- Charging and Discharging Requirements: The battery pack can be designed according to the operating requirements of the equipment, including charging method, continuous discharge current, peak discharge current, and expected operating time.
A 3C discharge rate means the battery can theoretically discharge at three times its rated capacity per hour. For a 2900mAh battery cell, this corresponds to a theoretical discharge current of 8.7A. The actual permitted current depends on the manufacturer's specifications, operating temperature, and thermal conditions.
The required charging voltage depends on the specific lithium-ion chemistry used in the cell. Many conventional 3.6V nominal lithium-ion cells use a 4.2V maximum charging voltage, but this must be confirmed against the manufacturer's datasheet before selecting a charger.
MSDS and UN38.3 reports are standard, and further certificates can be arranged on request.
Store the cells in a cool, dry environment within the manufacturer's recommended temperature range. Avoid short circuits, crushing, puncturing, direct heat, and contact with water. Use suitable packaging and follow applicable lithium battery transportation and storage requirements.
