I've got accustomed to monitoring the battery cell info provided by my Phantom 3 Pro and really miss it with the Typhoon H. So, to ease my mind I decided to check if the cell balance volts on my H batteries were OK. Here's what I found. Full battery (100%) Total (16.96V), Cell1 (4.24V), Cell 2 (4.24V), Cell 3 (4.24V), Cell 4 (4.24V) Used battery (???%) Total (15.56V), Cell 1 (3.88V), Cell 2 (3.89V), Cell 3 (3.89V), Cell 4 (3.89V) The percentage of a used battery is still a mysterious black art to me. Anyway, here's how I got the cell readings.
