Product Description

Two main methods for battery cell charge balancing: passive and active balancing.
The natural method of passive balancing a string of cells in series can be used only for lead-acid and nickel-based batteries.

Active balancing method can be used for all types of batteries, but is effective for a small number of cells in series. The active balancing method is based on the active transport of the energy among the cells. This balancing method does not depend on the chemical characteristics of the cells, and can be used for most types of modern batteries.

This voltage balancer does not waste energy in resistors; it transfers the coulombs from a strong cell to a weak cell.

This is ideal for electric vehicles to prolong its battery cycle life by preventing cell over/under charging; promoting cost-effective sustainable transportation.

Batteries are expensive, this project will help any diy electric vehicle battery to last longer.
