LED Street Light Lifepo4 12V Lithium Battery High Energy Density  CE / ROHS / SGS

• Description

12v 80Ah Lifepo4 battery is our hot sale products, it has widely used in LED light , emergency light, electric drills , toys, torch and others. This battery pack is composed by 32650 cells. Lifepo4  battery have many advantages than lead acide battery, such as lighter and small, the weight  is 1/3 lead acid battery , eenvironment friendly , long lifecycle , it can get 3000  time at 1c .

• Advantages of optimum Battery safety

1.  for cells:

• Break Protection: When the internal pressure in the single cell reaches its limits, the Gas Release Vent will turn around, the positive and negative welded plate shall break apart, the circuit inside shut down
•  Anti-explosion Protection: If the air inside the cell or liquid injection is too much, or over charge, over discharge, then the pressure could reaches its limits, the Gas Release Vent shall be cracked, through which the air can be quickly exhausted, and then the explosion can be avoided.
• PTC Protection: PTC is the heat sensitive device, which can be used to protect the battery pack against over current or high temperature, when it’s over current or overheat, the resistance of the PTC shall be raised, until it becomes the insulator, the current can’t pass through, the whole circuit ought to be shut down.

the point 3 only for the high rate cells for electric vehicle, we do not produce such cells now, our 32650 cells without this protection

         2. for battery pack

We have the PCM(with MOS) and PCB for safety protection
