High-current Battery Balancer PCB (April 2022)

PCB for the Digital FX Unit project in the April 2022 issue of PE.

Proper balancing is critical for a long battery life, especially if they are lithium-based rechargeable types. But many balancers are inefficient, as they dump excess charge for a given cell, restricting how fast you can charge the batteries and wasting power. Not this one – it redirects that extra charge into other cells, so you can charge fast with little heat or waste!

Please note this PCB is supplied without components.
