Looking for someone with a Hyperion Charger

[Arct1k]

It won't stop straight away but leave it and it will be fine. These chargers give a constant current charge rate at 75% the cell capacity until the pack voltage reaches 3.6 volts per cell. This charges the pack to about 80% of total capacity. At this point the charger switches to a constant voltage charge rate of 3.6 volts per cell to top off the battery. To charge a fully depleted pack typically takes about one and a half hours.

Press the left hand button once charging and you can scroll through the settings including input/output voltage and individual cell voltages. ATB.
