Under the condition of 20 ± 5 ° C, the packed lithium battery falls from 1200mm (the lowest point of the battery) to 18-20mm thick hardwood (the wood is paved on the cement floor).
Results: there is no fire and explosion during and after the test.

Under the ambient temperature of 20 ° C ± 5 ° C, the battery falls freely to the concrete plate or metal floor at a height of 1m for 3 times.
Result: no fire, no explosion.
After the battery is fully charged according to the charging procedure specified by the manufacturer, it will fall freely to the concrete plate at a height of 1m.
