Why does Li-Po battery voltage drop under load? [closed]

$begingroup$ @Karn The two quantities are interlinked, the voltage will drop as you use up the battery''s stored energy. While you can get a more accurate measurement of the battery''s state of charge by monitoring both the voltage and the used charge (load current x time), for most applications, it''s not necessary to keep track of the stored energy to that …

How to Build A Battery Pack From 18650 Cells

When the electrical conductor used to join 18650 cells has a lower resistance, that means the battery pack will have less voltage drop under load. This leads to less heat generation during charging and discharging, which extends the battery''s life span while also ensuring that the battery maintains optimal performance throughout this …

Understanding Voltage in LiPo Batteries: A Comprehensive Guide

In summary, the charging voltage of a LiPo battery should not exceed 4.2 volts per cell, the nominal voltage is 3.7 volts per cell, the storage voltage should be around 3.8 to 3.85 volts per cell, and the discharge voltage should never go below 3.0 volts per cell.
