Product Description
The natural method of passive balancing a string of cells in series can be used only for lead-acid and nickel-based 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.
