Discharge curve for lifepo4 battery
WebThe flat discharge curve makes it difficult to determine state of charge (SOC) with a voltage reading alone since a reading of 3.3 volts could mean 50% charged or even 70% charged. The voltage does climb from 3.4 to 3.6 over the final 90-100% SOC levels which should mean that if you see a reading of 3.4v you are at 90% charged.
