Scenario based selection strategy guide for 18650 batteries.
There are significant differences in the cost performance evaluation criteria for
18650 lithium batteries in different application scenarios:
1. Outdoor power users: It is recommended to choose a 4000mAh battery pack that supports 0.5C fast charging, with a budget controlled between 400-550 yuan
2. Electric tool manufacturers: Priority should be given to low-temperature combinations with 20A discharge, with a reasonable price range of 600-800 yuan/10 units
3. Energy storage system integrator: For industrial grade battery packs with a cycle life of over 2000 times, the purchase price for a single pack (50 cells) should be less than 8500 yuan
4. Personal DIY enthusiasts: You can choose to purchase the B-grade battery cell assembly kit, which includes a 10 section set with a protective plate and costs about 280 yuan
5. A procurement case from a well-known drone manufacturer shows that by using a customized 18650 battery pack (with a capacity of 3500mAh and support for 30C pulse discharge), the cost of a single pack is reduced by 19% compared to standard products, while ensuring a 25% increase in flight time. This verifies the cost optimization value of precise selection.
