Description

LiFeP04 batteries are maintenance-free batteries, If you need them all the time, Then lead-acid becomes too unreliable and laborious, The battery's lithium-ion properties reduce the weight of traditional lead-acid batteries to less than half, While significantly improving performance and capacity, Traditional lead-acid batteries contain large amounts of lead, After disposal if not properly disposed of, Will pollute the environment, While lithium materials without any toxic or hazardous substances, Recognized by the world as a green battery, Its great durability allows you to easily use them at home and at work, Or safe outdoor needs , The environment is most important. Recommend using a professional LiFePO4 charger to charge the battery so that it can be charged to its full capacity (existing lead-acid battery chargers (wet, AGM or gel) will also work fine) Lithium ion batteries can be discharged up to 100% without causing damage. Make sure to charge the battery immediately after discharge. We recommend limiting the discharge to 80-90% depth of discharge (DOD) to avoid disconnection of the battery by the BMS. 12V LiFePO4 battery have no liquid inside. This allows you to safely mount the battery where you want to place it. Please note! Our battery is not a starter battery, it can't be applied to motorcycle, go-kart, generator, lawn mower, trolling motor, jump starter, UPS above 750VA/450W, scooter above 24V 200W, etc. The working current of our 8Ah battery is 8A, the maximum can't be more than 10A, because the current is longer than the battery's working current for a long time will damage the battery.

    • Very light weight batteries
Size: 12V 7Ah-2PACK
I like the fact that they came in a matching pair. There are so many things you can use these for. You can build your own solar power generator for charging things. Or powering lights when your power goes out. I am using one of these to power two 12V under the cabinet LED lights in the kitchen and one of the same in the shed. Easily recharged with a 12v battery charger with alligator clips. I found these to be an excellent buy and recommend them. ... show more

    • What an improvement for my UPS!
Size: 12V 7Ah-2PACK
Holy mackerel I should have done this upgrade a lot sooner. My 6 y/o APC Back-UPS XS 1000 uses (2) 12V / 7Ah sealed lead-acid (aka SLA) batteries which can manage all of about 10 minutes of run time for the 125W it takes to power my internet modem, wifi router and desktop computer... and that's only when they are brand new; after about a year that run time drops to 6 minutes or so, and after 2 years all bets are off whether the UPS will even keep the power on during a 5 second interruption. Once I slotted in these LiFePO4 batteries and ran the self-test to recalibrate the estimated run time it reported I had about 40 minutes! So, 4x the run time and way more expected cycle life than the UPS is likely to survive for about twice the cost of the awful SLA batteries. BTW - it looks like the 10Ah version is the same size as these 7Ah, so would be an even better choice. Also note that the discharge current is limited by an internal BMS to about 10A, so in a UPS application each one is good for about 120W max load (ie - 240W for two in series). ... show more

    • 1 Star – Absolute Garbage. Expensive Lesson Learned.
Size: 12V 7Ah-2PACK
Review Image by BigSport
Review Image by BigSport
These batteries are a perfect example of paying more and getting less. I run 10 identical solar-powered trail camera setups. Eight of them use cheap sealed lead-acid batteries. Two were upgraded to these supposedly superior LiFe batteries because I bought into all the marketing hype about longer life, better performance, and superior reliability. What a joke. After just 5 months, both LiFe batteries were effectively dead. Neither will charge above 3 volts. They're nothing more than expensive paperweights now. Meanwhile, the "outdated" lead-acid batteries in my other setups keep chugging along without issue. Some have been in service since November 2024 and are still charging and operating normally under the exact same conditions. Apparently the old technology didn't get the memo that it was supposed to be inferior. What's most frustrating is how aggressively these batteries are marketed as a premium solution. Premium price? Absolutely. Premium performance? Not even close. If a battery can't survive half a year in a solar-powered trail camera application, then all the marketing buzzwords in the world don't matter. And let's talk about the Asurion protection plan. Don't waste your money... its a gimmick. The entire thing feels designed to give buyers a warm, fuzzy feeling at checkout on the "extended" 2 year warranty. When the batteries failed, I expected the coverage I paid for to actually do something useful. Instead, I got a canned apology and was told the batteries weren't covered. Their grand solution was to refund the protection-plan fee. Thanks for nothing. Really., then why is this even offered when you buy the d*** things. So let's add it all up: Batteries failed in 5 months. Batteries won't charge above 3 volts. Cheap lead-acid batteries dramatically outperformed them. The warranty was effectively useless. I paid more for a product that delivered less. I could have walked into Walmart, bought an $18 sealed lead-acid battery, and probably saved myself time, money, and aggravation. Bottom line: These batteries weren't an upgrade—they were a downgrade with better marketing. I won't buy them again, and I wouldn't recommend them to anyone running a solar-powered trail camera setup. Save your money and learn from my mistake. ... show more

    • SLA killers - light & powerful
Size: 12V 7Ah-2PACK
I installed these into an APC XS1300 to replace the SLA batteries that had failed. The UPS recognizes them and works flawlessly. I'll see how long they last and update if they don't hold up. Outside of longevity, they are much lighter then the SLA batteries and keep the devices plugged into the UPS online longer, as well (using the same load/devices as the SLA batteries). ... show more
