low Temperature lithium polymer batteries can work at -40℃

  low Temperature lithium polymer batteries can work at -40℃, here we give you lithium polymer battery pack GMB6560158 29.4V 40Ah as an example(other sizes at your request):

 

  A、Introduction:

  Together with technology’s imporvement and actual demanding of low temperature batteries, there are many field in great demand of low temperature rechargebale ones.

  Currently, almost all of batteries ofChinabattery line can stand low temperature rate at minus 30 degrees.

  While GMB’s low tem battery can stand at most minus 40 degrees.

 

  B、For instance, GMB6560158 battery packs, our’s low tem version have following charcteristics as well.

  Scope:

  This document is made according to customer parameter requirements,it describes the Product Specification of Chargeable Lithium Polymer Battery produced by Guangzhou Markyn Battery Co., Ltd.

  The temporary specification is only for the customer's reference, not regared as the basis of the IQC and mutual confession

C、Specification

    No.    Item    Spec    Note
    1    model    6560158/40Ah    8P7S
    2    Charge Voltage    29.4V(single cell 4.2V)   
    3    Nominal Voltage    25.9V    The average value of voltage during the discharge period (with standard charge and discharge). When shipping, the voltage without load is between 25.2V and 26.95V.
    4    Nominal Capacity    8P:40Ah Min:38Ah    Nominal Capacity refer to the capacity of0.2Cdischarge to 19.25V cut-off voltage, after charging with standard method.
    5    Cycle Life    ≥300 Times

      One cycle refer to one charge period and then one discharge period.

      Test condition:

      Charge:0.2Cto 29.4V

      Discharge:0.2Cto 19.25V

    The cycle life is the cycle times when the discharge capacity is about 75% of the rated capacity.
    6    Impedance

      Cell Impedance:

    ≤30mΩAssemblage Impedance: ≤80mΩ
    After Standard charging, measure the internal resistance with AC1KHz (while measuring, clip near 2/3 place of the anode and the cathode.);Measure two sides of the drawing line after assembling. (Red B+、Black B-)
    7    Max. Charge Current0.5C   
    8    Max. Discharge Current1.0C   
    9    Discharge Cut-off Voltage19.6V   
    10    Operating Temperature

      Discharge:-40℃~ +55℃

    Charge:-40℃~ +45℃

      Cells must be stored at 25.2V ~ 27.3V. Over long storage periods cells should be cycled every 90 days. The method is to do a charge-

    discharge cycle with standard method, then charge to 25.2V~ 27.3V.
    11    long term storage temperature    -5 ℃~+35℃

      Relative humidity: 45~75%RH

    Voltage:3.8±0.1V(single cell)
