@hires,

It should be in balanced if you don't see any red LEDs.
Or, just measure the voltage over the two ultra capacitors.

Ian,

On the UcHybrid board there are only two LEDs:
D2 Power indicator and D1 condition indicator.
There is no overvoltage indicator.

In this situation it's impossible to understand that there is an ongoing imbalance.

Regards

When UcHybrid is fully charged, the voltage on each ultra capacitor will be only 1.65V, that's far from the 2.7V rated voltage. So, UcHybrid was designed to use passive balancer. There will be enough headroom and time to reach the balance point if the voltages are slightly different over the two UCs.
