Following on from ProgressBar madness…
After watching Balance Charging: Can you parallel charge?, I realised that I needed a clamp meter. But which one?
I had already purchased a UNI-T UT71D DMM, see Choosing which Multimeter to buy, and I was very happy with it, so the UNI-T clamp meter seemed a logical choice. Everyone seems to have the UNI-T 210E. However, there are a myriad of other options.
This blog leads on from the blogs Flight Controllers, see the section on APM/Additional Required Extras, (in particular Safetly Use CLONE APM Power Modules), as well as Low Voltage Warning for CC3D. There are varying reports that claim that these devices can pass the full battery voltage to the flight controller and fry it, but there are also others that say that this is scaremongering – so who is telling the truth? Also there are cheaper clones versions that lack certain components. This article explores both of these points.
