Neexgent Tower Power Supply 51.2V 300Ah Lithium Ion Lifepo4 BMS Battery

NX03-48300 tower energy storage battery is a highly versatile deep cycle battery built on patented Lithium Iron Phosphate (LiFePO₄) chemistry. The battery pack features a built in battery management system (BMS) that keeps the battery running at peak performance while preventing overheating, overcharging, and maximizing cell cycle life. 


NX03-48300  51.2V 15KW Lithium Battery:

● Maximum safety performance with LFP technologies
● Built-in aluminum heat sink, optional heating solutions
● Compact design with flexible size options
● IP54 protection for indoor and outdoor use
● Compatible with leading inverter brands
● Black start function available, quick installation

NX03-48300 tower energy storage battery consists of 16 pieces of 3.2V 300Ah Li-FePO4 cells combined in 16 series and 1 parallel connection. 


NX03-48300 tower type energy storage adopts scientific internal structure design and advanced battery production process, which has the characteristics of high specific energy and long life, safety and reliability, wide temperature range, etc. It is a green energy storage power product.


Product Features:

  • Internal BMS (electronic chip) monitors battery in real time and alarms the user if any voltage or capacity abnormalities are detected. 
  • At only half to a third of the weight of a Lead Acid battery, LiFePO4 is the ideal choice for Marine, RV, Golf Carts,Motorcycles and Off-Grid applications. 
  • Without any corrosive or harmful heavy metals, Our LiFePO4 lithium Batteries are more environmentally friendly than SLA batteries. 
  • LiFePO4 batteries have a low discharge rate and long service life, with an average life expectancy of about 5 to 10 years.
