Did you calibrated your current measurement correctly as the value BATT_AMP_PERVOLT is on default?
I calibrated the voltage reading but I wasn’t aware that I also needed to calibrate the current reading. I read on the wiki that for a Pixhawk with a 3DR Power module that value is to be kept 17 and so let it be. After some googling I found this article and will use it to try and calibrate BATT_AMP_PERVOLT. Thank you!
Consider a subscription to https://ecalc.ch/ The price of one month is less than a couple of propellers and will save you tons in the long run when you compare batteries, motors, props, etc.
I was just messing around with the free version a few hours ago and found it quite useful. I will consider subscribing and playing around a bit more, thank you for the suggestion.
I am still a bit lost on how to choose the cell count for my batteries depending on my motor specs. Any ideas where I can find more info on this? A google search does not turn up very useful results.
