Supercap / battery hybrid did not drop voltage before. Even when left parked for 38 hours in -5°C weather, still held ~12.5 volts and gave a start. It died suddenly when outside temps dropped to -11°C, no warning.

Only the supercap array lost voltage, when charged and left with no battery attached.

Can't the supercaps run with no balancer at all, as long as alternator voltage doesn't climb over 14.7 volts overall?
