standard automotive battery charger, and powers the stereo for several hours. Would also work well in a UPS or any number of other applications. Very pleased with this battery so far.

Holds a charge and was able to turn over a 250 quad. May be a little undersized for that but I don't think by much. Biggest thing is you will need to purchase the compatible charger for this battery as a standard charger will not work and would not recommend trying one. If it lasts will be quite happy with the battery. As someone who grew up with nothing but lead acid batteries still amazes me how much they can fit in these little things now.

This battery comes in a pretty common form factor for AGM batteries. I got it because it’s nearly the exact same size as a failing battery in the UPS that runs my home server. LiFePO4 tends to last longer than lead acid batteries in these situations, so I figured it would work. But... The BMS in this battery is a blessing and a curse. It takes a lot of the guesswork out of lithium rechargeables, in that it won’t let you overcharge or over-discharge the cells inside. I didn’t crack it open to check, but I would assume the BMS also handles cell balancing, as this battery doesn’t have a way to attach an external balancer. It’s the “short circuit” protection that is a problem. I tested it with a dummy load and found that the BMS will disconnect the battery if you try to pull more than about 9 amps, which on a full charge means only 110 watts. My UPS is rated for 375VA, which is pretty dang small, but if I tried to put this battery in it, the UPS would draw too much current and the BMS would disconnect the power before my server had time to notice the outage and shut down. So that’s a no-go. They also mention it might be used for kids toys, like an electric scooter. But I can’t find any scooter that would fit a bulky battery like this, and all of the scooters I *can* find, including those for kids, claim to pull at least 200 watts. So that wouldn’t work either. Maybe it would work in one of those children’s electric powered cars, if it’s a particularly slow one. The listed capacity isn’t accurate. I discharged it at 500 mA from a full charge to the BMS cutoff and only got 4,203 mAh or 54.5 Wh. Considering it’s rated for 5,000 mAh and 64 Wh, that’s a bit of a let-down. This might be the right battery for your custom project, but just make sure you can stay within these limits.
