Leaving a lithium iron phosphate battery with less than 10% charge overnight is not an ideal practice. This is because a phenomenon called over-discharge occurs when lithium batteries are in a low-consumption state, especially when they are near or reach zero power.
Over-discharge means that when the battery is in a low-power state, the voltage inside the battery continues to drop, causing the battery voltage to fall below its operating range safe. This may result in reduced battery performance or even permanent damage.
Therefore, it is recommended to charge as soon as possible when the battery power is less than 10% to avoid excessive discharge. If it cannot be charged immediately, you may choose to place the battery in a relatively stable environment to avoid discharge.e excessive and excessive discharge.
In addition, leaving the battery in a low power state for a long time can also cause the battery to self-discharge, that is, the battery discharges itself. even when not in use. This will cause the battery charge to further decrease.
In short, in order to protect the performance and life of the lithium iron phosphate battery, it is recommended to charge it as soon as possible when the battery power is less than 10%, and Avoid leaving the battery in a low power state for a long time.
