What temperature range is safe for charging the Intelligent Flight Battery?

The battery only charges at temperatures from 5° to 40° C (41° to 104° F) to prevent damage, and charging stops automatically if the battery cell temperature exceeds 55° C (131° F) during charging. The ideal charging temperature is from 22° to 28° C (71.6° to 82.4° F). Additionally, you should not charge the battery immediately after flight as it may be too hot — wait for it to cool down to room temperature first.
