Product Description


12V250AH Lithium Lifepo4 Battery, Deep Cycle Batteries Built-In 200A BMS



About this item:

  • 【Deep Cycle & Long longevity】 How is the longevity of this battery? If not charged to 100% and not discharged to 0%, leaving about 10% on charge and discharge, LiFePO4 battery life can be recycled up to 4000-8000 times and lives up to 10 years. Just be sure to get a battery charger specifically designed for lithium iron phosphate batteries.
  • 【Automatic BMS and Quickly Charge】 Compared to other chemistries, LiFePo4 offers higher energy density, more stability at higher temperatures, and better performance, making the batt charge quickly, discharge flatly, and last longer. Our battery built-in BMS protects it from overcharge, deep discharge, overloading, overheating and short circuit, and low self-discharge rate ensuring up to one 1-year maintenance-free.
  • 【Uncompromising Quality】 State-of-the-art battery cells ensure a lifespan of more than 5000 cycles, 150A continuous discharge current, and a wide operating temperature range.

Safty performance:






Test Method and Condition






Thermal exposure test



Each fully charged cell, stabilized at room temperature, is placed in a circulating air-convection oven. The oven temperature is raised at a rate of 5 °C/min ± 2 °C/min to a temperature of 130 °C ± 2 °C. The cell remains at this temperature for 10 min before the test is discontinued.


No fire, No explosion



Low pressure



Each fully charged cell is placed in a vacuum chamber, in an ambient temperature of 20~25℃. Once the chamber has been sealed, its internal pressure is gradually reduced to a pressure equal to or less than 11.6 kPa (this simulates an altitude of 15240 m) held at that value for 6 h.


No leakage, No fire, No explosion



Short test



The fully charged battery is to be short-circuited by connecting the positive and negative terminals of the battery with resistance load not exceed 100mΩ. Tests are to be conducted at room temperature 20~25℃.


No fire, No explosion

The Temperature of the Battery surface not exceeded than 150℃




Over Discharg




(After standard charge. Cells are discharged at constant Current of 0.2C to 2.0V, and the positive and negative terminal is connected by a 30Ω wire for 24 hours. Cell Condition: Fresh, Fully charged cell.)


No fire, No explosion


Over charge test



After standard charge, continue to charge with a constant voltage 4.8V per a cell, holding 8h.


No leakage, No fire, No explosion



Soak Test



Put the batteries into clean water, be soaked for 24 hours.


No break, No fire






Risk of Fire , Explosion or Burns

DO NOT Short circuit
DO NOT Reverse connections from charger to battery

DO NOT Disassemble
DO NOT Throw into fire or incinerate

DO NOT Heat above 70C
