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.

Applications

  • 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.

Warnings

  • 12.8V LiFePO4 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.
