UPGRADED BMS AND BATTERY CELLS: 12v 660Ah Lithium battery has a built-in 300A BMS, with over charge protection, over discharge protection, over current protection and over temperature protection. Operating temperature: Charge at 32 ℉-113℉;Discharge at -4℉-140℉. The IP65 waterproof rating is higher than other chemical batteries. Also, the 12V 660Ah lifepo4 battery uses upgraded A cells, which have excellent qualityas. It can be safely used outdoors. LONG LIFE & DEEP CYCLE: Lithium iron phosphate (LiFePO4) batteries can be recycled more than 15,000 times and have a lifespan of up to 10 years. Due to its safety and stability, LiFePO4 batteries can completely replace traditional lead-acid batteries. Compared with traditional lead-acid batteries, its stability is better, the energy density is higher, and the weight is lighter, so that the battery performs well at high temperatures, has high power output and low self-discharge rate. LIGHTWEIGHT & PORTABLE: Product size: Length 24.05* Width 9.7* Height 8.7 inches. The E-LekTech 12V 660Ah LiFePO4 battery weighs just 104 pounds, half the weight of a lead-acid battery, and has twice the capacity of a lead-acid battery, making it easy to move and install. Our LiFePO4 batteries provide 100% of the available capacity compared to lead-acid batteries. Both indoor and outdoor, easy to carry. SERIES AND PARALLEL SUPPORT: E-LekTech 660Ah LiFePO4 Battery support extends to 6 series and 6 parallel circuits, supporting connection to solar panels, MTTP and inverters. Suitable for Marine, RV, RV and off-grid energy storage applications. Note that in the series parallel process, the batteries need to be fully charged separately so that they reach a voltage balance state. And be careful to use the same brand of battery. 5-YEAR WARRANTY: E-lektech offers a five-year warranty for the 12v 660Ah LiFePO4 battery. If you encounter any problems during use, we will help you analyze the problem within 24 hours, help solve the problem, restore the battery usage, and introduce the best use method. Factory Outlet & Professional After Service: We are a production factory with over 10 years of experience in lithium LiFePO4 battery research and manufacturing. In order to enable more people to use high-quality and cost-effective lithium batteries, we spent a year developing batteries and launching the E-lektech battery brand. We will definitely provide you with affordable and high-quality lithium batteries, and most importantly, we also have professional after-sales service!
High Energy Density & Small Volume: We use A-grade cells when producing LiFePO4 battery, which can maximize the advantages of high energy density, small size, and long lifespan of lithium iron phosphate batteries. As you can see, our battery size is smaller than most batteries of the same capacity on the market, and can be suitable for most use scenarios such as RVs, golf carts, and yachts.
REAL CAPACITY:
Our factory has strict production inspection standards. LiFePO4 battery with capacities lower than the standard capacity are discarded to ensure their true capacity.
Therefore, most of our batteries have a true capacity that slightly exceeds the labeled capacity.
As you can see, other brands of batteries may experience a capacity shortage, with severe cases leading to a 30% capacity shortage.
We have sufficient confidence in our battery capacity.
