12V 18650 Battery Pack Design

  • 18650 battery cell selection. We will evaluate customer requests, trying to find suitable 18650 cells. They can be LG, Samsung, Sony or Chinese brand cell. We can also choose 1C, 3C, 5C, 10C and high power cells. Also costing counts much more when considering 18650 battery selection.

  • PCBA design. Lithium batteries cannot be overcharged, overdischarged, or overcurrent due to the relationship between materials. At the same time, short circuits and charging and discharging at ultra-high temperatures will also cause great risks. Therefore, lithium batteries are usually equipped with protective plates and used at the same time.

    The design functions of the lithium battery protection board include the following points:
    1. Overcharge detection voltage
    2. Overcharge release voltage
    3. Overdischarge detection voltage
    4. Overdischarge release voltage
    5. Overcurrent 1 detection voltage
    6. Overcurrent 2 detection voltage
    7. Load short circuit detection voltage
    8. Charger detection voltage
    9. Current consumption during normal operation

  • We shall also pay attention to battery pack artwork and process.
