LIFEPO4 – Internal Resistance, capacity, and its Performance
Cell capacity is of limited use if a battery pack cannot deliver the stored energy effectively; a battery also needs low internal resistance. Measured in milliohms (mΩ), resistance is extremely important the higher the C rate of the battery; the lower the resistance, the less restriction the pack encounters.
What is Lithium Battery C-rate and How to Calculate it?
The C-rate of a lithium battery shows how quickly it can charge or discharge compared to its capacity. To calculate it, divide the charge/discharge current by the battery''s capacity. For instance, a 2000mAh lithium battery discharging at 1A is 1C. Factors like battery chemistry and size affect C ratings.
