This small circuit can be used to replace the dump resistors from a slot from megacell charger and charge a 3.6 or 4.2V lithium cell. The small switch on the board allows you to select the voltage of the cells you are dumping energy into. It has a Max 3A power draw capability and the discharging current will be set from megacell charger, variating the load.
This is perfect for testing large cells withouth wasting energy. More info about setup and video coming soon.
