The ToolkitRC M8 charger looks better than I thought and the photo in the descriptions. The charging works fine, and I really like feature of the constant voltage/current supply mode (haven't tried it yet though). One issue I have is that the cell balancing does not work properly. It looks like a complex cell balancing algorithm is performed, but does not give proper results and the cell with the highest voltage is over charged. I found that many users online have the same issue with ToolkitRC chargers. In the photo, one of the cells reached to 4.22V even though the setting was 4.20V. The AMASS XT60 Charger Board is very good in build quality, and I love it.
