    Specifications 

    1. Safe
    2. Attractive cycle life
    3. Wide operating temperature range
    4. Environmental friendly 

    Our Quality control system: 

    (1)1-principle: Guarantee the cell's performance 

    The current flows sthrough in lengthways and then cross-protection by small fuse 

    (2)3-protection: Make sure the battery safety 

    >>>Break protection: 

    When the internal pressure in the single cell reaches its limits, the Gas Release Vent will turn around, the postitive 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 reach 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. 

    (3)8-conformity: Make sure the battery stability and long lifetime 

    1. Conformity in capacity. 

    2. Conformity in impedance. 

    3. Conformity in self-dischargeing. 

    4. Conformity in voltage 

    5. Conformity in electricity 

    6. Conformity in CC charging 

    7. Conformity in discharge platform 

    8. Conformity in lifetime
