williamhilapp威廉希尔_威廉希尔app版_威廉希尔中国 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
One cycle refer to one charge period and then one discharge period.
Cell Impedance:≤30mΩAssemblage Impedance: ≤80mΩ
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.
Relative humidity: 45~75%RHVoltage:3.8±0.1V(single cell)
