Product ID # 6376
Part Number:

Lead Time: 5 Business Days!


  • Made of 4 pcs LiFeMnPO4 Prismatic Module: 3.2V 20Ah in 4S configuration with Plastic box  
    • Have s balance PCB on each LFP cell, it will maintain battery power and increase cycle life   
    • All picture are for demonstration purpose only.
Voltage 12.8 V (working)   15.2 V (peak)  10.0 V ( cut-off)
Capacity 20Ah (256Wh)
  • 3 tabs (90 degree) Faston 0.25 brass (part# A27871-ND)
    • 90A Max discharge rate (30A Max per each vertical tabs). 
  • 4x 3.2V LED balancing PCB installed on each cell to maintain balance voltage after charging.
    • Nominal Cell Voltage: 3.20V
    • Load Turn On Voltage: 3.60 +/- 0.25V
    • Balance Current: 0.25A
    • Current consumption : < 0.001A
    • Green LED On: "Finish Balancing / Ready to discharge"
    • Red LED On:  "Operate Balancing"
Cycle life >1000 cycles (80% of initial capacity @ 0.2C rate, IEC Standard)
Energy Density 78.76Wh/kg 
Charging rate
  • 1C rate (20A) Recommended

Max. Discharging Rate
  • Constant discharge current: 40A (2C rate)
  • Impulse discharge current (<10sec): can reach 200A (10C rate) if without Faston 0.25 brass connector.   
Dimensions(LxWxH) 178mm(7.0") x  76mm (3.0")  x 176mm(6.9")
Net Weight 3250grams (7.0 lbs 2.8 Oz )----   48.81% less than 12V 20Ah Lead Acid Battery
Note International Customers: Due to the high shipping cost , we are sorry we do not issue warranty, return or refund for this item. You are buying at your own risk.


  • Can replace 12V 20Ah Lead Acid Battery or 12V 17Ah Lead Acid Battery with 5 times more cycle life and 48.81% less weight with similar size
  • A Perfect 12.8V Battery module with 200A Max drain rate for EV, HEV application 
  • You may build battery pack for higher voltage (series connection) or higher capacity (parallel connection) 
  • Burn-time =  256Wh / motor's wattage
What are the advantages to these cells compare to LFP-P20Ah?
  • Superior safety performance due to patented new safety valve and pressure cap designs; 
  • Batteries do not explode or catch fire when batteries are shorted or punctuated resulting in internal shorts; 
  • More robust connection due to new electrode terminal design; Prevent loose connections caused by vibration; 
  • Reduced impedance due to improved electrode terminal design; 
  • Improved cycle life;  
  • New cell structure better facilitates BMS integration and battery pack formation, and improves air circulation.


  • 12.8V LiFeMnPO4 Prismatic battery pack shall be cut-off at 15.2V during charging and 10.0V during discharging. If over discharge to 10V (2.5V/cell), please recharge the pack right away. Otherwise the battery is over discharge and cannot recover!
  • Must remove 3 tabs (90 degree) Faston 0.25 brass if discharge current >90A
  • Must DIY with correct wire gauge size.
