Megacell Charger PRO Documentation

To get the most of your device, we recommend using it in combination with a computer with Windows 10 or Windows 11 for software compatbility. Megacell Monitor software is developed by a 3rd party that partnered up with us to support the megacell charger testing equipment. For more details please visit .

Each megacell charger comes with a license to use with Megacell Monitor application with max 3 devices connected per computer. You can get a more advanced license by contacting Martin from Connect & Exchange and requesting a quotation for the number of devices you own.

If you feel more rogue and want to use other platforms and OS’ses, I have developed a python library that can send commands and gether data from MCC PRO. Scrolls to download section for more info.
