Weighing only 7 kg, it is significantly lighter than traditional SLA batteries, making it an eco-friendly choice with no hazardous materials. ## Description 1. This battery with BMS(Battery management system) which can turn off the power automatic while the battery under-voltage, for example, you forget close the headlight or car door in night, the SLA battery will dead, but the LifePo4 battery will turn off the power automatic when the voltage low than 10.5v, you just press and hold the power button for 2-3 seconds to turn on the power again, then you car can start without any jumping cable. 2. Long service life. Its cycle can reach as long as 2000 times which is 7-10 times of SLA （the SLA battery is 300-500 times only） 3. The attenuation rate of LifePo4 Battery is 15% per year, and SLA is 40% per year 4. Cleaner for the environment , No HAZMAT . while LiCoO2 and SLA cause serious pollution to the environment . 5. High security .Our battery is 100% safe lithium battery in the world .It will never catch fire or bomb under worst condition 6. LifePo4 battery can deep discharge till 100% DOD. Even the voltage goes down to nearly 0 volt shortly, it can still recharged to rated voltage 7. LifePo4 battery can working on high temperature 160°F and cold temperature -60°F. 8.LifePo4 batter don't include any liquid then it is maintenance free. 9. Good performance, Lightweight. Weighs about 1/3 of same capacity SLA Battery 10. Extremely Low self-discharge. 20% for SLA Battery" Review: Extremely Clever Design! - I purchased this as a backup power source and to run an Engle 12 volt ice chest in the event of power failure. It runs the ice chest for a day and a half and then the battery shuts itself off to preserve enough power to start a vehicle. The first thing I noticed about the battery is it’s unbelievably lightweight, compared to a conventional battery. Obviously this is a big plus for portability. The built in handle is brilliant. Why don’t all batteries have that? The on-off switch is also very handy. There is a LED which slowly flashes around the push button switch to let you know it’s “on.” The way it disconnects itself when it gets low on charge is brilliant. It is pricy, but with all these features I think it’s well worth it. Review: 5 years and going strong - Update 11/7/25 - Found battery was going dead, after troubleshooting found that the Dirty Parts Wrangler solenoid I had installed in 2015 had a voltage drop of nearly 0.7 VDC, this battery is a 2nd battery in the FJ so it wasn't getting fully charged when I would run the car. I purchased a stinger 200 amp from desertcart which was a direct replacement and now I get full voltage to the battery. I still have a small solar panel connected to the battery but I had parked under a tree for several weeks do to some yard work. I had started the car a few times during that period to top off the battery, but noticed the battery went into low voltage mode after a day. Usually 5 minutes of leaving the car on would keep it topped off for at least a week, that's what lead me to dig into what was happening and I found the drop in voltage on the NO contacts on the solenoid, all good now, 5 years and this battery is still going strong Put this is a 2nd battery in a 2014 FJ Cruiser, I use it full time to power a "Loraffe Under Hood Animal Repeller Ultrasonic Rodent Repellent LED Rodent Strobe Light Ultrasound Device" which I bought of desertcart. This battery is basically charged regularly from a 20 watt solar panel on the FJ Roof Rack and the strobe/sound device runs 24/7. Had to install this as Rodents ate the wiring on the FJ Knock Sensor (twice within a year) this battery has been doing it for 4 years and also doubles as a backup starter battery. I just replaced the Main FJ Battery with Ionic Lithium Start battery. ## Features - This Automotive Battery Included A Bms Battery Management System Which Can Turn Off The Power If It'S Drained Below 10.5V, For Example, If You Forget Close The Headlight Or Car Door, The Sla Batteries Will Dead After 10 Hours, But The Lifepo4 Batteries Will Turn Off The Power Automatic When The Voltage Low Than About 10.5V, You Just Press And Hold The Power Button For 1 2 Seconds To Active It Again, Then You Car Can Start Without Any Jumping Cable - Lifepo4 Battery Can Deep Discharge Till 100% Dod. Even The Voltage Goes Down To Nearly 0 Volt - Cleaner For The Environment , No Hazmat . While Licoo2 And Sla Cause Serious Pollution To The Environment . - Good Performance, Lightweight.

It will get below freezing.** A: I would just charge it up and leave it all winter. It's NOT like a lead-acid battery that needs: a trickle charge, will dissipate rapidly on its own and will damage the battery if discharged to much. Do NOT attempt to charge a frozen Lithium battery- BMS will not allow it either. Lithium requires a new way to think about batteries. **Q: would it last longer under a 40amp draw from a winch then a yellow top optima Deep cycle?** A: It is a 50AH battery, then the time depend the capacity, they have 200AH battery, you can contact the seller or manufacturer of EASTUP. **Q: What is the product warranty on this battery?** A: 3 Years ## Customer Reviews ### ⭐⭐⭐⭐⭐ Extremely Clever Design! *by S***7 on 20 October 2017* I purchased this as a backup power source and to run an Engle 12 volt ice chest in the event of power failure.

Due to work I gotta travel abroad several times a year. The battery in the car was drained most of the time when I got home. Even though we can jump cable to get the engine started, it does hurt the battery a lot. The most embarassing moment was that I couldn't start my car when I was attending parties or went shopping. I replaced 4 batteries in the past 6 years including Duralast in Autozone. I've been seeking better solution for my situatuon and fortunately I found this one. It's not cheap but I saw it's promoting a 10-year life and I don't needa jump cable over and over again after I travel. Therefore, I decided to give it a try. I couldn't wait to turn on my car after my 1st trip since I used this battery. The power is still out, but I just simply hit the reset buttom on the battery and it just resumed functional!! I can't be more excited than that! I was excited to test out some various situation that would drain the battery, but it just started smoothly. I'd say I'm sooo lucky finding this battery, or else a lot more time will have to be spent dealing with those drained batteries. Hopefully this review would help the guys who have the similar situations. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/72625846-eastup-1250750-lithium-iron-phosphate-lifepo4-automotive-replacement-battery-12v](https://www.desertcart.jp/products/72625846-eastup-1250750-lithium-iron-phosphate-lifepo4-automotive-replacement-battery-12v) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-29*
