1 Such as 5C or 10C discharge is set to 0.8V / branch;. 4, in general, high temperature battery over-discharge will increase the internal pressure of the battery, and the positive and negative active substance is reversible, even if charging can only be partially recovered, the capacity will also be distinctly attenuated.

From the self-discharge on the lithium ion battery pack, self-discharge can be divided into two types: loss capacity can reverse the self-discharge of compensation; loss capacity cannot reverse compensation self-discharge. The more the lithium-ion battery pack is discharged, the greater the loss of the battery. The lithium-ion battery pack is preferably in an intermediate state of electricity, and the longest battery life is the longest.

After the lithium ion battery is put on the amount of internal storage, after the voltage reaches a certain value, the continuous discharge can cause over-discharge, which is usually determined according to the discharge current to determine the discharge cutout voltage. 0.2C-2C discharge is typically set 1.

0V / branch, 3C or more, such as 5C or 10C discharge setting is 0.8V / support, battery excess may bring catastrophic consequences to batteries. .
