To calculate the capacity of a lithium-ion battery pack, follow these steps: Determine the Capacity of Individual Cells: Each 18650 cell has a specific capacity, usually between 2,500mAh (2.5Ah) and 3,500mAh (3.5Ah). Identify the Parallel Configuration: Count the number of cells connected in parallel.
Capacity can be tested using a multimeter or a battery analyzer that measures the discharge rate over time. Battery management systems (BMS) in devices often monitor capacity and state of charge. How do I know what size lithium battery I need?
Formula #1 (Best For Large Capacity Batteries): Battery runtime = (Battery capacity Wh × battery discharge efficiency × inverter efficiency, if running AC load) ÷ (Output load in watts). Formula #2 (Best For Small mAh Batteries): Battery runtime = (Battery capacity Ah/mAh × battery discharge efficiency) ÷ (Output load in amps/milliamps).
Amount of charge the battery can store, determining how long it can power a device. Larger capacities mean longer run times. Common consumer batteries range from 2,000mAh to 100Ah or more for industrial use. Total energy the battery holds, calculated as capacity in Ah multiplied by voltage. Important for understanding total energy in the battery.
Charging Time of Battery = Battery Ah ÷ Charging Current T = Ah ÷ A and Required Charging Current for battery = Battery Ah x 10% A = Ah x 10% Where, T = Time in hrs. Example: Calculate the suitable charging current in Amps and the needed charging time in hrs for a 12V, 120Ah battery. Solution: Battery Charging Current:
Lithium battery capacity is typically measured in ampere-hours (Ah) or watt-hours (Wh), indicating the amount of charge it can hold.
