11 Jan, 2021 - Grepow release the latest low-temperature series to break through the lowest discharge temperature to -55℃. This series of Lithium polymer pouch cell batteries, discharge at -55℃ to 2.5V can remain a maximum of 63.5% discharge efficiency.

-55℃ Ultra Low-Temperature Lithium Polymer Battery

We conduct the testing at -55℃ with 0.2C rate discharge, without any pre-heated function or materials, according to the discharge curve below, the battery can successfully discharge at -55℃ and remains 63.5% efficiency. The first dropping point is around 2.7V and maintains a stable voltage till the cut-off voltage 2.5V.

-55℃ Discharge Testing Test

It shows that the Grepow Low-Temperature battery can operate normally and stably at -55℃, it is the strength to compare with most low-temperature batteries on the market, they are cautious about 30% efficiency at -40 or -50℃, and even unable to discharge electricity.

-50℃ Discharge Testing

Grepow Low-Temperature battery operates at -50℃, can reach a maximum of 83.8% efficiency with 0.2C rate discharge, it also allows 0.5C rate discharge at -50℃ temperature environments.

-40℃ Discharge Testing

At -40℃ low-temperature environment, the battery can reach a maximum of 88.74% efficiency with 0.2C rate discharge, and a maximum 1C high rate discharge with 86.1% efficiency.
