A1103 Active Cell Balancer For Lithium Battery
In Stock
In the process of charging / discharging a lithium battery, due to the spread of internal resistance and self-discharge of the cells of which it consists, they (cells) are unbalanced (different voltage on the cells).
The balancer allows you to limit the upper voltage threshold for the cells.
This happens by shunting the cell with a load resistor. As a result, excess energy is converted into heat.
