BMS suitable for super capacitors | DIY Solar Power Forum
What I am "concerned" about is that one cell can be 1.5V, another 2.5V and yet another 0.5V. I have a smaller 16V pack of 6 10F super caps with the simple protection circuit. I charged it to 15V and after using it a little bit I measured unbalanced voltages like that. A few were down to 1.1V, others 1.4V and one or two were 0.6V.
