Testing Your Lithium Battery Capacity

Modified on Fri, 15 Sep, 2023 at 11:28 AM

Step 1: Fully charge your battery using the appropriate lithium battery charger. Make sure you're using a charger compatible with your battery's chemistry. 


For example, there are specific LiFePO4 battery chargers for LiFePO4 batteries or you can also use a smart charger that can be adjusted to your battery's charging profile for optimised charging. 


Step 2: Check the output current of the load/appliance you'll be connecting to your battery. You can either use an ammeter for this or check the specs sheet of the appliance. 


Step 3: Record the discharge time. Note: No output after the BMS protection kicks in means the power has been drained.


Step 4: Calculate the battery using this formula:


Output current x Discharge time = Battery capacity


Example


9.6A(output current of load/appliance) x 11 hours(discharge time) = 105.6Ah
