LiFePO4 Marine Battery Description:


EA ENERGY lithium iron batteries have excellent quality since they are manufactured by Automotive Grade LiFePO4 Cells with more stable performance, high energy density and greater power. Lithium iron phosphate batteries have CE certificate and pass UN 38.3, MSDS Test. With no acid in the battery, you're able to safely mount in any position. This makes li-iron batteries perfect for solar home, RV, campers, golf cart, motor homes, off-grid applications.


Our 12V 300Ah LiFePO4 Batteries live more than 2000 cycles at 100%/8000 cycles at 50%(Suggested) depth of discharge, without decreasing in performance. The average lifetime of lead-acid batteries is about two years(500 cycles) at just 50% discharge. This basically means a LiFePO4 battery will last you at least 5 times longer than a lead-acid battery, which actually reduces overall cost.


EA ENERGY LiFePO4 battery’s flat discharge curve keeps above 12.8V for up to 95% of its capacity usage, offering astronomical boosts in run-time compared to only 50% in Lead Acid. Without memory effect, no matter what state the battery is, it can be used as soon as it is charged. As a solar energy storage cell, 12V Lithium Battery is a power supply for 12V household appliances, such as refrigerators, washing machines, TV, monitors and air conditioners.


EA ENERGY 300Ah LiFePO4 battery built-in 200A BMS, which supports 400A max. continuous charge/discharge current, 3840W max. Load power and 3840Wh max. energy. Equipped with exceptional quality 300A BMS can also limit the continuous charge/discharge current, our 300Ah LiFePO4 battery can better protect the battery performance and prolong the cycle times. We do 100% testing for all 300ah batteries before shipping them to you.


LiFePO4 Battery weighs only 51 lbs for one module, 30% lighter than that of lead acid batteries. It it an easier and more convenience choice for RV, Marine and Off-Grid Applications when mounting or moving.

EA ENERGY 12V 300Ah LiFePO4 battery provides 2000-5000 cycles, which is more than 10 times to Lead Acid with 200~500 cycles. EA ENERGY LiFePO4 battery has a 10-year service life, three times longer than the Lead Acid’s 3-year lifetime.
