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.
