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):
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 of
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.
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
|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 of|
|5||Cycle Life||≥300 Times|
One cycle refer to one charge period and then one discharge period.
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 Current||0.5C|
|8||Max. Discharge Current||1.0C|
|9||Discharge Cut-off Voltage||≤19.6V|
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.
