Shipment
At time of shipment, the cells’ state of charge shall be 20±10% of its rated capacity or less. The violent vibration, impaction or squeezing should be avoided in the transport process; neither is exposed in the sunlight nor rain. The cells shall be shipped by normal transportation such as by road, by ocean or by air.
Storing Condition
When long duration storage cells should be stored in a stable environment characterized by low-humidity (less than 70%RH), free of corrosive gasses, and an ambient temperature between 0℃and 20℃.
Product Advantages
Compared with conventional lithium-ion batteries, the low-temperature 21700 cell delivers superior capacity retention and stable voltage output in freezing conditions. It significantly improves device reliability and operating time for outdoor and industrial applications exposed to low temperatures.
The 6500mAh high-capacity design allows longer runtime and reduced battery replacement frequency, making it an efficient and cost-effective energy solution for demanding applications.
OEM and ODM customization services are available, including battery pack assembly, PCM/BMS integration, connector customization, and tailored voltage and capacity solutions according to project requirements.
